Tandem Angular Contact Ball Bearings as Innovative for Final Drive Units

The final drive units designed today contain almost exclusively tapered roller bearings for supporting securely the highly loaded pinion shafts. Only recently, an innovative type of bearing support, the tandem angular contact ball bearing, has been developed. It allows the combination of high rigidity and long rating life with low friction. Schaeffler demonstrates that efficiency can be significantly improved through the use of tandem angular contact ball bearings. The improvement is an effect of the low-friction and low-temperature running of the tandem angular contact ball bearings. These characteristics become ultimately noticeable in reduced CO2 emission and fuel consumption in the classification of vehicles types. Easy mounting and safe installation preload round out the product characteristics.
