LYC’s needle roller bearings have small axial section dimension, good rigidity and capacity to carry high radial loads, which are suitable for limited radial installing when positions. These are widely applied under working situation with swinging shaft and bearing housing. However, needle roller bearing can only carry pure radial load, but, can't prevent the axial displacement between shaft and bearing housing. In addition, the angle error for inner axle and outer axle is not allowed.
Equivalent Dynamic (Static) Load-Needle
In order to maintain bearings working in a good condition, a minimum load must be imposed on bearings, particularly on bearings working at high speeds, with high accelerations, or with the load direction changing frequently, because under these working conditions, inertial force of balls and cage and lubricant friction will have bad influence on the rotation of bearings, and detrimental sliding movement may be caused.
The minimum load of a needle roller bearing can be obtained from.：
Fmin = 0.02C

C-Basic dynamic loading rating, N
LYC’s needle roller bearings are supplied with a pressed steel cage, a machined solid cage or glass fiber reinforced polyamide 66 on other engineering plastics. The cages of materials are identified by a suffix, these suffix are explained in the chapter “LYC Bearing Designation”.
