- 8mm, Silicon Nitride ceramic balls with stainless steel races and nylon retainer.
Cheezeball Swiss Bearings are what put Cheezeballs on the map. They are some of the best bearings that you will ever skate on, period. We started out with Silicon Nitride ceramic balls, one of the hardest ceramic compounds in the world. This is the same material that is used in aerospace applications and is capable of 35,000RPM at over 2,000 degrees! We paired them with rustproof deep groove 440 stainless steel races and noncorrosive nylon cages, all of which are built to ABEC 7 tolerances. We chose 440 stainless because it is virtually rustproof and slightly softer than chrome steel, which allows the insanely hard Silicon Nitride ceramic balls to “dress out” small scratches and imperfections in the bearing race, resulting in THE SMOOTHEST, LONGEST LASTING ROLL EVER at a price that’s nearly half of any other high end ceramic bearing available. With occasional cleaning and lube these bearings will last longer than any other you’ve tried! As with all Cheezeball bearings, our Swisses are ABEC-7 rated and are cleaned, dried, oiled, test spun and double sealed BY HAND to weed out any defects.
