LR208-X-2RS

chmotion LR208-X-2RS Heavy-Duty Yoke Track Roller
Cylindrical Cam Roller with 40mm Bore, 85mm OD & Double Seals (2RS)

Key Advantages

• High-load capacity: Handles 13.2 kN dynamic (Fr) & 22.7 kN static (F0r) radial loads for demanding applications
• Robust double-seal protection (2RS): Effectively retains grease and excludes contaminants for long service life in harsh environments
• Cylindrical running surface: Provides consistent, stable guidance and high rigidity in track and cam follower applications
• P6 (ABEC-3) precision: Ensures smooth, low-vibration operation with precise dimensional tolerances and radial runout
• Wide temperature range: Operates reliably from -20°C to +120°C (-4°F to +248°F)
