misalignment

Initial misalignment should not exceed .001 in./in. Any misalignment generates thrust forces between outer ring and flange or end plate. Excessive thrusting can lead to increased operating temperature and destruction of the seal in standard cam followers and yoke rollers. Where misalignment and outer ring thrusting cannot be avoided, RBC recommends crowned outer rings or the RBC Roller design which is more capable to withstand thrust loads.
