--- Quote from: Ben on June 09, 2017, 04:46:05 PM ---Did this on my CJ18A "taper rollers" did not fit the shaft difference in dimensions damaged the shaft, plus seals are a problem this cost me a new shaft, so went with angular contact bearings Looking back i think the original bearings where just as good --- End quote --- Shame I did not hear of this earlier..... Ben, the spindle on the mini mill/lathe is designed for standard ball races, and as such are an interference fit on the shaft and housing. Taper rollers are designed for a slidibg fit on a shaft with an interference fit in housing. When I change both of my machines to tr bearings, I used wet n dry paper to polish the spindles for a tight sliding fit of the inner races to ensure the bearings would preload on assembly. |

On my Boxford they're not John. Had a hell of a job dismantling the spindle. |

well i did lots of research read your comment's and sought the opinion of good friend's and i decided i'll go with the taper roller option, but at the same time i'm investing in a new 4 inch spindle. |
