BEARINGS ABEC 7 RS CHROME Nils Extreme bearings are the most precise bearings in the ABEC scale. They are made of highest quality chrome steel. ABEC 7 RS CHROME Nils Extreme bearings have the lowest rolling resistance which results in the highest speed capabilities according to American standard Annular Bearing Engineering Committee (ABEC). Another important parameter of those ball bearings is their eccentricity – roundness on the track in the inner race, that is only 0,0025 mm. Specially designed housing unit is made of metal and rubber and it protects bearings against unwanted contamination. RS means a special rubber cotter pin, easy to remove and making it easier to clean the bearings. ABEC 7 RS CHROME Nils Extreme bearings are intended for inline skates, skateboards and scooters.
