I have a 1/4 inch shaft that’s in two bearings at each end which are in turn in bearing blocks. I want to stop the shaft from moving left or right. I have a 1/4" ID x 1/2" OD shaft collar but it’s too big - it rubs on the outer edge of the bearing, and I can’t seem to source a smaller one.
Other option seems to be to cut a grove in a split ring - but I don’t have access to a lathe and it’s only a couple of shafts - too small a job to pay someone to do it.
Any other options or anyone have a small metal lathe I could ply with beer and / or cake?
I may have spoken too soon. Any and all 1/4" ID washers I can find are at least 1/2" OD and the bearing is only 1/2" so back to the same problem - the collars I have are 1/4 ID 1/2 OD hence the rubbing. Ideally I want 1/4 ID and 3/8 OD but this is very very thin washer.
If you don’t plan on taking it apart I used loctite 680 to fix all the drivetrain gears to shafts on our motion control rig.
It’s really strong stuff, a drop is enough. Heating it breaks the bond if you want to unglue it. You could put some on bearings i suppose. We bought pillow blocks off simplybearings.com which have grub screws already in them, you could also switch to those.
Or make a groove with a file and use surclips ? should be small enough to only touch the moving part of the bearing.
I can do that between the collar and bearing, to stop the rub, cheers.
