Cylindrical Roller Bearings FAG NJ312 -E-XL-TVP2-C3

The FAG NJ312 -E-XL-TVP2-C3 cylindrical roller bearing (60x130x31 mm) withstands heavy radial loads whilst also providing single-sided axial guidance.

The NJ312 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing designed for industrial applications involving high loads. In the NJ version, the outer ring has two solid flanges and the inner ring has one solid flange. This design enables the bearing to function as a support bearing: it withstands radial loads, guides the shaft in the axial direction and internally compensates for changes in length in the opposite direction. With a bore of 60 mm, an outside diameter of 130 mm and a width of 31 mm, this FAG roller bearing provides a robust basis for compact shaft mountings.

In which applications is the NJ312 -E-XL-TVP2-C3 used?

This design is used where high radial forces act on the bearing location and axial guidance forces occur from one direction. As the inner ring is removable from one side, the inner and outer rings can be fitted separately. As an open bearing without an integrated seal, it is intended to be lubricated via the surrounding structure. The permissible temperature range is from –30 to +120 degrees Celsius.

What do the polyamide cage and the C3 clearance mean for this bearing?

The version with the suffix TVP2 features a polyamide cage which guides the cylindrical rollers, dampens running noise and has a low weight. The suffix C3 indicates an increased radial clearance compared to the standard. This additional clearance between the rolling elements and raceways compensates for thermal expansion during operation caused by heating or tight fits on the shaft and housing, and helps to prevent the bearing from becoming stressed.
