Four times longer service life - at the very lea

Research based on the analysis of 1,000 bearings shows that 99.6 % of CeramicSpeed bearings last at least 4 times longer than standard bearings. In 50 % of the cases the service life of the bearing was between 8 and 20 times longer than the bearings they replaced - even under the influence of sever particle contamination.
