5.0 out of 5 stars That's a big bearing!
Reviewed in the United States on June 25, 2024
I know I checked the measurements before ordering, but these are a lot bigger than I imagined. I needed all of these to build up some trucks for a CNC. The fact that these are so large was a concern initially, but I managed to tweak my design and make these work. Their rolling action is very smooth and quiet. The fact that they are double sealed will keep any dust and debris from clogging the bearings. I think the larger size is a benefit for what I am making because it feels very stable.
Highly recommended!

5.0 out of 5 stars Great pre-lubricated bearings!
Reviewed in the United States on June 26, 2024
I like these come pre-lubricated, so I could just install them. I feel like the rubber seals will keep out dirt, and give these a longer life. I replaced some inferior ball bearings that wore out quickly with these, and these work a lot better.

4.0 out of 5 stars The bearings feel like the grease is a bit sparce
Reviewed in the United States on June 23, 2024
When I spin the bearings they feel like there's not a lot of grease inside them. Not really rough or noisy but just dry sounding. I only needed a couple so I might pull off one of the rubber seals and see just how much is in it. I know that things like angle grinders sold by the national tool store that sells mostly Chinese tools often need to be pulled apart and packed with more grease. That could be the case with these.

So far the bearings are working just fine. I had a 3/4hp electric motor that was in a flood. Both bearings were destroyed so I replaced them. Not wanting to spend much money not knowing if the motor could be salvaged I got these to test. Once installed they seem to spin just fine. I have plenty of spares so I can try to add grease to the next set if the first two don't last.

Other than the grease they seem to be made very accurately. The pressed onto the motor shaft just as tight as the old ones came off. The fit into the end caps nice and snuggly but not requiring too much force that would have damaged them. I was able to get the motor running so I will be able to find out how long the bearings will last.

I only used these for a small project so no heavy loads have been applied. However, they operate very well with no resistance and to turning.

They came in a nice plastic container with a matching lid so keeping unused ones stored is easy and they stay clean.

5.0 out of 5 stars Top-quality product
Reviewed in the United States on June 16, 2024
These bearings are exceptionally well-made. All were greased properly and are double-sealed. No catches in the rotation whatsoever. All three dimensions are true. Top-quality, well done. I'd buy again.

5.0 out of 5 stars Great for track idlers.
Reviewed in the United States on June 12, 2024
I got them to repair faulty cheap Chinese excavator and skid steer’s track idlers. One needs 20 of per machine, so getting a 10-pack is great. They are both-side covered. One wish the 52x25 seals were available in such packs too.

These bearings are absolutely massive. I bought them for a special project and they perform very well. Very smooth rotation.
