New super-precision cylindrical roller bearings series from SKFSKF is launching two new SKF super-precision cylindrical roller bearings series. Both of these new series deliver superior bearing performance compared with existing SKF offerings, accommodating higher speeds and lower friction as well as providing a variety of other operational benefits to the machine tool industry.

Mauro Merlo, SKF Super Precision Bearings Product Manager at SKF, explains: “The new SKF super-precision cylindrical roller bearings are optimised solutions for OEMs that require greater load-carrying capacity and higher speeds. While the SKF super-precision single-row cylindrical roller bearings have a higher speed capability, the SKF super-precision double-row cylindrical bearings are more suitable for heavier loads. Both of these new series will be available for order in 2016.”

The single-row cylindrical roller bearings series is equipped with an outer ring-centred cage, window-type, made of carbon fibre reinforced polyetheretherketone (PEEK). The reduced number of rollers, together with the optimised cage, enable the bearings to accommodate higher speed, attain lower operating temperature and lower friction. The range is suited for use where shaft diameters range from 40 to 80mm.

SKF’s new single row series is suitable for applications like the non-tool end of a motorised spindle, where the requirement for higher speed outweighs that for higher rigidity, high-speed milling machines, high-speed machining centres and lathe electro-spindles.

The new double-row super-precision cylindrical roller bearings series provides a balance between load-carrying capacity, rigidity and speed. This series allows higher speed capability in conventional high-stiffness belt-driven CNC lathe spindles. It features three integral flanges on the inner ring and no flanges on the outer ring. In addition, the series has an optimised internal geometry and a new glass fibre-reinforced, prong-type, roller-centred PEEK cage, which enables the bearings to accommodate higher speeds and minimises the amount of frictional heat generated. The range is suitable for shaft diameters from 25 to 130mm.

SKF possesses extensive experience of specifying bearings for specific applications. The company will utilise its advanced knowledge of the machine tool sector to support OEMs to evaluate the total cost of ownership and benefits of the new SKF super-precision series, ensuring the correct bearings are specified for the application.
