LR50/8-2RS

chmotion LR50/8-2RS Double-Row Cam Roller
Compact Yoke Roller with 8mm Bore, 24mm OD & Crowned Running Surface

Key Advantages

• Crowned (R500) running surface: Reduces edge stress and ensures smooth, stable tracking on guide rails or cam paths.
• Double-row ball design: Provides superior load capacity and rigidity compared to single-row designs in a compact footprint.
• High dynamic load capacity: 4.3 kN (C) rating for demanding, high-cycle applications.
• Robust construction: Made from 100Cr6 bearing steel (AISI 52100) for durability and long service life.
• Wide operating temperature: -20°C to +120°C range with Shell Alvania EP2 grease for versatile use.
• High precision: P6 (ABEC-3) dimensional and runout tolerances for reliable, repeatable motion.
