An extended range of SKF Explorer tapered roller bearings – increased load ratings
Continuous improvements in manufacturing have made it possible to qualify a majority of the tapered roller bearing assortment in the standard rolling bearings catalogue to the SKF Explorer performance class. This includes all the previous TQ line items and a large number of additional items, mainly due to new rollers conforming to SKF Explorer performance class.
SKF tapered roller bearing benchmark test results conclude highly competitive performance on service life, frictional moment, noise and vibration levels and speed capabilities.
As in the past, all SKF Explorer roller bearings have been uprated with an increase of 15 % in dynamic load rating. This is obviously also valid for the catalogue assortment of SKF Explorer tapered roller bearings.
