Are delrin bearings a problem in this application?

I have the famous Craftsman drill press from the infamous sale. In my small shop I need to have wheels on a lot of my equipment. I found these bearings on E-bay but I worry that the Delrin bearings will be a problem over the long run. I know that they are hard but is there a potential issue her over roller bearing wheel sets?

I think it would be fine. alot of casters that size don't have a bearing at all, they just have an axle through the rubber wheel.

I prefer ball bearings, but don't see any reason these won't work for you. Rated at 250# so they won't have any trouble with the weight of the DP.

I scanned through the store and it seems Delrin are the only bearings they use.

Definately buy them, then let me know how they work out!

I need to do the same thing.

Delrin is some really nice material. I use it often as skid bearing surfaces. I also used it to turn some lock nuts for the ball screws on one of my cnc machines. It is a step up in hardness from UHMW and every bit as slick.
It would likely do very well as bearings where you have a very dirty or very wet environment.

Thanks folks. I'll spring for them. Jeff, I'm doing this just for you... riiiiiight!!! LOL!!

Does anyone know where to buy just the wheel portion? I need several 3" wheels of the type used on many of the mobile bases that are out there. But I only see them available as part of a caster, not sold as wheels only.

Delrin is hard and machines well, holds its tolerances relatively well, won't creep or cold flow under load. I don't think its as slick or has a slick, almost oily feeling like UHMW. But its probably good for wheel bushings where you won't be rolling it around continuously all day, every day.
