Flange-Mount Specifications

The Self-Aligning Flange Mount Bearing assemblies combine the ±5° self-alignment with the low profile of the self-clinching bearing in a steel flange. The two bolt-hole flange allows the bearing application design to be oriented in either direction. Using steel
flanges allows special profile flange designs to be easily incorporated.

Flange-Mount Features:

Multiple bearing choices
Low Profile
Special Flange Design / Manufacture Service
Non-Align option available
