Review on 🔒 PGN 6201 2RS Sealed Ball Bearing: Superior Quality and Performance by Andrew Walton

Used these to replace broken wheel bearings on my Coleman rt200 mini bike. After they were replaced, one of these new ones exploded again about 30 miles later. Maybe that's not because of the bearings as they are used in sand which tends to absorb metal. I replaced the same bearings again, but this time I removed the bearing side cover and stuffed it with Red N Tacky grease. From the factory there is very little fat in it. The boxed kit far outlived the intact factory stores.
