23188 CA/W33 Double Row Spherical Roller Bearing

23188 CA/W33 Double Row Spherical Roller Bearing

The 23188 CA/W33 is a double-row spherical roller bearing with a large 440mm bore and 720mm outer diameter, built from tough chrome steel for heavy-duty use. It handles combined loads up to 1,397,188 lbf and runs smoothly at speeds up to 850 RPM.

Its brass cage and open design allow for easy lubrication, with grooves and holes (22.3mm wide, 12mm diameter) to ensure proper oil flow. The bearing operates in temperatures from -30°C to 200°C, making it versatile for harsh environments.

The spherical roller design compensates for misalignment, while the double-row construction boosts load capacity. It’s interchangeable with SKF bearings, ideal for replacements in industrial gearboxes or mining equipment.

Weighing 365kg, it’s built for stability in large machinery. Compliant with RoHS and REACH standards, it’s a reliable choice for heavy industrial applications.
