LR208-2RS

chmotion LR208-2RS Yoke Track Roller (Cam Follower)
Single Row Cam Follower with Crowned Running Surface & Dual Seals

Key Advantages

• Robust load capacity: Handles up to 23.7 kN dynamic (C) and 14.1 kN static (C0) loads for demanding applications.
• P6 precision grade (ABEC-3): Ensures smooth, low-vibration operation and precise motion control.
• Premium material construction: Rings and balls made from 100Cr6 bearing steel for durability; PA66 nylon cage reduces friction.
• Effective dual-seal protection (2RS): Shields against contaminants like dust and moisture, extending service life.
• Crowned (crowned) outer ring profile (R=500): Compensates for misalignment and reduces edge loading for longer life on tracks or cams.
