Reduce Downtime with High Capacity Spherical Roller Bearing 21308 CC CA W33
Industrial machinery operators know the cost of unexpected downtime—hours of halted production, missed deadlines, and expensive repairs. Many face this issue due to bearings that fail prematurely under heavy loads or misalignment. Sourcing reliable replacements with flexible order quantities and quick delivery often adds another layer of frustration.
Engineered for Heavy-Duty Performance and Quick Availability
The Spherical Roller Bearing 21308 CC CA W33 addresses these challenges with its high capacity design and our streamlined supply chain. As a professional bearing manufacturer with decades of experience, we offer this precision-grade bearing (available from P0 to P4) with a 1-piece MOQ for standard orders, ensuring you can secure critical replacements without overstocking. Our automated production lines and in-house testing facilities guarantee consistent performance, whether for gearboxes in manufacturing plants or heavy-duty agricultural equipment.
Optimal Performance in Demanding Conditions
This Spherical Roller Bearing excels in applications with heavy radial loads and moderate axial loads, thanks to its double-row roller design and aligning capability. It accommodates shaft misalignment up to 2 degrees, making it ideal for industrial machinery operating in harsh environments—such as textile mills with variable shaft positioning or construction equipment exposed to constant vibration. The W33 designation indicates a lubrication groove and three holes in the outer ring, ensuring efficient grease distribution for extended service life in high-temperature or dusty conditions.
Key Technical Features That Matter
Precision and durability start with critical specifications: The 21308 CC CA W33’s 100mm bore diameter, 215mm outer diameter, and 47mm width provide a robust foundation for heavy loads. Its P0-P4 precision grades control dimensional accuracy, reducing noise and vibration in high-speed applications. Clearance options (C0, C3, C4) allow customization for thermal expansion needs—C3 clearance, for example, suits applications with significant temperature fluctuations. Constructed from high-grade bearing steel, this bearing delivers the stability required for continuous operation in industrial machinery, where component failure can halt entire production lines.
Why Genuine Bearings Lower Total Cost of Ownership
Choosing genuine Spherical Roller Bearings over counterfeit alternatives directly impacts your bottom line. Counterfeit bearings often use substandard materials, leading to early fatigue and failure—costing far more in downtime and repairs than the initial savings. Our bearings meet ISO, ABMA, and DIN international standards, backed by strict incoming material inspections and full-process quality control. With a 12-month warranty, we stand behind every product, ensuring you avoid the hidden costs of frequent replacements and unplanned maintenance.
