Overview
SKF KRE40PPA Track Roller is a rolling bearing whose thick outer ring rolls directly on a cam track, guide rail, or rocker arm contact surface. The needle- or cylindrical-roller assembly inside the heavy outer ring tolerates shock load and vibration, with yoke-type (bore + external pin) and stud-type (integral threaded shaft) variants covering most mounting configurations.
The outer ring is intentionally heavy so it can run directly against a track surface, with a cage of needles or cylindrical rollers inside. Yoke-type rollers mount on a separate pin or bolt-shaft; stud-type rollers carry an integral threaded stud and install as a single part.
Key features
- Outer-ring rotation tolerant of shock and vibration
- Heavy outer ring for direct track / rail contact
- Yoke-type (bore mount) and stud-type (integral shaft) variants
- Sealed or shielded options for contamination and lubrication control
Typical applications
- Cam followers and indexing mechanisms
- Guide tracks in packaging, printing, and textile machinery
- Rotating guide rollers on assembly and conveyor lines
- Automatic door and feed guides in machine tools
Selection guidance
Consider mounting style (yoke vs stud), outer-ring profile (cylindrical or crowned), track surface hardness, load direction and speed, and lubrication / sealing requirements.
