Cylindrical Roller Bearings FAG NJ319 -E-XL-TVP2

The NJ319 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager is a single-row support bearing measuring 95 × 200 × 45 mm, designed for high radial loads.

As a single-row roller bearing, the NJ319 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager can withstand very high radial forces. The cylindrical rollers create a broad line of contact with the raceway, which, compared to the point contact found in ball bearings, enables high rigidity. The open bearing has a bore of 95 mm, an outer diameter of 200 mm and a width of 45 mm. It has standard radial clearance and operates within a temperature range of -30 to +120 degrees.

What is the NJ319 -E-XL-TVP2 cylindrical roller bearing suitable for in practice?

The NJ319 -E-XL-TVP2 cylindrical roller bearing is primarily used where high radial forces act on rotating shafts and, at the same time, axial displacements in one direction need to be compensated for. The NJ design functions as a support bearing. The outer ring has two fixed flanges, whilst the inner ring has one fixed flange and is removable on one side. This enables the bearing to absorb axial forces from one direction. In the opposite direction, the design allows for changes in the shaft’s length without restriction.

What role do the TVP2 polyamide cage and tolerance class P0 play?

The TVP2 polyamide cage guides the rolling elements whilst being lightweight and dampens operating noise during operation. This material is suitable for the specified temperature range of –30 to +120 degrees. Manufacture to tolerance class P0 (equivalent to ABEC 1) complies with the standardised normal tolerance for industrial applications. Lubrication is provided by design via the surrounding housing, as the outer ring is designed without its own lubrication groove or bore.
