Double Row Full Complement Cylindrical Roller Bearings 319448 B-2LS

The 319448 B-2LS is a double-row cylindrical roller bearing with a 240mm bore and 320mm outer diameter, built from tough chrome steel. It supports combined loads up to 214200 lbf and works well in temperatures from -30°C to 110°C.

Its full-complement design (no cage) maximises roller count for higher load capacity, while the sealed construction keeps contaminants out. The bearing comes pre-lubricated for grease or oil systems.

This model fits applications like heavy machinery or industrial gearboxes where space is limited but high radial loads are present. It’s interchangeable with SKF bearings for easy replacement.

With a 95mm width and snap ring grooves (DIN 471 compliant), installation is straightforward. RoHS and REACH compliant for safe use in various industries.
