Cylindrical Roller Bearings SKF NU315 ECP

The SKF NU315 ECP cylindrical roller bearing, a single-row non-locating bearing measuring 75x160x37 mm, offers a high radial load-carrying capacity for demanding industrial applications.

This NU-type cylindrical roller bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from either side, facilitating installation and removal. The Explorer version features an optimised internal design that ensures even load distribution. Thanks to its open design without seals, the roller bearing is suitable for external lubrication circuits using oil or grease.

What is the NU315 ECP cylindrical roller bearing suitable for in operation?

This design accommodates high radial forces whilst simultaneously compensating for axial changes in shaft length. As the inner ring has no flanges, the shaft moves freely within the bearing during thermal expansion. Its use is recommended in bearing arrangements subject to high radial loads and thermal expansion. This floating bearing is not intended for purely axial loads, which is why it is usually combined with a separate fixed bearing.

What characteristics does the polyamide cage offer during assembly and in operation?

The suffix ECP denotes a polyamide cage and an optimised internal design. The cage guides the cylindrical rollers precisely and is characterised by its low weight and elastic running characteristics. The bearing is designed for operating temperatures ranging from -30 to +120 degrees. With dimensional accuracy to P0 and increased running accuracy to P6, the component meets defined requirements for concentricity and low-vibration operation.
