239/500 CAK/C3W33 Double Row Spherical Roller Bearing

239/500 CAK/C3W33 Double Row Spherical Roller Bearing

The 239/500 CAK/C3W33 is a double-row spherical roller bearing with a large 500mm bore and 670mm outer diameter, built from tough chrome steel. It handles combined loads up to 667008 lbf and runs smoothly at speeds up to 950 RPM.

Its brass cage and open design ensure durability, while the tapered bore (1:12) simplifies installation. The bearing operates in temperatures from -30°C to 200°C and requires regular lubrication.

With a C3 radial clearance, it accommodates thermal expansion in heavy-duty applications. The lubrication groove (22.3mm wide) and holes (12mm) make maintenance straightforward.

Weighing 130kg, this robust bearing suits industrial machinery like crushers or large gearboxes. It’s interchangeable with SKF models and complies with RoHS and REACH standards.
