Cylindrical Roller Bearings FAG NJ407

The FAG NJ407 cylindrical roller bearing, measuring 35x100x25 mm, withstands high radial loads and is designed to function as a single-sided support bearing.

The FAG NJ407 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With a bore of 35 mm, an outside diameter of 100 mm and a width of 25 mm, this design transmits high radial loads whilst ensuring reliable guidance. Fitted with a sheet steel cage and standard radial clearance, this design performs reliably in bearing arrangements subject to predominantly radial loads. You will receive an open bearing to tolerance class P0/PN or ABEC 1, suitable for a temperature range of -30 to +150 degrees.

For which loads is the NJ407 cylindrical roller bearing suitable?

This cylindrical roller bearing is particularly suitable for bearing arrangements subject to high radial loads, where low unilateral axial forces also occur. Design engineers prefer to use the NJ design in shaft bearings with single-sided guidance. Thanks to the line contact between the rollers and raceways, this design offers high radial load-carrying capacity and dimensional stability during continuous operation.

What function does the NJ design fulfil as a support bearing?

The designation ‘NJ’ defines the component as a support bearing with two fixed flanges on the outer ring and one flange on the inner ring. This allows the inner ring to be removed from one side, which facilitates the mounting of the rings onto the shaft and housing. The bearing guides the shaft in an axial direction and compensates for changes in length in the opposite direction without constraint. As this is an open bearing without a seal, the lubricant is supplied via the housing system.
