  • Cheers all, they appear to make 2 types for the PF30A, an outboard ABEC3 and an angular type, I can't understand the difference or which one I'd need, I've sent an email asking for clarification unless anyone knows the answer......

  • Angular contact bearings are better at dealing with axial loads than a normal deep groove ball bearing so should have better longevity.

    They however generally have more friction and can be noisier.
