Product Description

The INA KR30-X-PP-A is a compact cam follower with needle rollers, designed for track and cam applications where high radial loads and reliable guidance are required.

Key design features:

• Thick-walled outer ring for high radial load capacity
• Threaded stud instead of an inner ring, allowing easy mounting into plates or machine components
• Caged needle rollers, which:
• Prevent direct contact between rolling elements
• Reduce friction versus full-complement designs
• Enable higher speeds and lower heat generation

The PP sealing system on both sides provides effective protection against contamination and helps retain lubricant, extending service life. The cam follower runs on a flat counter-track rather than in a housing bore and can absorb axial loads due to misalignment in both directions.

Typical Applications

• Conveyor and material handling systems
• Linear guidance systems
• Cam and follower mechanisms
• Packaging and automation equipment
• General industrial machinery with track or rail guidance
