Angular contact ball bearings and cylindrical roller bearings under load

Always bearing the opposite direction of the axial load, mounting angular contact ball bearings. Machine tool spindle angle contact ball bearing contact angle for 15 degrees and 25 degrees two kinds, Wind turbine bearing the contact angle of 15 degrees for high speed, axial load is small.

Cylindrical roller bearings can bear large radial load, can not bear the axial load. Single and double row cylindrical roller bearings, sealed angular contact ball bearing precision machine tool spindle is the most common cylindrical roller bearing inner hole with 1:12 taper double row cylindrical roller bearings NN30K (old code 3182) series.
