Cylindrical Roller Bearings FAG NUP315 -E-XL-TVP2-C3

The FAG NUP315 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 75 × 160 × 37 mm, provides a robust fixed bearing solution for demanding industrial applications.

The single-row cylindrical roller bearing NUP315 -E-XL-TVP2-C3 is designed as an open roller bearing for high radial loads. Owing to its fixed-end design, this bearing guides the shaft in both axial directions and, in addition to high radial loads, also accommodates limited axial forces. With an inside diameter of 75 mm, an outside diameter of 160 mm and a width of 37 mm, the bearing is manufactured to the standard tolerance class P0/PN or ABEC 1.

What functions does the NUP315 -E-XL-TVP2-C3 cylindrical roller bearing perform as a fixed bearing?

This design is used where shafts need to be positioned axially whilst simultaneously withstanding high radial loads. Typical applications can be found in general mechanical engineering and in heavy-duty gearbox designs. The fixed bearing design, featuring flanges on the outer and inner rings as well as a loose flanged disc, restricts axial movement of the shaft within the housing and thus supports the concentricity of the entire assembly.

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

The version with the suffix TVP2 features a polyamide cage, which ensures quiet running and guides the rolling elements. The slightly increased radial clearance (C3) compensates for operational heating or tight fits. This ensures that the rotational movement remains smooth even within the temperature range of -30 to +120 degrees. As the bearing is of an open design, the choice of lubricant can be adapted to the specific operating environment.
