22308K C3 W33 Double Row Spherical Roller Bearing

22308K C3 W33 Double Row Spherical Roller Bearing

The 22308K C3 W33 is a double-row spherical roller bearing with a 40mm bore and 90mm outer diameter, crafted from robust chrome steel. It handles combined loads up to 34845 lbf and reaches speeds of 8000 RPM, making it suitable for demanding applications.

Its spherical roller design accommodates misalignment, while the steel cage ensures durability. The C3 radial clearance allows for thermal expansion, and the open design simplifies lubrication through the built-in groove and holes.

This bearing operates in temperatures from -30°C to 200°C, ideal for heavy machinery or industrial gearboxes. Weighing 1kg, it’s a sturdy yet manageable component. Compliant with RoHS and REACH standards, it’s interchangeable with SKF models for easy replacement.

The tapered bore (1:12) ensures a secure fit, and the lubrication groove (6mm wide) makes maintenance straightforward. A reliable choice for high-load, high-speed environments.
