Single Row Cylindrical Roller Bearings With Inner Ring 313221

Single Row Cylindrical Roller Bearings With Inner Ring 313221

The 313221 is a single row cylindrical roller bearing with a 240mm bore and 440mm outer diameter, built from sturdy chrome steel. It handles combined loads up to 353250 lbf and runs smoothly at speeds up to 2000 RPM.

Its brass cage keeps rollers centred for even load distribution, while the open design allows easy lubrication with grease or oil. The bearing operates well in temperatures from -30°C to 110°C.

With a weight of 82.2kg, it’s robust for heavy-duty applications like industrial gearboxes or large machinery. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements, being interchangeable with SKF bearings.

The 120mm width and 4mm chamfer ensure secure fitting, while the 11.3mm axial displacement tolerance offers flexibility in mounting. Ideal for scenarios requiring high radial load capacity and durability.
