I've done a lot of the conversions. The bearings are a lot thicker than the ball bearings, and accomodations have to be made for that. More importantly, is...
So whatīs the big secret? One needs a washer that is of equal thickness and wider than the tapered bearing so the machine canīt throw chips into the bearing....
I bought mine on Epay Mfr: RB Tech Model: 6206-2RS Dim Spec: 66x66x20 Removal was easy (ofcourse). Installation was tougher. I used a brass block larger than...
Thank you very much for posting this link. That's a really great primer on making gears on the mini-mill -- something I have been thinking about. Maybe now I...
I acquired a set of "factory auhorized" service tools made by Sieg for the particular purpose of removing and installing the X2 spindles nd bearings. Regards, ...
... Yes that would be the helix angle, and I received some very nice emails offering trig to figure the angle as well. However, to my tired old brain, fancy...
I am thinking about doing a change to taper bearings on my Amadeal XJ12-300 mill with a MT3 spindle in the next week or so as well. I am planning to use a...
Does anyone know of a book or video that covers advanced work holding techniques? For instance if I want to cut around a rectangle, I can't do it with one...
The MT3 spindle install with the tapered roller bearings is a simple install. The R8 system is much more complicated, since the lower bearing is thicker in...
The following site has some good pictures of "basic" work holding techniques. I think you just have to be very analytical and creative when it comes to work...
Hi, I'm not aware of any books on the subject myself. Perhaps because work holding in such a varied topic. Every situation is different and it would be ...
Model Engineers Workshop has an ongoing series of articles by Harold Hall on making and using a variety of clamping devices. You will have to purchase a...
Hi, Just to report complete success so far in changing the main spindle bearings for taper ones. Received the bearings at 10am and completed the change by 3pm....
Thanks for the links and hints. It's much appreciated! I have seen mill tables that are covered with a plate with holes drilled in it in a regular pattern....
I don't understand why everyone wants to change to tapered roller bearings when axial ball bearings will do the same thing and take the same loads and you...
An axial ball bearing uses side-by-side races. An axial load is transmitted directly through the bearing, while a radial load is poorly-supported, tends to...
And, "Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the...
They are available only overseas in the Far East. I was on a trip out to Singapore three years, ago, and brought back two sets. I have one that I use and one...
well, i got my new lower bearing yesterday, about two weeks since i had originally started this post (taper roller bearing install? is this hard to do?) and...
I have seen a lot of pictures with the object being milled clamped only from the sides. On the other hand, a draw bar is necessary to avoid getting the mill...
