    • Very useful
Size: R6-2RS(3/8x7/8x9/32)
These are great, they are ball bearings in an outer metal ring with an inner metal ring, and a black plastic cover on the sides. I had one of the plastic covers warp, although I have no idea why, so then I took it apart and looked at the bearings, which are lubricated as stated. I didn't get it near heat and was disappointed that the plastic warped. Otherwise, I would have given it 5 stars. It worked really well. Be careful of using glue with it, the plastic is thin and would definitely warp, and you wouldn't want to get any blue in the bearings. Do not use in a higher heat environment or the plastic will melt. If you need to attach the bearing, try something like a metal staple. I put a threaded 3/8" rod inside and they fit well together, not too tight or loose. I used it to make a dog treadmill. Works very well for that purpose. You get 10 of these in a nice clear plastic tube, so you may have extra to experiment with. Attaching it to anything is probably the most difficult part of using it. I drilled a hole in wood and then hammered it in. If your hole isn't exact then use extra wood shavings as a shim. Best of luck! Enjoy! ... show more

    • Finally, a 1'4" I.D. bearing that is truly 1/4"!
Size: R4-ZZ (10pcs)
I've purchased several bearings in the past that claimed to have a 1/4" inner diameter that didn't (6mm is NOT 1/4" people). This one really does have a 1/4" I.D.! They fit tightly on to ground 1/4" I.D. steel rods, just like they should. Bravo!

    • Work well in/out of water
Size: R6-2RS(3/8x7/8x9/32)
Use these on a trolling motor shaft and have thus kept the water out. Only issue is these measure 0.373 which is a tiny bit smaller than 3/8 so be prepared for that
