Dragon Precision Self Centering Spacers are manufactured to provide a precision fit with extremely low tolerances in-between your skateboard or inline roller skate bearings. This allows you to crank your axle all the way down, which in turn reduces slop and increases the longevity, durability and performance of your bearings by great amounts. Width - 0.4" (10.35 mm) Axle Size - 8mm Precision Machined for Extremely Tight Tolerances - Between +/- 0.001 mm
Construction - Machined Aluminum for protection from rust. Durability - Equal to the durability of stamped steel with a more precise fitment. Perfect Fitment for Dragon Endure and Race Bearings - Designed and tested to work extremely well with our Dragon Bearing lineup.
