LR5000-2RS

chmotion LR5000-2RS Crowned Cam Follower Yoke Roller
Double-Row Sealed Track Roller with 10mm Bore & Crowned Running Surface

Key Advantages

• Precision crowned outer ring (R500 profile): Ensures smooth, consistent contact and reduces edge stress in track and guide applications.
• Integrated yoke design with through-bore: Ready for immediate mounting with a bolt or pin, simplifying assembly.
• Robust double-row ball complement: Provides high load capacity and stable operation under combined loads.
• 2RS contact seals on both sides: Effective protection against contaminants while retaining grease, ideal for demanding industrial environments.
• High-speed capability: Limiting speed of 9,000 r/min for dynamic applications.
• Direct INA LR5000-2RS replacement: Fully interchangeable, ensuring easy integration into existing designs.
