Cylindrical Roller Bearings FAG NU2317 -E-XL-M1-C3

The FAG NU2317 -E-XL-M1-C3 cylindrical roller bearing, measuring 85x180x60 mm, provides a heavy-duty, non-locating bearing for high radial loads in industrial applications.

The NU2317 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for mechanically demanding applications. Cylindrical rolling elements transmit high radial forces via line contact whilst maintaining high rigidity. The specified dimensions are 85 mm inner diameter, 180 mm outer diameter and 60 mm width. As an open roller bearing without sealing rings, the component can be integrated into on-site lubrication systems for a temperature range of –30 to +150 degrees.

In which applications is the NU2317 -E-XL-M1-C3 cylindrical roller bearing used as a non-locating bearing?

This radial cylindrical roller bearing is primarily suitable for designs subject to predominantly radial loads, where thermal expansion of the shaft needs to be accommodated. The NU design serves purely as a non-locating bearing: The outer ring guides the rolling elements between two flanges, whilst the inner ring is flangeless and can be removed from both sides. This allows axial displacement to occur freely within the bearing. Designers utilise this property in bearing arrangements subject to high radial loads and thermal changes in shaft length.

What is the function of the brass cage and the C3 clearance in this bearing?

The designation M1 indicates the version with a brass cage. This material withstands high accelerations, shock loads and vibrations. The classification in bearing clearance group C3 indicates a slightly increased radial bearing clearance. This additional clearance prevents stress build-up should temperature differences occur between the inner and outer rings, or should tight fits restrict the operating clearance. The bearing is manufactured to tolerance class P0/PN or ABEC 1.
