New SKF super-precision cylindrical roller bearings series on show at EMO Milano 2015

SKF is launching two new super-precision cylindrical roller bearings series, which meet the machine tool industry’s demand for higher speed capability with low friction. The new bearings will be shown for the first time at EMO Milano 2015

Gothenburg, Sweden, 6 October 2015: SKF, the knowledge engineering company, is launching two new SKF super-precision cylindrical roller bearings series at EMO Milano 2015. 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 optimized 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 bearing are more suitable for heavier loads. Visitors to EMO Milano 2015 will get an exclusive first look at both of these new series, which will be available for order in 2016.”

The single row cylindrical roller bearings series is equipped with an outer ring centered cage, window-type, made of carbon fiber reinforced polyetheretherketone (PEEK). The reduced number of rollers, together with the optimized 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 80 mm.

The new single row series represents the optimal solution for applications like the non-tool end of a motorized spindle, where the requirement for higher speed outweighs that for higher rigidity, high-speed milling machines, high-speed machining centres, lathe electro-spindles.

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

SKF possesses extensive experience of specifying bearings for specific applications. The company will utilize 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.

EMO Milano 2015 takes place on 5-10 October 2015 in Milan, Italy. Visitors to the event will find SKF in Hall 3 at Stand L15-H16.
