Qube Ceramic Skate Bearings Qube Ceramic skate bearings use the finest ceramic ball technology with eight balls instead of seven. Skaters prefer ceramic bearings as they last longer and perform better than steel because of their tolerance to heat and other harsh conditions. The eight ball bearings helps better distribute the load. These bearings are suitable for most current roller skates, blades and inlines. Sold as a set of 16.Size: 7mm or 8mmFit: Most current roller skates and roller derby skates have 8mm axles, some older styles or Roll-Line plates come with 7mm. Most inline skates use 8mm bearings. A simple rule of thumb is: 7mm are rare, 8mm is the most common. If you're unsure, contact us or put a note on your order to ask us to check. Don't forget! One skate wheel requires 2 bearings (one on either side of the wheel core). 4 wheels require 8 bearings, 8 wheels require 16 bearings.Online Only Brand: Qube Bearings
