Cylindrical Roller Bearings SKF NUP309 ECP

The SKF NUP309 ECP cylindrical roller bearing, measuring 45x100x25 mm, is designed as a fixed bearing for high radial loads and axial guidance on both sides.

The NUP309 ECP cylindrical roller bearing is a single-row roller bearing in the SKF Explorer design. It features an optimised internal design for even load distribution across the cylindrical rollers. Thanks to the NUP design, this rolling bearing guides the shaft in both axial directions. The open design without integrated seals allows for flexible lubricant selection via the housing. The bearing has standard radial clearance and is designed for a temperature range of -30 to +120 degrees Celsius.

What functions does the NUP309 ECP cylindrical roller bearing perform as a fixed bearing?

The NUP design fixes a shaft axially at both ends whilst simultaneously withstanding very high radial forces. Two fixed flanges on the outer ring, as well as one fixed flange and one loose flange disc on the inner ring, enable this guidance. The bearing is suitable for designs that require precise axial shaft positioning under heavy radial loads.

What is the function of the polyamide cage in the ECP version?

The suffix ‘ECP’ denotes an optimised internal design in combination with a polyamide cage. This cage guides the rollers at a uniform distance and, due to its low weight, reduces the moving masses. The polyamide material dampens running noise and limits the bearing’s operating range to temperatures between –30 and +120 degrees Celsius.
