Cylindrical Roller Bearings FAG NU311 -E-XL-TVP2-C3

The FAG NU311 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 55x120x29 mm and a C3 clearance, provides a robust floating bearing arrangement for high radial forces.

The NU311 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing with standard tolerance P0/PN or ABEC 1. With a bore of 55 mm, an outer diameter of 120 mm and a width of 29 mm, this design can accommodate high radial loads. The cylindrical rollers create a broad line of contact on the raceways, ensuring high rigidity. The open bearing has no integrated seal and can be flexibly integrated into oil- or grease-lubricated assemblies.

What is the NU311 -E-XL-TVP2-C3 cylindrical roller bearing suitable for in operation?

As a floating bearing of the NU design, this version compensates for axial length changes directly within the bearing. The inner ring has no flanges and can be removed from both sides, allowing axial shaft movements to occur freely relative to the housing. Typical applications are found in mechanical and plant engineering at bearing locations that accommodate purely radial loads. Wherever no axial guiding forces are acting, this design allows for unimpeded length compensation of the shaft.

What properties do polyamide cages and C3 bearing clearance offer?

The designation TVP2 stands for a polyamide cage. This material reduces inertial forces and contributes to quiet running. The C3 design features a slightly increased radial clearance. This provides the necessary operating clearance in the event of tight fits or temperature differences between the inner and outer rings. With a permissible temperature range of -30 to +120 degrees, the bearing is designed for demanding thermal environmental conditions.
