Topic tags/keywords: question

I am very unfamiliar with ID and OD sizes of bearings and standard pipe (black pipe, ridged conduet, etc). What I need to do for a project is have the slandered pipe say around 1” slide inside the bearing with very small tolerance. That is capleble Of repeatable daily use and of course done as cheaply as possible.

Any help is very much appriceated.
Thanks
Dave

Cheapest would be get some UHMW polyethylene. It is self lubricating and makes nice bearings. Works with regular woodworking tools. Peach Tree sells it among other places.

If you are going to be moving faster than that, pick up real bearings. I get them from Surplus Center pretty cheaply.

I like the UHMW polyethylene idea.

I’m building an adjustable height table. There will be four bearings that pipes will slide in to give stability which is where the close tolerance comes in. I don’t want it to be able to rack. As for speed slow at best so it’s not a concern. I thought pipe because its cheap.

Have your say...
