LR5208-2Z

chmotion LR5208-2Z Crowned Cam Follower Roller
Double Row Yoke Track Roller with 40mm Bore & Crowned Outer Ring

Key Advantages

• High-load double row design: Handles demanding radial forces with 26 kN basic static load (C0) and 35 kN basic dynamic load (C) ratings.
• Crowned (crown) running surface (R=500): Compensates for misalignment and edge-loading, ensuring smooth travel and extended service life in track and guide applications.
• 2Z shields on both sides: Provides effective protection against dust and contaminants while maintaining low running torque.
• Precision P6 (ABEC-3) class: Ensures smooth, low-vibration operation critical for automation and material handling equipment.
• Proven material combination: Rings and balls made from 100Cr6/52100 bearing steel for durability, paired with a lightweight, low-friction PA66 (Nylon) cage.
• Direct INA replacement: Fully interchangeable with popular models INA LR5208-2Z and LR5208 KDDU, offering a reliable and cost-effective alternative.
