In the two pictures below you can see the white delrin bearings that support the main moving parts You will see that the blade is supported with 1 delrin bearing and 1 bronze bush in the centre Most other brands are only supported by 1 bearing on the outside with no centre bearing We have found it takes 3000 hours for the outside blade bearing to wear from 1mm standard thickness to 1.1mm first oversize It can take many years to get up to 3000 engine hours note .1mm = 1 hair thickness
