Cylindrical Roller Bearings FAG NJ2212 -E-XL-TVP2-C3

The FAG NJ2212 -E-XL-TVP2-C3 cylindrical roller bearing, with a 60 mm bore, polyamide cage and increased C3 bearing clearance, offers high radial load-carrying capacity as a support bearing.

The NJ2212 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG Rolling Bearings with main dimensions of 60x110x28 mm. Due to the line contact between the cylindrical rollers and the raceways, this design can withstand very high radial loads. In the NJ design, the bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows it to support shafts in the axial direction, whilst the inner ring remains removable from one side on the opposite end.

What is the NJ2212 -E-XL-TVP2-C3 cylindrical roller bearing suitable for as a support bearing?

This bearing is used where assemblies must primarily carry high radial loads whilst simultaneously accommodating axial forces from one direction. Due to its support bearing function, the component guides the shaft axially on one side and allows axial displacement in the opposite direction. This design is particularly suitable for shaft mountings subject to thermally induced changes in length. The open design without an integrated seal allows for direct lubrication via the housing.

What do ‘polyamide cage’ and ‘C3 clearance’ mean in relation to this bearing?

The designation letter TVP2 stands for a polyamide cage, which ensures quiet running and low friction. The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This additional bearing clearance helps to prevent the rolling elements from seizing up if the rings expand due to heat build-up during operation or tight fits. The permissible temperature range is from -30 to +120 degrees Celsius.
