The 22230 CC/W33 is a spherical roller bearing with specific design features. Here’s a detailed breakdown:
గోళాకార రోలర్ బేరింగ్ 22230 CC/W33 Specifications:
Bearing Type: గోళాకార రోలర్ బేరింగ్ (Self-aligning, double-row rollers)
ISO Dimension Series: 22230 (follows ISO 15:2011 standard)
22: Series code (heavy-duty, wide inner ring)
2: Width series (medium)
30: Bore diameter = 150 mm (30 × 5 = 150 mm)
CC Design:
Enhanced roller guidance (improved internal geometry for better load distribution)
Machined brass cage (CC-type) for higher strength and temperature resistance
W33: Indicates a lubrication groove and three lubrication holes in the outer ring for improved grease supply.
Key Dimensions (ISO Standard):
Bore Diameter (d): 150 mm
Outer Diameter (D): 270 mm
Width (B): 73 mm
Load Ratings (Typical Values, Confirm with Manufacturer):
Dynamic Load Rating (C): ~1,050 kN
Static Load Rating (C₀): ~1,400 kN
Speed Limit (Grease/Oil Lubrication): Varies by lubrication method (~2,000 rpm for oil, lower for grease)
Features & Applications:
Self-Aligning: Compensates for misalignment (shaft/ housing deflection or mounting errors).
High Load Capacity: Suitable for heavy radial and moderate axial loads.
W33 Lubrication: Enables efficient relubrication in harsh conditions.
Common Uses: Industrial gearboxes, mining equipment, paper mills, crushers, and heavy machinery.
Equivalent Bearings (Cross-Reference):
SKF: 22230 CCK/W33
FAG/NSK/NTN: Similar designations (may vary slightly by cage material).
Timken: Often labeled under the same ISO code.
Maintenance Tips:
Relubricate periodically (follow manufacturer guidelines).
Ensure proper alignment during installation.
Check for wear, overheating, or vibration in service.
