Double Row Full Complement Cylindrical Roller Bearings 319430 B-2LS

The 319430 B-2LS is a double-row cylindrical roller bearing with a 150mm bore and 210mm outer diameter, built for combined loads. Made from durable chrome steel, it handles radial loads up to 108900 lbf and runs smoothly at 1000 RPM.

Its full-complement design (no cage) maximises roller count for higher load capacity, while the sealed construction keeps contaminants out. The bearing works in temperatures from -30°C to 110°C and accepts grease or oil lubrication.

Ideal for heavy machinery like gearboxes or industrial equipment where space and load demands are critical. Compatible with SKF bearings for easy replacement. The snap ring grooves (DIN 471 standard) ensure secure outer ring positioning during operation.

With a width of 80mm, it’s compact for its load rating. Compliant with RoHS and REACH standards for safe use in regulated environments.
