Cylindrical Roller Bearings SKF NU310 ECP

The SKF NU310 ECP cylindrical roller bearing is a single-row non-locating bearing with a polyamide cage, designed for high radial loads with shaft diameters of 50 mm.

The SKF NU310 ECP cylindrical roller bearing, as a single-row rolling bearing, withstands high radial forces. The cylindrical rollers create a line-contact with the raceway, enabling the design to withstand high radial loads whilst providing rigid guidance. With dimensions of 50 mm bore, 110 mm outside diameter and 27 mm width, this open bearing without an integrated seal is used in industrial machinery that utilises an external lubricant supply.

What is the NU310 ECP cylindrical roller bearing suitable for in practice?

This rolling bearing is suitable for bearing arrangements subject to purely radial loads, where axial changes in shaft length must be compensated for. As the inner ring of the NU design is flangeless and removable from both sides, the unit functions as a classic non-locating bearing. Typical applications include industrial shaft mountings and rotating machine units. The SKF Explorer version features an optimised internal geometry for even load distribution during operation.

What are the advantages of the polyamide cage and the NU design?

The integrated polyamide cage reduces friction and noise whilst keeping the component weight low. The material design allows for an operating temperature range of –30 to +120 degrees Celsius. The separable inner ring facilitates installation in cases of tight fits on the shaft or housing. In terms of manufacturing, the rolling bearing has dimensional accuracy to tolerance class P0 (ABEC 1) and running accuracy to P6 (ABEC 3).
