never hurts to try. my sons 2 skate boards we dismantled this fall testing out the fastest wheels for his soapbox. the skate wheels spun 5-6 revolutions when spun hard. the bearings in them are ones much like the abu bearings. i sprayed them with a soaking of wd-40. they then spun for almost a minaute. be amazed what a good oil will do for moving parts.
