Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized tapered roller bearing manufacturer and custom tapered roller bearings designer of various kinds of conveyors, belts, pulleys, bearings, rollers, bushings and so on. 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.

The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing.This conical geometry is used as it gives a larger contact patch, which permits greater loads to be carried than with spherical (ball) bearings, while the geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs. This avoids rapid wear and greatly reduces rolling friction.The rollers are guided by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.

Tapered Roller Bearings used primarily exposed to radial load based joint radial and axial load, the general should not alone bear the axial load. Bearing such design
makes the Inner Ring Road surface, the outer ring road roller and roller rolling surface of the cone surface at the apex of the intersection of the center line of bearings 1:00. In addition to the metric system product line, there are many Imperial family. Applicable to withstand shocks and heavy-duty load. Tapered Roller Bearings separate bearings addition, there are dual bearings, pairs two joint bearings and four bearings.
It is mainly used to support of radial and axial combine load, in which axial load is more than radial. Its capacity depends on the angle of outer ring raceway, the bigger the angle the larger the capacity. Tapered roller bearings are widely used in industries, such as, automobile, mill machine, mine, metallurgy and plastic industry.
