Please choose your specific Boosted Board model from the drop down: either V1, V2 or Mini as the larger bearing sizes are different for each. The V1 Boosted Board uses 10 bearings, all others use 8 bearings total.
Complete upgraded precision ceramic bearing kit for your Boosted Board engineered by us to roll smoother, last longer, and increase your range due to this lower rolling resistance. These are the best bearings for your Boosted Board - GUARANTEED - or your money back! ABEC 7, 100% synthetic ACER Racing SIN oil lubricant, superlite bearings.
With ACER Racing's National and World Champion reputation in the high performance ball bearing industry we set out to engineer the best Boosted Board Ceramic bearings at any price.
First we started with our tried and tested diamond polished 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 our special synthetic and American ACER Racing SIN oil lubrication in the smaller bearings and our ACERGoo American synthetic grease in the larger 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 nylon inner ball bearing cage, which is the recommended material for durability and strength with superior heat resistance at high RPMs. This insures that your 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 seal is embossed with our trademark "ACER RACING CERAMIC" logo to insure that you are receiving the original ACER SK8 ceramic skate ball bearings.
