Cylindrical Roller Bearings FAG NU315 -E-M1

The FAG NU315 -E-M1 cylindrical roller bearing is a single-row idler bearing with a 75 mm bore, designed for high radial loads at temperatures up to +150 °C.

The NU315 -E-M1 cylindrical roller bearing is a single-row rolling bearing with the main dimensions 75 x 160 x 37 mm (bore x outer diameter x width). As a NU-type idler bearing, it has two fixed flanges on the outer ring, whilst the inner ring is flangeless and can be removed from both sides. This design accommodates purely radial forces and compensates for axial length changes in the shaft directly within the bearing. Fitted with a brass cage and standard bearing clearance, this open bearing is suitable for demanding industrial applications.

What is the NU315 -E-M1 cylindrical roller bearing suitable for?

This single-row cylindrical roller bearing is suitable for bearing arrangements subject to high radial loads, where the shaft is subject to heat-induced length changes relative to the housing. Thanks to the NU design, the inner ring moves axially freely relative to the roller set. It is primarily used in shaft bearings subjected to purely radial loads. As the bearing is open at both ends, you can integrate it directly into an existing housing lubrication system using oil or grease.

What are the distinctive features of the brass cage in the NU design?

The solid brass cage (suffix M1) guides the cylindrical rollers and is characterised by high strength under dynamic loads or vibrations. Compared with sheet metal cages, brass proves particularly effective under demanding operating conditions and at varying speeds. The bearing is designed for a temperature range of -30 °C to +150 °C. This non-locating bearing cannot accommodate axial forces and is usually combined with a suitable locating bearing on the shaft.
