NOTE: These bearings are ABEC7 size 627 2RS bearings for 7mm axles NOT 608 bearings for 8mm axles. The inner diameter is 7mm which some skates use please check your particular skates to see if this is what you need. If not, we also sell 608 ceramic skate bearings which are for standard 8mm axles with an inner diameter of 8mm. For skaters looking to upgrade from their Fafnir 37K 8 ball bearings these are the best choice.
With our National and World Champion reputation in the high performance ball bearing industry we set out to engineer the best ceramic skate bearing at any price. First we started with our tried and tested Ceramic Nitride Pro Series silicon nitride balls (Si3N4). The same super hard balls that gave us the reputation as "the hardest balls in the industry." These balls are matched for consistent concentricity per set. They are polished using diamonds for a super smooth and shiny finish. Their durability is unmatched by any other ball or material in the industry. With a melting temperature of 2552 degrees F and the best modulus of elasticity in the world, these are the best balls period. We use a special synthetic lubrication in our ceramic skate bearings which has an extremely wide service temperature range of from -50 to +120 degrees Celsius with an incredible speed factor of 1 million. We integrate our HSR inner ball bearing cage for durability and strength with superior heat resistance at high RPMs. This insures that your ceramic skate bearings will spin faster, longer. We seal our ACER SK8 ceramic skate bearings with two no contact grey seals which will resist the elements while allowing simple removal for easy cleaning when necessary. Each bearing is laser etched with our trademark "CERAMIC NITRIDE PRO SERIES" logo to insure that you are receiving the original ACER SK8 ceramic skate ball bearings. These are the best ceramic skate bearings at any price. Whether used in your skateboard, inline skates, roller skates or anywhere a size 627 size 7x22x7mm ball bearing is used, rest assured you will be running the finest ball bearings in the industry.
