Cylindrical Roller Bearings SKF NUP310 ECJ

The SKF NUP310 ECJ cylindrical roller bearing, measuring 50 × 110 × 27 mm, serves as a single-row fixed bearing for high radial loads.

As a single-row roller bearing, the SKF NUP310 ECJ cylindrical roller bearing can withstand very high radial loads. Thanks to its NUP design, this model locks a shaft axially in both directions, thereby performing the function of a conventional fixed bearing. With a bore of 50 mm, an outside diameter of 110 mm and a width of 27 mm, this open bearing fits into precision-machined housing designs.

For which bearing arrangements is the NUP310 ECJ cylindrical roller bearing suitable?

This bearing unit is used in bearing locations where high radial forces act and, at the same time, axial guidance of the shaft on both sides is required. As the outer ring has two fixed flanges and the inner ring has one fixed flange and one loose flange disc, the component absorbs axial guidance forces in both directions. This eliminates the need for a combination with additional axial bearings to fix the shaft in place.

What features do the NUP design and sheet steel cage offer?

The ECJ design combines an optimised internal structure with a sheet steel cage. The cage guides the cylindrical rollers and maintains a uniform spacing between them. With standard radial clearance, the bearing is designed for common fit conditions at operating temperatures ranging from -30 to +150 degrees. As an open design without its own seal, the component requires protection against contamination via the housing design.
