Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized cylindrical roller bearing manufacturer and custom cylindrical 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.

Single row cylindrical roller bearings, Double row cylindrical roller bearings Four row cylindrical roller bearings And all kinds of inch sizes roller bearings Used in heavy electric motor, machine tool main shaft, axletree axle box, diesel engine crank shaft and the gear box, automobile, tractor, etc. This type of bearings is separable.As their rollers linearly come into contact with inner ring and outer ring with less coefficient of friction, these bearings have verygood capacity of radial load,suitable for electric motors,automobiles, transmission shafts, gear shaftsand so on.Double row cylindrical roller bearings are good at the spindles of machine tools.
Cylindrical rollers have linear contact with the raceway,and the bearings can carry heavier load. Applications are found in situations characterized by heavy load and shock load and also high rotation speed.

Torrington heavy-duty cylindrical roller bearings are designed to provide the highest possible radial load capacity for a given cross section. Standard types consist of an inner and outer ring with cage containing a complement of rollers. Engineered roller profiles relieve end stresses to provide a more uniform distribution under demanding load and misalignment conditions.
Three basic styles are offered to meet different application requirements.
Single-row bearings are available in six standard types, all with a similar roller complement and radial load capacity. Either the inner or outer ring has two integral roller-guiding flanges. Designs with an additional flange can accommodate moderate thrust loads in one direction.
Two-row bearings have two complements of rolling elements for greater radial load capacity.
Four-row bearings provide extremely high radial capacity for heavy-duty roll neck applications in metal rolling mills. This design uses the highest-quality carburizing-grade bearing alloy steels to resist wear and shock under heavy rolling loads.
