LR50/7-2RS

chmotion LR50/7-2RS Yoke Track Roller
Double-Row Cam Follower with 7mm Bore, 22mm OD & Crowned Running Surface

Key Advantages

• Crowned (arcuate) outer surface: Reduces edge stress and ensures smooth tracking on guide rails or cam paths.
• Double-contact seals (2RS) on both sides: Provides effective protection against contaminants and grease leakage.
• High load capacity: Robust design supports up to 3.3 kN dynamic load (C) and 1.7 kN static load (C0).
• Precision P6 (ABEC-3) grade: Ensures smooth, low-vibration operation for accurate motion control.
• Pre-lubricated and ready to install: Filled with Shell Alvania EP2 grease for immediate service.
