Cylindrical Roller Bearings FAG NU317 -E-XL-M1-C3

The FAG NU317 -E-XL-M1-C3 cylindrical roller bearing, measuring 85 × 180 × 41 mm, is a single-row non-locating bearing designed to withstand high radial loads.

The FAG NU317 -E-XL-M1-C3 cylindrical roller bearing is an open, single-row rolling bearing designed for demanding industrial applications. With a bore of 85 mm, an outside diameter of 180 mm and a width of 41 mm, the design is primarily intended to accommodate high radial loads. The inner ring can be removed from both sides, which facilitates the separate assembly of both bearing rings. Thanks to its brass cage and its design for temperatures ranging from -30 to +150 degrees, the bearing is suitable for demanding operating environments in mechanical engineering.

What is the NU317 -E-XL-M1-C3 cylindrical roller bearing suitable for?

In bearing arrangements subject to high radial forces, this roller bearing typically serves as a non-locating bearing. Due to its NU design, the bearing supports radial forces whilst freely compensating for thermally induced changes in shaft length within the bearing itself. As the outer ring has solid flanges and the inner ring is flangeless, axial displacements can be accommodated with low friction. Maintenance teams and design engineers alike rely on this design for heavy-duty mechanical drives.

What properties do the brass cage and C3 clearance offer in this design?

The designation M1 indicates a solid brass cage. Brass has good run-out properties and is suitable for applications involving vibrations or high accelerations. The designation C3 stands for a slightly increased radial bearing clearance. This internal clearance allows space for the rolling element ring when the bearing rings expand during operation due to tight fits or temperature differences. When designing the system, it should be noted that this open bearing operates without seals and therefore requires external sealing of the housing environment.
