22×58×32mm Double Row Eccentric Cylindrical Roller Bearing GCr15 Chrome Steel for Cycloid Reducer

The 22UZ42117187T2 Eccentric Cylindrical Roller Bearing is a highly specialized precision component engineered specifically for cycloidal speed reducers and planetary gearboxes. It integrates an eccentric locking sleeve directly with the bearing inner ring, allowing the dual rows of parallel cylindrical rollers to generate a smooth orbital rotation. It is widely used in high-torque automated machinery where compact radial space, extreme structural rigidity, and massive radial load capacities are critical requirements.

• Integrated eccentric sleeve mechanism simplifies reducer assembly by unifying the eccentric shaft offset and the inner ring into one robust piece.
• Double-row cylindrical roller design provides massive linear contact area to withstand intense radial load spikes and alternating stresses.
• High rotational accuracy and low vibration minimize mechanical backlash, optimizing precision in servo-driven speed reducers.
• Premium hardened chrome steel delivers uniform material hardness (58–64 HRC) for prolonged rolling fatigue life.
• Optimized internal clearances prevent overheating and premature wear during continuous high-ratio orbital transmissions.

• 25+ years experience in industrial bearing manufacturing.
• Exported to 50+ countries worldwide.
• Rich experience in OEM & custom projects.
