Self-Align Specifications

The ±5° static Self-Aligning Bearing feature compensates for bearing mounting misalignment allowing the shaft to freely rotate.  Productivity gains in assembly and component machining are a direct result of incorporating Self-Aligning Bearings into a design.  In addition, longer bearing life and enhanced equipment performance can be directly attributed to the Self-Aligning feature.

Self-Aligning Bearing Features:

• No requirement for accurately positioned bearing mounting holes
• Trouble-Free OEM machine assembly
• Smooth shaft rotation with minimal start-up torque
