Cylindrical Roller Bearings SKF NUP220 ECP

The SKF nup220-ecp cylindrical roller bearing, with an outer diameter of 180 mm and a polyamide cage, offers a robust solution for high radial loads.

The nup220-ecp cylindrical roller bearing provides users with an open rolling bearing for demanding industrial applications. The design accommodates high radial forces and, thanks to the integrated flanges on the inner and outer rings, also supports the shaft axially in both directions. With a width of 34 mm and a cylindrical bore, the bearing unit can be fitted precisely into surrounding housing structures. SKF manufactures this version with standard radial clearance for normal operating conditions in mechanical engineering.

In which applications is the nup220-ecp cylindrical roller bearing used?

This rolling bearing is particularly suitable for mounting positions in general mechanical engineering where high radial forces are present. Thanks to the NUP design, the bearing acts as a fixed bearing capable of absorbing axial forces in both directions. Typical applications include industrial drives and gearbox units subject to combined loads. The permissible temperature range extends from –30 to +120 °C, enabling the bearing to cope with a wide thermal range during normal plant operation.

What is the function of the polyamide cage?

The lightweight polyamide cage guides the cylindrical rollers with low friction and contributes to an even load distribution within the rolling element ring. Compared to solid metal cages, the elastic plastic material reduces the moment of inertia and minimises noise during rotation. As this is an open design without integrated sealing washers, you can flexibly select lubricants such as grease or oil to suit the operating conditions and lubrication intervals of your design.
