Cylindrical Roller Bearings FAG NJ222 -E-XL-TVP2

The FAG NJ222 -E-XL-TVP2 cylindrical roller bearing, measuring 110 × 200 × 38 mm, serves as a single-row support bearing for high radial loads.

The NJ222 -E-XL-TVP2 cylindrical roller bearing from FAG Rolling Bearings, as a single-row roller bearing, can withstand very high radial forces. With a bore of 110 mm, an outer diameter of 200 mm and a width of 38 mm, this roller bearing is suitable for highly loaded shaft mountings. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the bearing supports the shaft in the axial direction and allows for axial length compensation in the opposite direction.

What function does the NJ design fulfil in the NJ222 cylindrical roller bearing?

In shaft mountings subject to predominantly radial forces, the bearing acts as a support bearing thanks to its design. It guides the shaft in the axial direction and absorbs the guiding forces occurring there. At the same time, the internal axial displacement compensates for operational thermal length changes in the shaft. The inner ring can be removed from one side, which facilitates the separate mounting of the inner and outer rings onto the shaft and housing.

What are the key features of the TVP2 version with a polyamide cage?

The suffix TVP2 denotes a polyamide window cage, which guides the rollers with low mass and low noise. The permissible temperature range is from –30 to +120 degrees. As an open bearing, this model has no integrated seals, meaning that lubricating oil or grease is applied directly to the rolling elements. Manufactured with standard radial bearing clearance and tolerance class P0 (ABEC 1), the design is suitable for standardised mounting conditions.
