LR5304-2RS

chmotion LR5304-2RS Double Row Cam Roller
Yoke-Type Track Roller with 20mm Bore, 62mm OD & High-Load Capacity

Key Advantages

• Double row design with 2RS seals: Enhanced load capacity and contamination protection for demanding applications.
• Exceptionally high load ratings: 22.2 kN dynamic load (C) and 24.57 kN maximum static radial load (F0r) for robust performance.
• P6 (ABEC-3) precision: Tight dimensional tolerances and radial run-out ensure smooth, accurate motion and extended service life.
• Optimized material selection: 100Cr6 bearing steel rings with a durable PA66 nylon retainer for strength and reduced friction.
• Ready for harsh environments: Pre-lubricated with Shell Alvania EP2 grease and operational from -20°C to +120°C.
