Cylindrical Roller Bearings FAG NU315 -E-XL-M1-C4

The FAG NU315 -E-XL-M1-C4 cylindrical roller bearing, with a 75 mm bore, brass cage and C4 clearance, offers high load-carrying capacity for demanding radial applications.

This single-row NU315 -E-XL-M1-C4 cylindrical roller bearing from FAG is designed as a non-locating bearing. Thanks to the line contact between the rolling elements and the raceways, the design can accommodate high radial forces. With an internal diameter of 75 mm, an external diameter of 160 mm and a width of 37 mm, this open bearing is suitable for designs where external lubrication is provided.

What is the NU315 -E-XL-M1-C4 cylindrical roller bearing suitable for?

Due to the NU design, the inner ring can be removed from both sides. This allows the bearing to compensate for axial length changes of the shaft relative to the housing without constraint within the rolling elements. Typical applications are found in general mechanical engineering at bearing locations where high radial forces occur and the bearing functions purely as a non-locating bearing. The brass cage guides the rolling elements stably even under demanding operating conditions.

What characteristics does the C4 radial clearance offer in the NU315 -E-XL-M1-C4?

This design features a significantly increased radial clearance (C4), which exceeds the standard value. This increased radial clearance supports operation when temperature differences occur between the inner and outer rings or when there are tight fits between the shaft and housing. Furthermore, the rolling bearing covers a temperature range from -30 to +150 degrees, ensuring it remains functional even under thermal stress.
