Cylindrical Roller Bearings FAG NJ240 -E-M1

The FAG NJ240 -E-M1 cylindrical roller bearing (200 × 360 × 58 mm) is a single-row support bearing with a brass cage, designed for high radial loads and single-sided axial guidance.

The FAG NJ240 -E-M1 cylindrical roller bearing is designed for industrial applications where very high radial loads occur. Its main dimensions are a bore diameter of 200 mm, an outside diameter of 360 mm and a width of 58 mm. As a single-row rolling bearing, this design features line contact between the cylindrical rollers and the raceways. This enables a high radial load-carrying capacity within compact dimensions.

What is the NJ240 -E-M1 cylindrical roller bearing suitable for?

This radial roller bearing is particularly suitable for shaft mountings where, in addition to dominant radial forces, axial guidance forces from one direction are also present. The NJ design acts as a support bearing and allows axial displacement of the shaft in the opposite direction without restriction. For assembly, the inner ring can be removed from one side, which facilitates the separate fitting of the inner ring and roller set onto the shaft and housing.

What is the function of the support bearing design and the brass cage?

The combination of the NJ geometry and the solid brass cage M1 provides mechanical stability under heavy loads. The brass cage guides the cylindrical rollers and withstands vibrations and dynamic forces. The bearing has the standard tolerance P0/PN (corresponding to ABEC 1) and standard radial clearance. As this is an open design without an integrated seal and without a groove or lubrication bore in the outer ring, lubrication is provided by the surrounding structure within a temperature range of -30 to +150 degrees.
