PGN (2 Pack) 6203-2RS Bearing - Lubricated Chrome Steel Sealed Ball Bearing - 17x40x12mm Bearings with Rubber Seal & High RPM Support

glad I made the choice into buying these bearings. I have a super quiet motor now. pressure is at full throttle.

Installed these into my two idler pulleys on my Toro ZTR mower. One bearing is buttery smooth and is all a bearing should be. The other however, seems to have a slight tight spot when manually rotating it and it feels as though metal is turning on metal. I removed the grease seals (barely had grease inside it), and I added some Valvoline w/moly high temp bearing grease. This seemed to improve the feel but it still seems to have a more slight metal on metal feel. Plan to use them until failure - after all, they were less than $4 each folks!!! I really liked the pliability and tight fit of the grease seals and the fact that they snap back into place when reinstalling...

They come with some kind of clear grease on one side that might be enough for some applications, but considering these are going in a Honda HS520 snowblower exposed to sodium chloride infused ice and snow a little extra grease should help them last longer. I popped the seals with a small eyeglass screwdriver and repacked with Mobil 1 waterproof wheel bearing grease. This is the third set of bearings Ive replaced on this snowblower. These were about 1/6th the cost of OEM Honda bearings and once packed with grease I expect these will be last I buy.

Needed two bearings for a unit that was down, the manufacture wanted $27.00 for one bearing. We replaced both for less than the cost of two. Great value.

Works great (so far) as replacement bearings for a unicycle.

Cheap bearing that didnt measure to the dimensions as advertised. If you need precision this wont do or maybe it will depending on the manufacturers quality control. I ended up paying 5 times more with McMaster-Carr but getting the precision for my application was worth it.

Turn my booster pump from a screaming banshee to a purring kitten

It was used to couple a electric motor to a compressor

Its round and rolls

I rebuilt my pool pump motor in March 2022, its now August 22, 2022 and the bearings are already failing. They started howling last week. Dont waste your money on this garbage. Spend a few dollars more for Tonkin bearings.
