XiKe (10 Pack) 6203-2RS Double Sealed Deep Groove Ball Bearings, 17x40x12mm, Pre-Lubricated for High RPM, Chrome Steel P6, ABEC 3

Seem like really good bearings, perfect fit for razor SX500 forks. Replaced the shielded head bearings with these sealed ones and so far they are a lot smoother and seem to operate way better. Being sealed I’m hoping they stay clean and hold up well.

Exactly the perfect price, durability looking for in quality, functionality with ease of installing. Looks like a great seal quality and grease content my husband was looks for in parts.

fit well nice and quiet

These bearings came in a plastic tube with a cap. Each bearing is marked with its number on both seals plus the inner race face is laser marked with the manufacturer's name, bearing number and bearing ID, OD and width. The bearings are smooth to rotate and show attention to detail. I decided to check the OD of a few bearings to see if they comply to ABEC 3 specification. For the 30 mm diameter the OD tolerance should be 0 to -9 micrometers. Different bearings showed different measurements, but for the same bearing the roundness was within 2 micrometers. It may not be good for industrial use, but for me it would be OK.

Perfect fit for gen 2 Can-am Outlander/ Renegade trailing arms. There are 8 total to replace, so a pack of 10 for this price is a great deal. Not crazy about the lack of grease, so I did pull off the seal and repack them.

Bought these after my pool pump started screeching like a banshee. For the price, I figured better get 15, and use the best two out of the set. Turns out they are all of the same quality, that is to say, good quality. Given the wet application, I didn't try to remove the seals to repack the grease like others have, but I did not feel it need them. Honestly though, if the bearings last a season or two and I need to replace them, I'll be fine with it. For the rest of this review, I'm leaving a couple of tips for those that are attempting the same project I did... The motor was a nightmare to pull apart. All four thru bolt snapped, with 24 hour soaked penetrating oil, tried gentle hand torque, and impact. When I finally got it apart, I found that the bolts seized to the housing (end pieces) from from galvanic corrosion. Even twisting them with vise grips (flush to the aluminum) it still snapped. Ended up drilling them out (poorly). I found locally that Tractor Supply Company carries 8-32 12" threaded rods that work just fine. Coated them in anti-seize paste (aluminum stuff). If you do attempt this project and end up buying a new motor, I recommend you pull those thru bolts out, one at a time, and coat them with anti-seize. That was the hardest part of this project. Not replacing the bearings, but dealing with the thru-bolts. 1 week in, the bearings are working just fine. As a matter of fact, they are working so well, I forgot how quiet the motor is supposed to be. Happy customer.

Smooth. Excellent value

Good quality bearings . Works fine no noise and been on for a couple of months with no problem a lot cheaper than OEM bearings from John Deere

Li ho utilizzati in sostituzione dei cuscinetti dei mozzi delle ruote delle mie biciclette che, piuttosto spesso, viaggiano con me cariche di bagaglio. Fanno benissimo il loro lavoro, anche se (il controllo è una mia abitudine farlo con i cuscinetti in generale) i miei esemplari sono arrivati privi di grasso tra le sfere e le piste di scorrimento. Estrarre il sigillo e ingrassarli con un buon grasso per cuscinetti è questione di secondi, ma innervosisce il fatto che la fabbrica li consegni secchi, suppongo per risparmiare sul costo del grasso. Li consiglio perché al tatto e all'uso sono davvero precisi e privi di tolleranze avvertibili, ma occhio all'ingrassaggio.

I'm sure the bearings work good.. but I'll never know , Canada post brought me an empty package.. they clearly damaged the packaging and it fell out or they took it out... Not happy
