Bearings  of special purposes

We supply bearings of all classes of accuracy according to special technical specifications for special purposes (ETY 100, ETY 500, TY 3706, TY 3739, TY 4477, TY4479) and in accordance with GOST 520 (with an outer diameter from 20 up to 2300 mm of all design groups), TY37.006.107 and others.

Bearings as per the technical requirements of GOST 520 of following design groups:

Radial thrust bearings:

  • closed ball double-row
  • single-row tapered (metric and inch versions)
  • single-row tapered, without inner ring
  • single-row tapered with the flange on the outer ring
  • single-row tapered with a contact angle of greater than or equal to 20 degrees
  • doublerow tapered
  • closed double-row tapered

Roller and radial bearings with short cylindrical rollers:

  • without flanges on the outer ring
  • single flange on the outer ring
  • without flanges on the inner ring
  • single flange on the inner ring
  • single flange on the inner ring and with a flat stop ring
  • single flange on the inner ring and shaped resistant ring

Special bearings are used in rotating elements of aircraft devices, helicopters, sputniks sea vessels, auto transport, gas turbines and so on. The quality of the bearings corresponds to European standards. Also, unique bearings are being developed even by world standards.

Time dictates the requirements for the carrying capacity of bearing. This element of design of engine of aircraft invisible to the consumer of air services bearing must overcome the friction force in stressful conditions: to rotate billions of times without collapsing for a long period of time.

In the process of manufacturing  the rings and rolling elements, the production uses bearing, heat-resistant and stainless steel. Steel, bronze and aluminium alloys, brass, textolite and other materials are used for cages. In 2007, the production of hybrid bearings with ceramic rolling elements matured.

Miniature bearings

They are used for electric motors of domestic and industrial use, dental equipment, control and measuring equipment, automation and robotics.

Bearings of this group include precision radial and angular contact instrument bearings with flange and without it, with different classes of accuracy, with many designs of cages, shields and rubber seals.
