Cylindrical roller and groove is line contact bearings, radial load capacity, namely applicable to under heavy load and impact load, also suitable for high speed rotating N type and NU type fuel outlet can axial movement and can adapt by thermal expansion or installed by the error of shaft and the shell relative positions of the change, the most adapt to the NJ bearing type used for freedom and NF type can withstand some degree of one-way axial load, NH type and the NUP type can withstand some degree of to bi-directional load inner circle or their cups are separable for easy installation NNU NN type and the type of the radial direction load of strong rigidity.

Mostly for spindle is mainly used to keep frame: stamping steel maintains a (Z shape), copper alloy cutting system maintains a, pin type maintains a, synthetic resin forming maintains a.

Main application: medium and large motor, generator, internal combustion engines, combustion turbine, spindle, slow, device, loading/unloading machine, various industrial machinery.

Entity type needle bearing: within circle of the bearing basic structure and NU type fuel outlet cylindrical roller bearing the same, but due to the needle, the volume can be narrowed, and can withstand the big radial direction load without inner circle bearing the has an appropriate precision and hardness of the shaft of the mounting surface as a groove surface use.

Mainly used to keep frame: stamping steel maintains

 
Main application: automobile engine, transmission, pump, excavators crawler wheel, hoist, bridge crane, compressor.
