I have an Adcock & Shipley horizontal mill which I have just acquired, and which I have stripped down for total rebuild/paint etc. Long story short, I knew that it had a “noise” issue, as the seller volunteered this when I rang him. I haven’t heard the machine running, but bought it unseen. To get it into my workshop, I had to remover the saddle, and upon doing so, decided to do a complete strip down etc.
I have located what I’m sure is the “noise”, as when I took the belts off, and tried the pulley’s by hand, the middle stack (the one which is slide adjustable at the rear of machine) seemed almost seized. On further inspection, the two bearings on the shaft had dried grease that resembled varnish. After cleaning the bearings still seem like they may have seen better days. I’m not sure how to fully check if they are okay, or actually need replacing, but maybe I’ll air on the side of caution.
The bearings are open race, and the shaft assembly is such that it has a grease nipple.
I am unsure whether or not to stick with open race, or, to opt for sealed bearings. The top speed of the shaft is 2500rpm (shaft size is 40mm, outer dia is 80mm). The machine is maybe 60 years of age, and I am unsure whether or not bearings have advanced sufficiently in that time as to warrant a change, or, should I stick with original spec?
I’m also now, going through ALL of the bearings on the machine, as I want to bring the Mill back to it’s former glory, and give it a new lease of life.
