24188 ECA/W33 Double Row Spherical Roller Bearing

The 24188 ECA/W33 is a double-row spherical roller bearing with a large 440mm bore and 720mm outer diameter, built from tough chrome steel. It handles combined loads up to 1,748,339 lbf and runs smoothly at speeds up to 450 RPM.

Its brass cage and spherical rollers provide durability, while the open design allows easy lubrication through the 12mm holes. The bearing operates in temperatures from -30°C to 200°C, making it versatile for harsh conditions.

With a standard radial clearance (CN) and interchangeable with SKF models, it’s a reliable choice for heavy-duty replacements. Ideal for industrial machinery like crushers or large gearboxes where high radial loads are common.

Weighing 445kg, it’s robustly built for long-term use. Compliant with RoHS and REACH standards for safe handling. The lubrication groove (22.3mm wide) ensures consistent performance.
