Cylindrical Roller Bearings FAG NUP2214 -E-XL-TVP2-C3

The FAG NUP2214 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 70x125x31 mm, serves as a fixed bearing for high radial loads and axial guidance on both sides.

The single-row cylindrical roller bearing NUP2214 -E-XL-TVP2-C3 can withstand high radial forces thanks to the line contact of the cylindrical rolling elements. In the NUP design, the bearing has two fixed flanges on the outer ring, one fixed flange on the inner ring and a loose flange disc on the opposite side. This enables the component to guide the shaft in both axial directions. The bearing is manufactured to the standard tolerance class P0/PN or ABEC 1.

What function does the NUP design fulfil in shaft guidance?

This fixed bearing is suitable for bearing arrangements where, in addition to high radial forces, alternating axial guiding forces also occur. Thanks to the single-row arrangement of the rollers, the installation space remains compact, with a width of 31 mm and an outer diameter of 125 mm. The NUP design enables a shaft to be guided axially in both directions without the need for separate axial bearing arrangements.

Why is the C3 radial clearance with a polyamide cage advantageous?

The design with a slightly increased radial clearance (C3) and a polyamide cage (TVP2) is suitable for operating conditions involving heat build-up or tight fits. The additional radial clearance compensates for thermal expansion during operation, ensuring that the rolling elements do not become stressed. The flexible polyamide window cage guides the cylindrical rollers with low sliding resistance and is designed for a temperature range of -30 to +120 degrees.
