Cylindrical Roller Bearings SKF NUP310 ECP

The SKF NUP310 ECP cylindrical roller bearing, with dimensions of 50x110x27 mm, offers high radial load-carrying capacity and axial guidance on both sides when used as a fixed bearing.

The NUP310 ECP cylindrical roller bearing is a single-row rolling bearing with an optimised internal design in SKF’s Explorer series. With a bore diameter of 50 mm, an outer diameter of 110 mm and a width of 27 mm, the design can accommodate high radial loads. The open bearing has no integrated sealing washers. Lubricants reach the rolling elements unhindered, whilst the surrounding machine housing provides protection against contamination.

In which applications does the NUP310 ECP cylindrical roller bearing handle radial and axial loads?

This cylindrical roller bearing is used where high radial loads occur and the shaft needs to be fixed in both axial directions at the same time. Thanks to the line contact between the cylindrical rollers and the raceways, the series can withstand high transverse forces. To ensure reliable operation, the permissible temperature range is designed to be from –30 to +120 degrees Celsius.

What is the function of the NUP design and the polyamide cage?

The NUP design features a fixed bearing with two fixed flanges on the outer ring, one fixed flange on the inner ring and a loose flange disc. This design secures the shaft axially on both sides. The integrated polyamide cage guides the rollers quietly and is characterised by its low weight. The bearing has standard radial clearance. In terms of dimensional accuracy, it complies with tolerance class P0/PN or ABEC 1, whilst its running accuracy is manufactured to P6 or ABEC 3.
