This enquiry is from a friend of mine:
what do they call the implement that you'd use to protect a bearing
whilst it is being pressed into a housing ? I'm thinking along the
lines similar to a drift that you'd use to knock a bearing in, but I'd
be using a hydraulic press to push the bearing in and so I want
something fit for the job that'll go in between the press and the
outer race of the bearing.
I'd use a suitably sized socket.
