Cylindrical Roller Bearings SKF NUP305 ECP

The SKF NUP305 ECP cylindrical roller bearing, a single-row fixed bearing measuring 25x62x17 mm, offers a high radial load capacity.

The NUP305 ECP cylindrical roller bearing combines compact dimensions with high load-carrying capacity for demanding industrial applications. Thanks to the line contact between the rollers and raceways, this bearing can accommodate high radial forces. Designed as an open rolling bearing, it can be lubricated via the machine housing. The SKF Explorer version also features an optimised internal design, which is engineered to ensure even load distribution during operation.

In which bearing arrangements is the NUP305 ECP cylindrical roller bearing used?

Design engineers primarily use this bearing arrangement where high radial forces occur and axial fixation of the shaft is required at the same time. The NUP design has two fixed flanges on the outer ring, one fixed flange on the inner ring and a loose flange disc. This enables the bearing to accommodate axial forces from both directions and act as a fixed bearing. Typical applications include bearing arrangements with high radial loads and axial shaft guidance on both sides.

What are the distinctive features of this design and the polyamide cage?

The integrated polyamide cage (suffix ECP) is characterised by its low weight and good damping properties. It guides the rollers and is designed for an operating temperature range of –30 to +120 degrees Celsius. Dimensional accuracy complies with tolerance class Normal (P0/ABEC 1), whilst running accuracy is manufactured to class P6 (ABEC 3). During assembly, clean mating surfaces and suitable housing seals must be provided, as the outer ring is designed without a groove or lubrication bore.
