Ball bearings benefit from 30 per cent less friction

Paul Boughton

SKF is launching the new E2 family of energy-efficient performance class bearings that have been engineered and manufactured to reduce frictional moment by 30 per cent or more beyond the already efficient SKF standard bearings.

By exhibiting ultra-low friction, the new bearings enable equipment manufacturers to build greater energy efficiency into their equipment, thereby reducing the total cost of ownership for end users. Because the bearings are dimensionally interchangeable with ISO standard components, conventional bearings can be upgraded simply and quickly to reduce the energy consumption of existing equipment.

A variety of SKF E2 bearing types will be available off-the-shelf in common sizes, starting with single-row deep-groove ball bearings. These ultra-low friction bearings offer an excellent way to reduce mechanical friction in light-to-normal loaded applications, such as electric motors, pumps, and conveyors, thereby cutting energy consumption as a result.

Furthermore, as the new SKF E2 bearings run cooler than standard bearings at equivalent loads and speeds, additional benefits include longer grease life and extended relubrication intervals, which further reduces maintenance and ongoing costs.

SKF's family of energy-efficient bearings is designed for use in a wide range of industrial equipment, including motors, fans, pumps and gearboxes, in sectors ranging from renewable power generation to transportation.

SKF E2 tapered roller bearings are already available for automotive applications and E2 spherical and cylindrical roller bearings will be released later in 2009.
