I bought 20pcs. to replace the metal bushings on my CR01 Rock Socker. Yeah Racing logo are engraved on each bearing. A lot cheaper than Tamiya own brand 1050 metal bearing, and provide rubber sealing to water and dust which I guess is good for off-road and low speed crawler. Previous review said it does not spin freely, it's true for all rubber sealed bearings because there is friction between sealing and bearing shell.
Anyway, good value for the money I paid. I don't expect there will be the same quality as SKF...haha
