I recommend ordering several extras because this poor sellers inventory situation is a mess. I had to return several of these before I finally got the right size/correct part number.

4.0 out of 5 stars good but odd sized grease fittings
Reviewed in the United States on September 15, 2024
I used these on the idler shaft on my old Delta 12" lathe. I had to cut off the two tabs to mount the bearings in the lathe's bearing holders, but that was quick and easy. I'll have to look for a grease gun tip that fits the half-sized fittings, though.

5.0 out of 5 stars Really TIRED of PLASTIC....
Reviewed in the United States on June 19, 2024
Flimsy light weight bushings...SO upgraded my tractors steering, you know like wheel bearings, thrust bearings etc. etc.. However never got around to the big one, the steering collum...that's a main problem with pretty much all garden tractors. Critical parts are CHEAP, CHEAP, CHEAP made out of plastic. And there not cheap in cost, So I order this ball bearing to replace the cheesy plastic bushing one. I got TWO of them at a price of one crap plastic one...WHAT a diff it makes. like power steering time. If you want better steering. Like, man go for these they're a great value and super-fast delivery. Thanks Amazon and the seller!!!

5.0 out of 5 stars Needs to have the mounting holes size listed.
Reviewed in the United States on May 13, 2024
I purchased these as better alternative to the junky end plate / bearing assemblies for my garage door whan I had to replace the torsion springs. There are plenty of replacement bearings listed for these end plates, but some end plates are impossible to remove the old bearing without a press and the correct intallation bushing; your only choice being to purchase new end plates with the same crappy bearings installed. The old plate assemblies were fastened with 5/16 bolts. The mounting I.D. on the block is a little over 5/8 but I was able to find nylon bushings to solve that issue. The self aligning is a huge plus as are the set screws to secure the bearing to the cross shaft.
My garage door is happy and quieter now.

1.0 out of 5 stars Center to center mounting hole dimensions WRONG!
Reviewed in the United States on October 23, 2024
I machined my base plate for these bearings based upon the listed dimension. It was WRONG! Caused me to rework. Unacceptable. Hopefully the bearings perform. PS.. I’m a retired mechanical engineer.

4.0 out of 5 stars Feel good
Reviewed in the United States on January 30, 2024
Big holes to secure the base, the bearing in the base feels nice and tight, not loose, also feels greased already as it turns slow. It has one grease screw, i got the 3/4 inch inside diameter the measure it spot on,(i use my measuring tape)all metal except for the grease seals they seem pretty secured in their place. Overall feels like it will do its job.
