23038 KMC W33 Double Row Spherical Roller Bearing

23038 KMC W33 Double Row Spherical Roller Bearing

The 23038 KMC W33 is a double-row spherical roller bearing with a 190mm bore and 290mm outer diameter, built from sturdy chrome steel. It handles combined loads up to 205925 lbf and runs smoothly at speeds up to 2400 RPM.

Its spherical roller design adjusts to misalignment, while the steel cage ensures durability. The tapered bore (1:12) allows for secure mounting on shafts, and the open design simplifies lubrication.

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 17.5kg, it’s robust for demanding environments. Compliant with RoHS and REACH standards, it’s interchangeable with SKF bearings for easy replacement.
