All Ball Bearings are NOT created equal! Over ten years ago we tested a number of different bearing manufacturers, tolerances, and types of lubrication in order to find an optimal balance of performance, life, reliability, and price for our Ball Bearings. We've done the testing so you don't have to! The resulting bearings are OUTSTANDING, and over 250,000 bearings have been sold to satisfied customers all over the world! Advantage Bearings have been run by some of the fastest racers in the world and have won multiple National Championships. All Advantage products are backed by a Satisfaction Guarantee. We guarantee you'll be happy with your purchase, or we will make it right! Precision Steel Rubber Sealed Ball Bearings The bearing's races, cages, and balls are made from Precision Chrome Steel, and come packed with a high quality grease. The Rubber Seals protect well against exposure to dust, dirt, and moisture, which can destroy bearings. These bearings offer maximum protection at the cost of a bit of resistance (which is largely reduced after the bearings are broken in).
