LR5004-2RS

chmotion LR5004-2RS Double-Row Cam Follower Roller
High-Precision Yoke Track Roller with Crowned Running Surface & Double Seals

Key Advantages

• Crowned (convex) outer ring: Minimizes edge stress for smoother operation and extended life on misaligned or curved tracks.
• Double-sealed (2RS) design: Integrated contact seals on both sides provide superior protection against dust, debris, and moisture in harsh environments.
• Exceptional load capacity: Handles up to 11.28 kN maximum static radial load (F0r) and 7.9 kN dynamic radial load (Fr) for demanding applications.
• High-precision performance: P6 (ABEC-3) tolerance class ensures consistent, reliable motion with minimal runout.
• Rugged construction: Features rings and balls made from 100Cr6 bearing steel (SAE 52100) for high durability and fatigue resistance.
