Established in 1998, China Xiaowei Bearing Co., Ltd. is a high-tech enterprise specializing in cylindrical roller bearing manufacturer and design many kinds of bearings. We have a modernized staffs of tech research and fog machine development, ISO9001 certificated, and manufacturing adopts advanced domestic and foreign standards such as GB, API, JIS, DIN, BS, NF and ANSI.

Made from clean bearing steel, Single-Row Cylindrical Roller Bearings are available 164 sizes in design variants NU, NJ, and NUP. Bearing cages are offered in roller-guided and outer ring-guided versions and are made from brass and polyamide. Optimized geometries of raceways and rolling elements maximize loading capacity, while modified cage design facilitates formation of lubricant film. Misalignments can be compensated through modified contact geometry and crowned inner raceways.
The new roller bearings are available in 164 sizes in design variants NU, NJ and NUP. The bearing cages are available in roller-guided and outer ring-guided versions and are made from brass and polyamide, with pressed steel versions available soon. In addition to radial clearance groups CN (C0) as standard, C3 and C4 groups are also available. Special versions, for example traction motor bearings (SQ1), wheel set bearings (SQ2) and electrically insulated bearings (SQ77) are available at short lead times.

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.
