22208 CC/W33 40x80x23mm Double Row Spherical Roller Bearing With Lubrication Groove & Hole

1. Product Overview

22208 CC/W33 is standard metric double row spherical roller bearing, overall dimension 40×80×23mm, old model number 53508. CC stands for optimized symmetrical roller internal structure with pressed steel cage; W33 represents outer ring equipped with annular lubrication groove and three oil holes for convenient on-site re-lubrication. The spherical outer raceway features excellent self-aligning performance, tolerating up to 1.5° shaft misalignment and shaft deflection without extra friction rise. Double row spherical rollers carry heavy radial load and bidirectional axial load simultaneously, suitable for continuous heavy load, vibration and harsh dust industrial working conditions. Widely matched for industrial reducers, mine crushers, heavy conveyors, vibrating screens, construction machinery and paper making equipment.

3. Core Advantages

• CC optimized symmetrical roller structure, uniform load distribution, lower internal friction and longer service life under continuous heavy load
• W33 integrated lubrication groove and holes, supports periodic supplementary grease injection without disassembly, greatly reducing maintenance downtime
• Outstanding self-aligning characteristic, adapts to shaft misalignment, housing deformation and equipment vibration to avoid bearing premature failure
• Double row roller layout provides super strong radial load capacity, bears stable bidirectional axial thrust load at the same time
• High hardness wear-resistant steel rings and rollers, anti-fatigue, shock resistant, suitable for dusty mining and construction harsh environment
• Standard ISO metric interchangeable size, universal replacement for mainstream heavy machinery spare parts
• Multiple custom options: brass machined cage, C3 loose clearance, high temperature resistant grease, outer ring laser marking

4. Application Scenarios

• Mining & crushing equipment: Jaw crushers, cone crushers, vibrating screens, mine heavy belt conveyors
• Industrial transmission: Heavy duty gear reducers, speed reducers, large industrial gearboxes
• Construction machinery: Excavator auxiliary transmission parts, road roller walking assemblies, mixer rotating supports
• Paper & textile equipment: Paper machine drying rollers, heavy textile loom main shafts
• General heavy machinery: Large fan main shafts, grain processing equipment, lifting transport machinery

Fit OEM assembly and aftermarket replacement of heavy load, vibration-prone industrial rotating equipment.
