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.

Fits my older Yard Machine riding mower blade spindles. Installation tip. Plastic PVC coupling worked fine as something to contact only outer part of bearing on side that is installed flash(tapping on it with a hammer). PvC coupling wouldn't go below flush for the other side. Paint roller worked fine for the other side. Installed as lubricated from the factory. Will see how long they last. Easy to install.

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.

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.
