SKF 22326 K C3 W33 Spherical Roller Bearing | Tapered Bore | High Load Capacity 130x280x93mm
The SKF 22326 K C3 W33 is a premium self-aligning spherical roller bearing engineered for demanding industrial environments characterized by heavy radial and axial loads, shock loading, and significant misalignment. The 223 series design utilizes two rows of rollers, providing superior load distribution and ensuring maximum lifespan even under continuous operation in harsh conditions. The 'K' designation signifies a 1:12 tapered bore, allowing for precise mounting onto a tapered shaft journal or via an adapter sleeve (not included), optimizing the interference fit necessary for high-speed and vibration-heavy applications. Furthermore, the 'C3' internal radial clearance is greater than standard, accommodating thermal expansion, high temperatures, and shaft deflection common in heavy machinery.
Optimized for reliability and reduced total cost of ownership (TCO), this bearing features the critical 'W33' suffix, which denotes an annular groove and three equally spaced lubrication holes in the outer ring. This design significantly facilitates continuous re-lubrication from a central system, extending service intervals and preventing premature failure due to lubricant breakdown. Typical applications include critical machinery such as heavy-duty gearboxes, crushers, vibrating screens, large industrial fans, and pulp and paper processing equipment where operational uptime is paramount. Choosing the 22326 K C3 W33 ensures maximum resilience and stability across its entire operational envelope.
