Cylindrical Thrust Roller Bearings

LYC’s cylindrical roller thrust bearings are divided into bearings of single row and double row. Single row cylindrical roller thrust bearings can carry axial load in one direction and limit axial displacement in one direction. Double-row cylindrical roller thrust bearings can carry axial load in both directions and limit axial displacements in both directions.


Minimum Load-Thrust Roller Bearings

In order to keep bearings working in a good condition, a minimum load must be imposed on bearings, particularly on bearings working at high speeds, 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 thrust roller bearing can be obtained from:

A £≠ Minimum load constant, see bearing dimension tables.
 
n £≠ Speed£¨r/min
 
Fr£≠ Radial load (when combined load), kN
 
C0£≠ Basic static load rating, kN

When bearings are started at low ambient temperatures or in the condition where the viscosity of lubricant is very high, a larger minimum load is required. Usually, the weight of the bearing supporting parts plus the load on the bearing have been over the minimum load. If the weight cannot be up to the minimum load, then extra radial load must be imposed on this type of bearing in order to meet the requirement of minimum load. The requirement can be met through preloading in axial with springs.
