Through modern scientific management, excelsior products and technological design, advanced production tools and strict testing methods, we have produced various types of conveyance equipment. In 2001, we were certified by ISO9001: 2000, which has ensured the reliability and stability of product quality. Also, we have passed Germany DQS authentication in the domestic same trade. We have established long-term relationships with some famous mechanical manufacturers both at home and abroad, such as Veit GmbH, Hashima, Oshima, Summit, and KDK companies.

Roller bearings in general can be applied only where the angular misalignment caused by shaft deflection is very slight. This deficiency is not present in the spherical roller bearing. It has excellent load capacity and can carry a thrust component in either direction.
In the helical roller bearing, the rollers are wound from strips of spring steel, and afterwards are hardened and ground to size. If desired, the rollers can bear directly on the shaft without an inner ring, particularly if the shaft surface has been locally hardened. This bearing has been successfully applied under conditions of dirty environment.
Auburn manufactures thrust ball bearings in both round and ‘V’ groove styles. They can have open or enclosed style. These bearings are used in places where protection is needed from dust, dirt, water and foreign matter.

Roller bearings are selected by a process similar to that used for ball bearings. They must be chosen, however, in accordance with the recommendations given in the catalog of the manufacturer of the particular type of bearing under consideration.
Roller bearings are usually made of case-hardened steels. The carburized case or exterior should have a hardness of 58-63 Rc. The core is softer with a hardness of 25-40 Rc. Certain plain-carbon and alloy steels have been found suitable for roller bearing service. The maximum temperature is limited to about 350? F.
Designed for ease of mounting, Fafnir wide inner ring ball bearings carry radial, axial and combination loads. The assembly consists of a single-row ball bearing with an inner ring that extends on both sides for maximum shaft support. The extended inner ring slips onto the shaft and is attached by a self-locking collar or setscrew locking device. In either style, the bearing can be positioned easily on the shaft without shoulder, locknuts or adapters.
