SKF’s sealed energy efficient deep groove ball bearing, sealed E2 DGBB, reduces friction by more than 30%. It is suitable for applications in industries ranging from electric motors and two-wheelers to industrial conveyors and water pumps. The product is part of the SKF BeyondZero portfolio. This concept looks into environmental aspects such as material selection, energy efficiency and reduction of lubricant leakage. To be included in the BeyondZero portfolio, products, services and solutions must deliver significant environmental benefits.
“This bearing is a good example of a sustainable solution that saves energy in many different applications. Our products meet the needs of many of our energy saving programmes implemented worldwide,” says Luigi Cavallero, business development manager: powertrain, electrical and two wheeler, SKF.
The sealed E2 DGBB reduces friction by more than 30% compared to the SKF Explorer sealed DGBB. As a result the product significantly saves energy and reduces CO2 output. The new feature, compared to the previously launched E2 performance class of bearings, is the addition of a seal that provides minimal interference between the inner ring and seal lip without compromising the performance of the sealing ability.
For a typical textile machine running 8000 hours per year equipped with 200 sealed E2 DGBBs, the reduction is estimated to be 11 310 kWh annually. This translates into a CO2 saving of 8,5 tons a year according to a world power grid mix CO2 factor of 0,749 kg CO2e/kWh. The bearing is available in different sizes up to 52 mm outer diameter.
