Features

Ultra Mini High performance, Bearing upgrade system, the revolutionary new ultralight skate bearing system.Only NiNjAs are made in Japan at the worlds most advancedbearing manufacturing facility using state of the art materials The entirefacility is an automated clean room for superior finishing and construction. NiNjA Bearing engineers have customized the NiNjA Bearing line to excel forInline speed skating as well as skateboarding demands including unmatched speedunder skate-load, superior side-load speed/strength, and superiorweight-bearing impact shock-load capabilities. NiNjA Bearings are fully SkateTested and Performance Proven. NiNjAs also surpass both ABEC and the morestringent JIS ratings, which is very good. Not bad. NiNjAs high carbon chromebearing steel raceways are purified, refined and finished like no other. NiNjAballs are super-hardened AKS balls, micro-finished to perfection w/ theimplementation of ultra finite ball matching automation for exactness toeliminate wobble, minimize friction and maximize speed.NiNjAs were the first to utilize (and havealways had) cutting edge labyrinth technology with the most effective labyrinthcut and shield configuration for maximum protection of inner bearing parts fromoutside elements while providing unmatched speed. NiNjAs shields also assistw/ a cooler spin and far less heat build-up compared to rubber-coated shields.less heat means less friction and less eventual internal structuraldeformation. NiNjA bearings are easy to service without removing theirsemi-permanentcome in pack of 16 bearings only.
