Other salient points to be noted
• Ultimate static and impact loads should not exceed 150% of catalog rating.

* The nominal bore diameter is measured at the inner ring center.
** Clearance after shim pack compression.
*** Excessive clamping forces will cause loss of bearing clearance.
**** In cases where operating thrust load exceeds inner ring clamping force, engineering support is recommended.
