LR5303-2RS

chmotion LR5303-2RS Yoke Track Roller (Cam Roller)
Double Row Sealed Roller with 17mm Bore & 52mm OD for High-Load Applications

Key Advantages

• Double row design with 2RS seals: Enhanced load capacity and superior protection against contaminants
• High-load performance: 13.7 kN static load (C0) & 19.1 kN dynamic load (C) for demanding cycles
• Crowned running surface (R500): Compensates for misalignment, reducing edge stress
• P6 (ABEC-3) precision: Tight dimensional tolerances and radial runout for smooth, accurate motion
• Robust construction: 100Cr6 bearing steel rings and PA66 nylon retainer for durability
