Factory commercial ball bearings

The linear rail is a device widely used in the industrial sector. The industrial sector today uses two types of linear guides : the runner with ball bearings and the runner with rollers. The linear guidance system consists of two parts: the rail and the runner. The latter moves inside the rail, from front to back. Recirculating balls or roller bearings are the moving parts of the assembly.

Ball Bearing Hinges

Engineering centers of the UPEC IG and HARP plant have completed a year development of a new generation of railway cartridge bearings of extended service life for the track of 1, mm. For more details about the new developments of the UPEC and the stages of their implementation, refer to the author's article of Director for Research and New Developments of U. Joint Stock Company E. It is difficult to name anything more important for equipment and machinery than a bearing.

Perhaps only a wheel. They have been spinning together from the times of ancient Egyptian and Roman civilizations solving the main task — reducing friction during the movement. The great Leonardo da Vinci and Galileo Galilei, many outstanding engineers and scientists were involved in the development of bearing designs at different times.

Without high-quality bearings, modern engines, cars, agricultural machinery, rail transport, aircrafts, armoured vehicles, machine tools, and virtually all mechanical engineering and even space engineering would not be possible. Nevertheless, there is a wrong idea about the bearing as the simplest assembly being easily manufactured.

This is a deeply erroneous view. A modern bearing requires the development of steels and other structural materials with very specific properties, complex heat treatment, optimal internal geometry of contacting elements, unique machine tools that quickly reproduce this geometry by turning, grinding and superfinishing operations with micron accuracy, special coatings, greases and seals as well as the finest technology and quality control devices.

A strong bearing industry is a reliable sign of high-tech engineering. Today, one of the most complex bearing assemblies, without which it would be impossible to develop high-speed rail passenger traffic and freight traffic of increased load capacity is a tapered cartridge bearing.

Most recently, only a few world leaders in the industry was able to calculate and produce this assembly. Swedish company SKF - bearing company No. By the way, it is the founder of Timken, Henry Timken, who registered in a patent for a tapered bearing for wheel axles of horse-drawn transport of that time, and a year later founded a company that produces bearings for carriages of the railway transport.

Today's cartridge bearing assembly is a closed device assembled and lubricated at the manufacturing plant, fully ready for fitting and providing , to 1 million km run without any maintenance. The outer racer of a double-row tapered bearing plays the role of a traditional box body, and the loading is transferred from the side frame of the truck through a polymeric wear-resistant insertion to the adapter distributing the load along the outer racer. The cartridge assembly has smaller dimensions and is noticeably lighter than the traditional box assembly, while having a large load-bearing capacity.

Due to the more complex structure and production technology, the bearing itself is considerably more expensive than two classic cylindrical bearings inserted into the traditional box assembly, but this is justified in the cost of the life cycle by the absence of an expensive and unreliable system of depot scheduled maintenance with lube replacement and overhaul of rolling elements.

A cartridge bearing comes to the world on the threshold of the new millennium in China, which is actively developing high-speed and ultra-high-speed rail transportation, after the USA and Europe. In the same 's, SKF decides to build a factory in Tver to produce its own cartridge bearings.

Timken and FAG are also looking for their place in the huge market of "1, space" the territory of the former USSR with a characteristic track width of 1, mm. As a result, despite the former power of the bearing industry there were more than 30 gas state bearing plants in the USSR , there was no manufacturer in the market of 1, mm track ready for own development and production of a cartridge bearing, taking into account the specifics of the operation of "1, track space" railways of the territory of the former USSR.

In Kharkov, bearing steels with unique properties of heat treatment, advanced designs and technologies of cylindrical and ball bearings were mastered. The main emphasis was on mathematical modelling of strength and wear, three-dimensional optimization of internal geometry, modelling of basic technological processes and the creation of massive test beds for physical modelling of operating conditions. To automate the development and design processes, UPEC, jointly with the US company RTS one of the four world leaders of software platforms for supporting engineering activities implemented the largest in Eastern Europe project for integrated automation of developments in Designers, calculators, manufacturing engineers, plant managers, Engineering Centers and the Design Bureau of the UPEC obtained advanced specialized software products related to a unified database, corporate libraries and a unified project management program.

All this accelerated the development dramatically. The task was not simply to design a cartridge bearing, but to create a structure, materials and heat treatments that would be optimal in the composition of new cars and carriages accepted for use on the 1, mm track, and, most importantly, taking into account the specific operating conditions.

For this purpose, the dynamics of the train, deformation of the car and the carriage were initially modelled and, as a consequence, the loading conditions of the bearing assembly, taking into account the heavy operating conditions on 1, mm track.

Nonlinear mathematical models of the finite element method used to analyse and optimize the geometry of a cartridge bearing assembly contained tens of millions of degrees of freedom being record at that time. Every advantage has its "reverse side". One of the key advantages of a cartridge bearing — an eight-year operation period without replacing the lubricant — also has its reverse side.

In ordinary box bearings, during maintenance, wear products were automatically removed with the old lubricant. In a closed bearing assembly, wear should be virtually eliminated, because even the smallest particles of metal, gradually accumulating in the lubricant, will work as an abrasive, exponentially accelerating wear and outage of a bearing.

However, a new effective lubricant includes additives that are found to be incompatible with conventional elastomers used to seal the cartridge bearings. In , jointly with the German company Freudenberg Sealing Technologies Simrit and Italian Corcos, special elastomers chemically neutral to the Klueberplex-HARP lubricant were found, and the developed original design of the cartridge seals best combines effective sealing of a cartridge bearing and low mechanical and hydraulic losses, and the performance of a sealing in the same temperature range.

