Cylindrical Roller Bearings FAG NU316 -E-M1

The FAG NU316 -E-M1 cylindrical roller bearing is a single-row non-locating bearing with a brass cage and main dimensions of 80 x 170 x 39 mm.

As a radial rolling bearing, the FAG NU316 -E-M1 cylindrical roller bearing is primarily designed to accommodate high radial loads. In the NU design, the bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which facilitates the separate assembly of both bearing rings. With standard radial clearance and tolerance class P0/PN or ABEC 1, the design covers a wide range of applications in industrial mechanical engineering.

What is the NU316 -E-M1 cylindrical roller bearing suitable for in mechanical engineering?

As a classic floating bearing, this roller bearing allows for the unrestricted compensation of axial length changes directly within the bearing. Typical applications include shaft mountings where temperature-induced expansion or manufacturing tolerances occur. Due to the line contact of the cylindrical rollers, this design is capable of transmitting greater radial forces than point-contact ball bearings. The solid brass cage guides the rolling elements even under vibrations and higher acceleration forces during operation.

What are the advantages of the brass cage in the NU316 -E-M1?

The designation letter M1 indicates a solid brass cage. This material is characterised by high strength and low friction relative to the steel rollers. Compared with standard sheet metal cages, the brass version is designed to withstand dynamic mass forces, shock loads and vibrations. As this is an open bearing without an integrated seal, the bearing location requires an external sealing system as well as a suitable lubricant supply for the permissible temperature range of -30 to +150 degrees.
