Rotor PF30 Threaded Cup Steel Bearing

Online exclusive
{{ vm.state.webThumbOverlay.code }}


Crafted from 7000 series aluminum alloy, the UBB4630 uses a threaded sleeve to lock both cups in place – without having all the locking effort rely on the press fit shell, thus providing a uniform spin and avoiding undesired noises. The flush fitting in the press fit region prevents bearing overload and also improves bearing alignment for a longer bearing life.
