Maximum permissible axial load for Cylindrical Roller Bearings

For Cylindrical roller bearings to have a stable axial-load carrying capacity,

     ○When axial loads are applied, radial loads must also be applied

        (Axial load should be under approximately 40% of Radial load.)

     ○Sufficient lubricant must exist between the roller end faces and ribs.

     ○Superior extreme-pressure grease must be used.

     ○Sufficient running-in should be done.

     ○The mounting accuracy must be good.

     ○The radial clearance should not be more than necessary.

 
In cases where the bearing speed is extremely slow, the speed exceeds the limiting speed by more than 50%, or the bore diameter is more than 200mm,

careful study is necessary for each case regarding lubrication, cooling, etc.

In such a case, please consult with NSK.
