Hi Jon, Thank you for your reply. For your information, my lathe chuck is a 100mm (4"). As far as I know the bearings are of the tapered type but I didn't verify, just referring to the drawing and the

Ryan, I agree with you and I'd like to add some comments. Concerning the use of tapered bearings, my lathe came with them and I didn't touch them until I decided to get rid off a bad surface aspect. A

No, tapered bearings aren't sealed, see my other post, you'll see that I'm wondering how to ensure their maintenance. The gear side might be accessible for oiling when the nuts, the pulley and the

You're correct but the lathe was delivered with such bearings.

Roy, I already have tapered bearings but my problem is that they are mounted tight and I can't manage to reduce the clearance between them.

Hi John. Yep, my lathe is a two speed one and I have the LMS metal gears in it. To me the gears are pretty quiet. If I grab the chuck and rock it back and forth there's some gear clunk naturally but

Thanks Ryan for your experience and results report Is your lathe a 2-Speed and are you running metal 2-speed gears as well? How is the gear meshing noise? TKS, John

My tapered rollers have been in for 10 years. I haven't touched them in 3 1/2 years since I installed my els. I pulled the rear when I had the nuts off to install some parts for that and in the prior

I am on the fence about ACR vs TR, Did you get rubber seals on your bearings? Do you oil them regularly? Maybe 1 drop before each use? Does oil leak out the bottom of the bearing or middle of the

I believe the OP has tried to install tapered roller bearings and can not get the preload just right.? I could be wrong tho, even very wrong is possible.....

I like the part *The only benefit to higher precision bearings in the spindle is reducing wallet weight!* This ball bearing I purchased 1,000 at a time in class 3 / motor grade. It very good ball

What this whole thread is overlooking is the fact that the OEM bearings are deep groove ball bearings; the cheapest option! An upgrade to angular contact bearings gives more thrust resistance to the

You have to consider that the Craftsmen "rotary triple" gizmo for three tools also provides a little flat workbench space on each side of the tool.? That is probably useful.? It is true that you

The lathe & mill are roughly the same weight (45kg & 55kg?) and the centre of gravity would be roughly at the pivot point (biased towards the mill as it’s heavier & taller) so flipping wouldn’t

I’ve thought of doing a slide-out rack for my laser engravers (got 3 of them). The “blue boxes’ as they’re known. They’re not too heavy (20-25kg?) but I’d still need some reasonably hefty

That Craftsman table is a bit bigger than it needs to as it has three tools, you could do two stands with two tools each for not that much more floor space. I was planning on making some for the

If look engineering press fit ball bearing some very light press for heat build-up so ball bearing does seize up. Other times they not ver good at machining for ball bearing.? A 1? ball bearing need

Hello PR, My experience with these bearings is that they can be hand tight, up to press tight.? On an automobile the bearing is slip fit on the spindle and press tight on the hub, so use your

Jon, Interesting vids. They tend to confirm that a press is needed for dismounting and remounting. However, no figures are provided concerning the applied forces. Referring to the ISO286 adjustment
