Cylindrical Roller Bearings FAG NJ2208 -E-M1

The FAG NJ2208 -E-M1 cylindrical roller bearing is a single-row support bearing with a brass cage, designed for shafts with a 40 mm bore, an 80 mm outer diameter and a 23 mm width.

The NJ2208 -E-M1 cylindrical roller bearing can withstand very high radial loads due to the line contact of its rollers. In the NJ version, the bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. Consequently, the design supports the shaft in one axial direction, whilst allowing for axial movement in the opposite direction. The open bearing, without sealing washers, is suitable for operation in oil- or grease-lubricated housings at temperatures ranging from –30 to +150 degrees Celsius.

What loads can the NJ2208 -E-M1 cylindrical roller bearing accommodate?

This single-row radial roller bearing is primarily designed to support shafts subjected to high radial loads and unilateral axial forces. Typical applications include bearings in general mechanical engineering with axial guidance in one direction only. As the inner ring can be removed from one side, the bearing rings can be fitted one after the other when the shaft and housing assemblies are separate. The fixed flange on the inner ring acts as a support bearing, meaning that additional components for axial fixation in this direction are not required.

What are the distinctive features of the version with a brass cage?

The variant with a brass cage is characterised by high dimensional stability under demanding operating conditions. Brass withstands vibrations and shock loads and guides the cylindrical rollers precisely. In this model, the manufacturing accuracy corresponds to the standard tolerance class P0 (ABEC 1), combined with standard radial bearing clearance. The outer ring is manufactured without a groove or lubrication bore, so that the lubricant is supplied via the interior of the housing.
