22238 CKJ Double Row Spherical Roller Bearing

22238 CKJ Double Row Spherical Roller Bearing

The 22238 CKJ is a double-row spherical roller bearing with a 190mm bore and 340mm outer diameter, built from sturdy chrome steel. It handles combined loads up to 301694 lbf and operates smoothly at speeds up to 2400 RPM.

Its spherical roller design allows for slight misalignment, while the steel cage ensures durability under heavy loads. The open construction requires regular lubrication for optimal performance.

This bearing is interchangeable with SKF models, making it a practical choice for replacements. Suitable for industrial machinery like gearboxes or crushers where high radial loads and misalignment occur.

Weighing 35.5kg, it’s robust for demanding applications. Compliant with RoHS and REACH standards, it works in temperatures from -30°C to 200°C.
