23056 CACK/C4W33 Double Row Spherical Roller Bearing

23056 CACK/C4W33 Double Row Spherical Roller Bearing

The 23056 CACK/C4W33 is a double-row spherical roller bearing with a 280mm bore and 420mm outer diameter, crafted from robust chrome steel. It handles combined loads up to 392741 lbf and operates smoothly at speeds up to 1600 RPM.

Its brass cage ensures durability, while the open design allows for easy lubrication through the 9mm holes. The bearing performs well in temperatures ranging from -30°C to 200°C.

With a tapered bore (1:12 ratio), it fits securely on shafts, and the C4 radial clearance offers flexibility under heavy loads. Ideal for industrial machinery like gearboxes or heavy-duty equipment where high radial and axial loads are present.

Weighing 52.5kg, it’s built for demanding applications. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements, interchangeable with SKF bearings.
