Cylindrical Roller Bearings FAG NJ2208 -E-XL-TVP2-C4

The FAG NJ2208 -E-XL-TVP2-C4 cylindrical roller bearing, with dimensions of 40x80x23 mm, can accommodate high radial loads with increased C4 clearance.

The NJ2208 -E-XL-TVP2-C4 cylindrical roller bearing is a single-row rolling bearing from the FAG range. With a bore of 40 mm, an outer diameter of 80 mm and a width of 23 mm, the bearing accommodates high radial forces. In the support bearing version, the outer ring has two fixed flanges and the inner ring has one fixed flange, which supports axial guidance forces in one direction. The bearing is manufactured in an open design without seals.

In which installation scenarios does the NJ2208 -E-XL-TVP2-C4 cylindrical roller bearing accommodate axial forces?

The support bearing version is suitable for designs where, in addition to significant radial loads, single-sided axial guidance is required. In the opposite direction, axial displacement is permitted, which compensates for thermal length changes in the shaft. As the inner ring can be removed from one side, the inner and outer rings can be fitted separately. The polyamide cage guides the cylindrical rollers and ensures low-vibration operation.

What are the key characteristics of the combination of a polyamide cage and C4 clearance?

The significantly increased radial clearance (C4) prevents the rolling elements from jamming when there are considerable temperature differences between the inner and outer rings, or when tight fits reduce the operating clearance. The TVP2 polyamide cage is characterised by its low weight, which reduces inertial forces during operation. The component has an operating temperature range of -30 to +120 degrees. The open design without an integrated seal eliminates the need for lubrication holes in the outer ring and integrates the lubrication supply into the surrounding structure.
