Cylindrical Roller Bearings FAG NU219 -E-XL-TVP2-C3

The FAG NU219 -E-XL-TVP2-C3 cylindrical roller bearing, with a 95 mm bore and C3 radial clearance, offers a robust support solution for high radial forces.

The NU219 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With its main dimensions of 95 mm inner diameter, 170 mm outer diameter and 32 mm width, this open bearing can accommodate high radial forces. The NU design allows the inner ring to be removed from both sides. This facilitates the separate mounting of both bearing rings onto the shaft and housing.

In which installation scenarios does the NU219 -E-XL-TVP2-C3 cylindrical roller bearing prove its worth?

Used purely as a floating bearing, this design compensates for thermally induced changes in shaft length without any constraint. Typical applications include industrial gearboxes, electric motors, pumps and general mechanical engineering. As the bearing does not carry any axial forces, this bearing arrangement is usually combined with a separate fixed bearing. The integrated polyamide cage guides the cylindrical rollers quietly and is suitable for operating temperatures ranging from –30 to +120 degrees Celsius.

What is the function of the polyamide cage and the C3 bearing clearance?

The version with the suffix TVP2 features a lightweight polyamide cage, which reduces friction and moving masses within the bearing. At the same time, the increased radial clearance (C3) compensates for operational heating or tight fits. Without this increased operating clearance, the radial clearance could be reduced too much during operation. As this is an open bearing without an integrated seal, you should select the appropriate lubricant and external housing seal to suit the specific environment.
