LR209-2RS

chmotion LR209-2RS Yoke Track Roller
Crowned Cam Follower Roller with 45mm Bore & 90mm OD

Key Advantages

• Robust construction: 45mm bore diameter with a substantial 90mm outer diameter for high rigidity.
• Superior sealing (2RS): Contact seals on both sides provide effective protection against dust and contaminants.
• Crowned outer ring (R=500): Distributes load evenly, reducing edge stress and preventing brinelling on tracks.
• High load capacity: Handles up to 15.2 kN dynamic (Fr) and 24.7 kN static (F0r) radial loads.
• Precision performance: Manufactured to P6 (ABEC-3) tolerance class for smooth, accurate linear motion.
