Cylindrical Roller Bearings SKF NU1009 ECP

The SKF NU1009 ECP cylindrical roller bearing offers high radial load-carrying capacity with compact dimensions of 45 × 75 × 16 mm for demanding industrial applications.

The SKF NU1009 ECP cylindrical roller bearing is a single-row roller bearing with an optimised internal design. The component has a bore of 45 mm, an outside diameter of 75 mm and a width of 16 mm. Thanks to the modified line contact between the cylindrical rollers and the raceway, this design can withstand high radial loads. The integrated polyamide cage guides the rolling elements precisely and ensures low-vibration operation of the bearing assembly.

In which applications does the NU1009 ECP cylindrical roller bearing prove its worth?

This cylindrical roller bearing is primarily used where predominantly radial loads occur and axial length changes in the shaft need to be compensated for. As a floating bearing of the NU design, the component has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the shaft to move relative to the bearing housing with low friction in both axial directions, which effectively counteracts stresses caused by thermal linear expansion.

What are the key characteristics of the polyamide cage and the inner ring?

The polyamide cage is characterised by its low weight and good damping properties. The permissible temperature range extends from –30 to +120 degrees Celsius, making the bearing suitable for a wide variety of thermal environments. Furthermore, the inner ring can be removed from both sides, which significantly simplifies the separate assembly of the inner and outer rings. As an open rolling bearing without an integrated seal, the lubrication can be specifically adapted to the surrounding system.
