22210 CC/W33 50x90x23mm Double Row Self-Aligning Spherical Roller Bearing With W33 Lubrication Groove

1. Product Overview

22210 CC/W33 is standard metric double row spherical roller bearing with overall dimension 50×90×23mm. CC refers to optimized symmetrical spherical roller design with stamped steel cage for uniform load distribution; W33 means outer ring is equipped with circumferential lubrication groove and three oil injection holes for convenient periodic grease replenishment without disassembly. Spherical outer raceway delivers excellent self-aligning performance, allowing 1.5° shaft deflection and installation misalignment without abnormal friction and heat. Double row spherical rollers bear heavy radial load and bidirectional axial load simultaneously, shock resistant and stable under continuous vibration, dust and heavy-duty working conditions. Widely used in industrial heavy reducers, mine crushers, vibrating screens, heavy belt conveyors, construction mixers and paper making machinery.

3. Core Advantages

• CC symmetrical roller design disperses pressure evenly, reduces internal friction and extends service life under long-term heavy alternating load
• Built-in W33 lubrication groove and oil holes support on-site supplementary lubrication, greatly cutting equipment maintenance downtime
• Superior self-aligning capability compensates shaft deflection, housing deformation and assembly misalignment to avoid early bearing failure
• Double row roller layout provides outstanding radial bearing capacity, stable to withstand two-way axial thrust loads at the same time
• High toughness bearing steel rings and rollers, good anti-fatigue and anti-shock performance, adapt to dusty mining and construction harsh environments
• Standard ISO metric interchangeable dimension, universal replacement for mainstream heavy industrial machinery spare parts
• Customizable options: brass machined cage, C3 loose clearance, high-temperature anti-oxidation grease, outer ring laser marking

4. Application Scenarios

• Mining & crushing equipment: Jaw crushers, cone crushers, vibrating screens, mine heavy conveyors
• Industrial transmission equipment: Heavy-duty gear reducers, large speed reduction boxes
• Construction machinery: Concrete mixers, road roller walking assemblies, excavator auxiliary transmission shafts
• Paper & textile machinery: Paper machine drying rollers, heavy loom main spindles
• General heavy equipment: Large industrial fans, grain processing machines, lifting transport equipment

Suitable for OEM assembly and aftermarket replacement of heavy-load, vibration-prone industrial rotating machinery.
