Cylindrical Roller Bearings FAG NJ307 -E-XL-TVP2-C3

The FAG NJ307 -E-XL-TVP2-C3 cylindrical roller bearing (35x80x21 mm) withstands high radial loads and serves as a support bearing with single-sided axial guidance.

The NJ307 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for demanding industrial applications. In the NJ design, the outer ring has two fixed flanges, whilst the inner ring is removable on one side. This design enables the transmission of high radial forces whilst simultaneously accommodating axial guidance forces from one direction. The open bearing, which has no integrated seal, is designed for external lubrication within the housing.

What functions does the NJ design perform under radial and axial loads?

The NJ design is suitable for bearing arrangements with predominantly radial loads where additional axial guidance is required. Through its support bearing function, the NJ design fixes components in one axial direction, whilst the axial displacement in the opposite direction compensates for thermal expansion. The permissible temperature range extends from -30 °C to +120 °C for typical industrial environments.

What are the benefits of the polyamide cage and the C3 clearance?

The TVP2 design features a lightweight polyamide cage that guides the rollers quietly and reduces friction. The design is complemented by C3 bearing clearance. This increased radial clearance reduces the risk of stress when tight shaft fits are selected or when temperature differences occur between the inner and outer rings during operation. The outer ring has no groove or lubrication bore and complies with tolerance class P0/PN or ABEC 1.
