Cylindrical Roller Bearings FAG NU2219 -E-XL-TVP2-C3

The FAG NU2219 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 95 × 170 × 43 mm, is designed to accommodate very high radial loads as a separable idler bearing.

The NU2219 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial rolling bearing for industrial applications subject to heavy radial loads. Thanks to the line contact of the cylindrical rollers, this design offers high radial load-carrying capacity and rigidity. FAG manufactures this model in tolerance class P0/PN (ABEC 1) as an open bearing without an integrated seal, allowing the choice of lubricant to be flexibly adapted to the specific design.

What is the NU2219 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

It is primarily used in bearing arrangements where high radial forces must be accommodated. The NU design functions as a non-locating bearing. As the inner ring has no flanges and can be removed from both sides, the bearing compensates for axial length changes in the shaft caused by thermal expansion without any internal constraint. Furthermore, the fact that it can be dismantled allows the inner and outer rings to be fitted separately.

What do ‘C3’ bearing clearance and a polyamide cage mean in this design?

The suffixes define specific characteristics for demanding operating conditions. The C3 designation indicates a slightly increased radial clearance. This additional radial clearance prevents the rolling elements from jamming if heating or tight fits reduce the operating clearance during operation. The TVP2 cage is made of polyamide. It guides the rollers quietly, reduces inertial forces and is designed for an operating temperature range of -30 to +120 degrees Celsius.
