Product Description

The INA KR30-B-NMT is a compact cam follower with needle rollers, designed for use on flat or profiled tracks. Instead of an inner ring, it uses a solid threaded stud, allowing for easy mounting into machine components with a simple through-hole and nut.

A thick-walled outer ring enables the cam follower to withstand high radial loads, while the internal needle rollers with cage provide:

• Controlled rolling element guidance
• Reduced friction compared to full complement designs
• Higher permissible speeds and lower heat generation

The design also allows the cam follower to absorb axial forces caused by misalignment in both directions.

Typical Applications

• Conveyor and material handling systems
• Linear guidance systems
• Cam drives and indexing mechanisms
• Automation and packaging machinery
