Stop Equipment Downtime with 21308 CC CA W33 Spherical Roller Bearings

Industrial machinery operators know the cost of unexpected bearing failure—hours of production lost, expensive repairs, and missed deadlines. When standard bearings can’t handle heavy radial loads or shaft misalignment, even the most reliable equipment grinds to a halt. Sourcing high-quality replacements with the right specifications often means long lead times or minimum order quantities that don’t fit urgent maintenance needs.

High Capacity Spherical Roller Bearings for Critical Machinery

The 21308 CC CA W33 Spherical Roller Bearing is engineered to solve these challenges. As a high capacity bearing designed for industrial machinery, it handles heavy radial loads and moderate axial loads while accommodating shaft misalignment—common in gearboxes, conveyors, and crushers. With ISO9001 certified production and a dedicated QC lab, we ensure each bearing meets P0-P4 precision standards, delivering consistent performance you can rely on.

Engineered for Demanding Industrial Conditions

This spherical roller bearing thrives in harsh operating environments where reliability is non-negotiable. Its double row roller design and aligning capabilities make it ideal for applications with heavy loads, variable speeds, and potential shaft deflection—such as in mining equipment and construction machinery. The W33 designation indicates a lubrication groove and three oil holes, ensuring efficient lubricant distribution even during extended operation, reducing wear and extending service life.

Technical Features That Maximize Performance

The 21308 CC CA W33’s performance is defined by critical technical parameters. Its 100mm bore diameter, 215mm outer diameter, and 47mm width provide a robust foundation for heavy-duty applications. Precision ratings from P0 (standard) to P4 (high precision) allow customization based on equipment requirements—P4 grade minimizes vibration in high-speed machinery, while P0 offers cost-effective reliability for general industrial use. Clearance options (C0, C3, C4) accommodate thermal expansion in high-temperature environments, preventing premature failure. Constructed from high-grade bearing steel, it delivers the durability needed to withstand continuous operation under heavy loads.

Why Genuine Bearings Reduce Total Cost of Ownership

Choosing authentic high capacity bearings over low-quality alternatives directly impacts your bottom line. Counterfeit bearings often fail prematurely due to substandard materials and poor manufacturing, leading to unplanned downtime, costly repairs, and potential damage to connected components. Our 21308 CC CA W33 bearings, backed by ISO14001 environmental certification, undergo rigorous testing to ensure load capacity and fatigue resistance. With a 12-month global warranty, we stand behind every product, reducing the risk of unexpected replacement costs and ensuring long-term reliability.
