Product Description

The INA KR30X NMT is a compact cam follower with needle rollers, designed for use on flat or profiled tracks. It features a cylindrical running surface and a thick-walled outer ring, allowing it to handle high radial loads in demanding applications.

Instead of an inner ring, this cam follower has a solid threaded stud, which makes mounting straightforward using the supplied hexagon nut. The internal needle rollers are guided by a cage, which:

• Prevents metal-to-metal contact between rollers
• Reduces friction compared with full-complement designs
• Allows higher rotational speeds and reduced heat generation

The internal geometry allows the cam follower to absorb axial loads due to misalignment in both directions. It is not mounted in a housing bore; instead, it runs against a flat counter-track or cam surface.

Typical Applications

• Conveyor systems
• Linear guide systems
• Cam and follower mechanisms
• Packaging and automation machinery
• Material handling equipment