But no matter how perfect the theoretical and laboratory developments are, in such a responsible and innovative product as a new bearing assembly for a rolling stock the final word rests always with the running wear tests. To manufacture automation of these test beds, German companies Beckhoff and Bluemenbecker were involved. Bluemenbecker made the developed on the basis of classical hydraulic loaders, and Beckhoff, for the first time in civil engineering, used its unique high-precision multi-tonnage electrodynamic actuators for loading previously used only by NASA.

In , the test beds were certified for testing all types of railway bearings. The complex optimal geometry of the racers and rollers, along with the high demands for surface perfection and machine tools performance, is the basis for the requirements for the Performance Specification for the development of special grinding and superfinishing equipment by the world's leading machine tool manufacturers: Italian Mechanika Nova machine tools for internal and external grinding of several surfaces of racers simultaneously , as well as German Modler roller grinding and Nagel roller superfinishing.

Jointly with the Czech companies Roboterm and Hydroma, a modern energy-efficient induction heating and punching line for bearing racers has been developed, ensuring an optimal pattern of appearing of the metal fibres on the raceways. Technologies were also mastered and modern equipment was purchased for hard turning, superfinishing of racers, etc. After hundreds of thousands of kilometres of running on the raceways, working sides of the racers and the working surfaces of the rollers, including the convex working ends, required according to the test procedure, no signs of wear were found at all!

In this context, it is necessary to mention the unique development of the UPEC — an energy-efficient closed cylindrical bearing assembly of increased service life, HARP Duplex, intended for the modernization of cars of conventional load carrying capacity. A thousand cars with HARP Duplex bearing assemblies underwent the supervised operational tests in the Russian Railways, which resulted in 2 million km of run without any signs of wear!

Together with a new development — the plasma hardening of the bearing surfaces of the box - the box assembly with the HARP Duplex bearing now reliably ensures a repair-free run of thousand km or eight years without maintenance and is the optimal product for the modernization of cars of conventional load carrying capacity. Thus, the Ukrainian UPEC Industrial Group confidently entered the "elite world club" of the manufacturers of cartridge bearing assemblies of increased service life, steadily demonstrating a combination of age-old engineering traditions, its own innovative developments with the transfer of advanced European technologies.

Right grease has crucial importance for bearing productivity. Is provides thin film between contact areas in the bearing for friction reduction, heat spread and corrosion prevention on the balls and raceways. The grease will effect on maximal speed and temperature, rotational moment, level of noise, and finally, operation life of the bearing. There is a range of greases, depending on the area of application.

Mineral and synthetic grease are most often used and oriented for general and high-speed application. The micro-filter editions are used for low-noise applications. There are water resistant types for low or high temperatures. Silicon greases have wide temperature ranges and more stable viscosity when temperature reduces. They are also water resistant and safe for application with the majority of plastics and rubbers sealed rings etc. Perfluorochemical grease and grease PFPE are incombustible, compatible with oxygen and very stable to many chemicals.

Many of them have low pressure of evaporation and they are suitable for applying in vacuum. They are often applied for surface protection from sticking and frost-up due to high hydrophobic features. Dry greases are recommended to use where the standard grease can cause contamination, for example, in vacuum environments. Such grease as molybdenum disulfide and tungsten disulfide are applied on balls and raceways of bearings, provide smooth work and higher moving speed.

These coverings are resistant to water and diluted acid. They can be powder-like, wax-like and bonded coverings, which are applied with the help of solvent. Damping greases are widely applied in automotive components to prevent crackle and creaks. They also make switches and drives qualitative. They can be applied in slow rotating bearings, like in potentiometers.

Greases for food industry meet special sanitary demands. There are two types of greases for cases, where the contact with food is possible and the contact is absent. These greases are steady to washout and cleaning. Grease viscosity Oils with low viscosity and greases are applied, where the low grease performance is required, for example in sensitive tools. The greases with higher viscosity can be recommended for high-loaded, high-speed and vertical applications of shafts.

The greases with lower viscosity are preferred for high-speed applications, as they generate less heat. Though, greases often provide much bigger stability than oils, majority of modern greases with low rotational moment can create the indicators of rotational moment similar to oils according to features.

Many greases support their consistence in wide temperature range and they are easy for applying. The light instrument grease is used in components with very low rotational moment. These catches are often applied in high-speed tooth bearings with low rotational moment. Plastic greases are oils, which are mixed with thickener to stay inside the bearing.

They are usually suitable for high loads and have an evident advantage in providing constant greasing for a long time without technical maintenance. Grease quantity It is necessarily to take into account that big amount of grease may be harmful for bearing. The filling with grease will mean bigger resistance to rotation higher rotational moment , but still the risk of heating still remains.

The free space inside bearing is important for heat emanating from contact area between ball and raceway. As a result the grease excess can lead to premature destruction. Small percent can be indicated for high speed component with low rotational moment, while much bigger filling can be recommended for using with low speed and high load.

Inner diameter of bearing is 8 mm and outer — 22 mm. The above mentioned formula gives DN , so the grease should have factor higher than this number. Many modern consistent greases are suitable for high speeds with nominal 1 mln.

DN or more. In the modern world, virtually no production of equipment, machinery and vehicles can do without the use of bearings.

These are relatively small, but extremely important components. After all, the bearings provide the rotation of the shaft or axis, while reducing the energy loss. The highest requirements to the quality and strength of bearings are made in the field of agricultural machinery.

This is not surprising, if you recall in what difficult conditions agricultural machinery works. Dust, dirt, moisture, high temperatures and extreme loads during the season are just some of the difficulties waiting for agro-bearings. Almost seventy years of design and production experience allows the company to create one of the best bearings in the world.

Bearings of this line proved to be strong, reliable and wear-resistant. Their tightness and dimensional accuracy makes it possible to use these parts in units and agricultural equipment intended for extreme loads.
