239/750 CAKCO83W509C3 Double Row Spherical Roller Bearing

239/750 CAKCO83W509C3 Double Row Spherical Roller Bearing

The 239/750 CAKCO83W509C3 is a double-row spherical roller bearing with a large 750mm bore and 1000mm outer diameter, built from tough chrome steel. It handles combined loads up to 1,379,877 lbf and runs smoothly at speeds up to 560 RPM.

Its brass cage and open design ensure durability while allowing easy lubrication through the 12mm holes. The tapered bore (1:12 ratio) provides a secure fit, and the C3 radial clearance accommodates thermal expansion.

This bearing suits heavy-duty applications like industrial gearboxes or mining equipment, where high radial loads and misalignment are common. It operates in temperatures from -30°C to 200°C.

Weighing 410kg, it’s built for robust performance. Compliant with RoHS and REACH standards, it’s interchangeable with SKF models for easy replacement. The lubrication groove (22.3mm wide) simplifies maintenance.
