Cylindrical Roller Bearings FAG NJ2215 -E-XL-TVP2

The FAG NJ2215 -E-XL-TVP2 cylindrical roller bearing (75x130x31 mm) withstands high radial loads and supports shafts axially in one direction.

The FAG NJ2215 -E-XL-TVP2 cylindrical roller bearing is a single-row bearing with an inner diameter of 75 mm, an outer diameter of 130 mm and a width of 31 mm. Thanks to its design featuring two flanges on the outer ring and one flange on the inner ring, this version serves as a support bearing. The design accommodates radial forces and supports axial forces on one side. The open bearing has standard radial clearance and operates within a temperature range of -30 to +120 degrees.

When is the support bearing design used in the NJ2215 -E-XL-TVP2 cylindrical roller bearing?

This design is suitable for bearing arrangements that primarily absorb radial loads whilst simultaneously guiding the shaft in an axial direction. Thanks to the inner ring being removable from one side, the bearing allows for axial length changes in the opposite direction, which helps to prevent stress concentrations in the machine housing.

Typical applications are found in bearing arrangements with combined guiding forces. As the outer ring is designed without a groove or lubrication bore, lubricant is supplied via the surrounding structure.

What are the key features of the TVP2 cage and its tolerances?

The TVP2 polyamide cage guides the rolling elements with low friction and quietly, which keeps dynamic mass forces to a minimum during operation. In conjunction with tolerance class P0/PN or ABEC 1, the rolling bearing fits into standard mechanical engineering fit systems.

As an open bearing, the bearing housing requires external seals to protect against contamination. During assembly, care must be taken to ensure the removable inner ring is correctly aligned so that the axial support acts in the intended direction of force.
