These bearings are made in house on our Swiss lathe using Natural (white) Acetal Plastic. The Grade 5 Silicon Nitride Ceramic Balls are supplied by BC Precision in Chattanooga, Tennessee. We chose the natural color plastic so you can see any gunk that needs cleaned off and - because it looks awesome! We cut the ball sockets as big and as loose as possible for a free rolling ball, but just tight enough to allow the balls to hold the cage off the scale to ensure no drag. This creates a super fast bearing! Our "Cookies 'n Cream" bearings will fit all existing Roosevelts.
Please Note: Bearing orders may take a few days to ship due to assembly and packaging time. Thank you for your order and for your patience!
