LR5003-2RS

chmotion LR5003-2RS Double Row Cam Follower Roller
Heavy-Duty Yoke Track Roller with Crowned Surface & Integral Seals

Key Advantages

• Double-row design with crowned (R500) outer ring: Distributes load evenly for high capacity and compensates for minor misalignments, ensuring smooth tracking on guides and cam paths.
• Integrated seals on both sides (2RS): Provide superior protection against contaminants like dust and splashes, extending bearing life in demanding environments.
• High dynamic load capacity: Supports up to 5.4 kN (Fr) for reliable performance under significant operational stresses.
• Precision P6 (ABEC-3) grade: Offers tight dimensional tolerances and low radial run-out for consistent, accurate motion.
• Optimized for cam & track systems: The crowned profile and robust construction make it ideal for following complex motion profiles with minimal friction.
