Fitting its name, the Center Trac Ultimate bearing is our absolute favorite bearing for any unresponsive yoyo that uses a standard C sized bearing.
The Center Trac Ultimate Bearing combines all the best attributes of other bearings into one for unmatched performance. Featuring ten ceramic balls, the Center Trac Ultimate bearing spins longer, plays smoother, requires less maintenance, and has to be replaced considerably less often than typical steel yoyo bearings. The string centering Center Trac bearing shape offers significant performance advantages over typical flat yoyo bearings, especially during long off axis tricks.
For the best possible performance, we recommend that all bearings, including the Center Trac Ultimate Bearing, is lubed regularly with Thin Yoyo Lube.
