NJ217 Cylindrical roller bearing 85x150x28mm

The NJ217 is a cylindrical roller bearing with an 85mm bore diameter, 150mm outside diameter, and 28mm width. This NJ-series design features a single inner ring rib and two outer ring ribs, allowing axial displacement in one direction to accommodate thermal expansion or misalignment.

Cylindrical roller bearings are commonly used in electric motors, gearboxes, machine tool spindles, and industrial pumps where high radial load capacity and moderate to high speeds are required. The line contact between rollers and raceways provides excellent load distribution for heavy radial loads.
