Bearing tolerances and clearances
- Tolerances: Normal, P6, P5
- Internal clearance: Single row track rollers, Double row track rollers
Yoke track roller (Cam roller) LR6003-2RS, single row, seals on both side, crowned running surface
chmotion LR6003-2RS Crowned Track Cam Follower
Yoke Type Track Roller with 17mm Bore, 40mm OD & Double-Sided Seals
Key Advantages
High radial load capacity: 5.9 kN max dynamic (Fr) and static (F0r) load rating for robust performance
Effective sealing (2RS): Contact seals on both sides for reliable protection against contaminants
Durable construction: Rings and balls made from 100Cr6 bearing steel for extended service life
Direct INA replacement: Fully interchangeable with popular INA LR6003 series models (e.g., LR6003 NPPU, LR6003-2RSR)
Crowned (arcuate) outer ring: Compensates for misalignment and ensures smooth, stable linear motion
