These are replacement bearings for most yo-yos carried by YoYoExpert.  They are stainless steel 8 ball flat bearings.  They are clean spinning so lube is recommended if you want to keep them responsive or prolong the overall life span.

Available in three sizes:

Size C (.250 x .500 x .187) - Fits most YoYoJam, YoYoFactory, SPYY, CLYW and many other manufacturers

Size A (5x10x4 mm) - Fits Duncan, and YoYoFactory Small Bearing Yo-Yos

Size D (5x11x5 mm) - Fits HSpin, some older SPYY models

All bearings come pre-cleaned and are stainless steel for long spin and unresponsive play.
