Cylindrical roller bearings
Overview

Cylindrical roller bearings from Western Bearing House

Cylindrical roller bearings use rollers in line contact with the raceways, which gives very high radial load capacity and stiffness. N, NU and NJ designs allow the shaft to move axially or locate it in one direction, and NN double row bearings suit high-stiffness applications.
