  • Inch Size Tapered Roller Bearings - Schaeffler

    2019-5-24 · The axial load carrying capacity of the bearings is dependent on the nominal contact angle 0, Figure1. The greater this angle, the higher the axial load to which the bearing can be subjected. The size of the contact angle, and thus the load carrying capacity of the bearing, is indicated by the value e in the dimension tables.
