Idler with bearings roller RR-Bx

for conveyornitrileneoprene®

Overview
Finned rollers have grooves on the surface and are permanently bonded to a steel insert with the bearings held into place with snap rings. The grooves create less surface contact on the workpiece and allow dirt, debris and liquids to pass. Rollers are available in neoprene, nitrile and urethane materials with hardness ranging from 20 to 60 durometer. Supplied with standard bearings.
