LR5203-2RS

chmotion LR5203-2RS Yoke Track Roller (Cam Follower)
Double Row Crowned Roller with Integral Stud & Seals on Both Sides

Key Advantages

• Crowned (crowned running surface) outer ring: Superior guidance on rails and tracks, reduces edge stress, and compensates for minor misalignments.
• Sealed on both sides (2RS): Robust protection against contaminants like dust, dirt, and splashing liquids in demanding industrial environments.
• High load capacity: 13.4 kN maximum static radial load (F0r) and 9.3 kN dynamic load (Fr) for heavy-duty applications.
• Integral stud design: Ready-to-install with a 17mm bore and M12x1.5 stud thread (standard for LR52 series), eliminating the need for separate housings.
• Precision performance: P6 (ABEC-3) tolerance class ensures smooth, reliable motion with minimal runout.
