8Pcs 1/2 Inch Mini Caster Wheels Low Profile, Self Adhesive Single Direction Tiny Wheels, Little Rubber Rolling Wheels with Steel Top Plate for Sm...

The media could not be loaded. I think these are a pretty good option for creating a linear rolling system. They don't have bearings or bushings so I don't foresee them lasting a super long time under heavy loads, but for smaller, lightweight stuff they shouldn't give you any issues. They operate quietly in most cases, although they can squeak when the load is very light. My set came with 21 screws each 1" long, so there are plenty of extras, and a screwdriver. The screwdriver isn't anything to write home about, but the tip geometry is good and it's not so small that you can't hold onto it.

I just received these mini casters and they are perfect for what I am planning to use them for. I have multiple electronic cutting machines and I have seen people glue these to the bottom of their machines. I didnt want to do that so I decided to put 4 of these on a board and put my cutting machine on the board. In my test run, they rolled nice and smooth with no marks or scratches. So excited to have these little casters!

These are nice TINY casters. They work well on some shelving where I set up trays to slide out to make accessing items in the back easier. I put a small drop of light oil on the "axles" and they roll smoothly. Just make sure they'll be big enough for our application.

Not sure exactly where I am going to use these yet. I may use them on the bottom of some small drawers in a woodworking cabinet in the garage. This is a nice little set that comes with screws and even a screwdriver. Great for a lot of different applications where you need a tiny wheel. The wheels are not plastic but kind of rubbery. They roll well but obviously just press fit so will not last long if you put a lot of weight on them.

These little wheels are perfect for various things. They work great for my small appliances that need to go to and fro the appliance garage on my kitchen counter. I also have used them on some rollout storage bins I made for under my bed and they work great. They are also perfect if you don't want to add a lot of height like other wheels would add. Note they don't pivot so you will only get forward and backward movement with these. If you are looking for super small low profile wheels for forward movement I would definitely recommend these.
