Dave I am reluctant to say pre load as it could imply excessive pressure I may have misled by end float I mean remove all end float so that they are not to tight . in this case too tight is bad to loos not so you can increase the tension if required. but get em tight and the damage may be done I have just done my lathe AC bearings £ 280 each pair and my mill £ 120 for the Taper roller Stuart sorry for the misunderstanding |

How did you ensure even removal of material all over the seating area and prevent the shaft going out of line axially i.e. moving the center line to one side? --- End quote --- Hmm.not sure what you mean here..... Could you rephrase? |

John, what i meant was how did you make sure the shaft did not end up oval, although I realize this would only be a micron or two. My concern is that it may push the center line of the spindle out. Am i just nit picking? |
| John Rudd:
Ahhh...I see.. Ermmmm . Mounted the spindle between centres on my big lathe and just polished the journals sufficient to make the bearing race a tight push fit.... :dremel: |
| Jonfb64:
Just spent 3 hours in the workshop polishing the journal and have achieved what I think is the correct tight press fit. The bearing moved nicely along the shaft when the locking nut was tightened. :D thanks all for the help :mmr: special thanks to John :clap: |
