Cylindrical Roller Bearings FAG NJ2220 -E-M1

The NJ2220 -E-M1 cylindrical roller bearing, measuring 100 × 180 × 46 mm, serves as a support bearing designed to accommodate high radial loads and unilateral axial loads.

The FAG NJ2220 -E-M1 cylindrical roller bearing is a single-row rolling bearing designed to withstand high radial loads. As a support bearing of the NJ design, the inner ring guides the cylindrical rollers via a fixed flange and can be removed from one side. This allows for axial displacement in one direction. With a bore of 100 mm, an outer diameter of 180 mm and a width of 46 mm, this bearing is suitable for demanding industrial applications.

What is the NJ2220 -E-M1 cylindrical roller bearing suitable for in industrial applications?

This cylindrical roller bearing is particularly suitable for bearing positions in general mechanical engineering where high radial loads occur. As it is a support bearing, it absorbs not only the dominant radial forces but also axial guidance forces from one direction. The solid brass cage guides the rolling elements precisely and is designed for continuous operation. Thanks to its permissible temperature range of –30 to +150 degrees, the bearing copes with a wide range of thermal conditions.

What design features characterise the NJ2220 -E-M1 type?

The bearing has an open design without an integrated seal and an outer ring without a lubrication groove or bore. Lubrication and sealing must therefore be provided by the surrounding structure. As the inner ring can be removed from one side, the inner and outer rings can be mounted separately on the shaft and housing. The bearing has the standard radial clearance and a tolerance class of P0/PN or ABEC 1, which ensures smooth running during normal operation.
