Cylindrical Roller Bearings FAG NJ315 -E-M1

The FAG NJ315 -E-M1 cylindrical roller bearing is a robust support bearing with a brass cage, designed for high radial loads, with dimensions of 75 x 160 x 37 mm.

The FAG NJ315 -E-M1 cylindrical roller bearing is a single-row roller bearing with a cylindrical bore, designed for demanding industrial applications. With a bore of 75 mm, an outside diameter of 160 mm and a width of 37 mm, the design is suitable for heavy-duty mechanical drives. The solid brass cage guides the cylindrical rollers precisely and resists vibrations. As an open bearing, this design can be filled with an application-specific lubricant. The component complies with tolerance class P0/PN or ABEC 1.

In which industrial applications does the NJ315 -E-M1 cylindrical roller bearing prove its worth?

This bearing is primarily used where high radial forces are present and, at the same time, axial forces need to be accommodated on one side. Typical applications include industrial drives and rotating assemblies subject to combined loads. Due to its design as a support bearing, the bearing compensates for changes in shaft length in one direction without restriction. The permissible temperature range extends from –30 to +150 degrees and covers standard thermal requirements in mechanical engineering.

What design features characterise the NJ design with a brass cage?

The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the inner ring to be removed from one side, facilitating the separate assembly of the shaft and housing. The solid brass cage ensures high stability under dynamic loads and is recommended for applications subject to vibration. As this is an open bearing without a groove or lubrication bore in the outer ring, an external housing seal and lubricant supply must be provided.
