Sector 9 Black Ball Ceramic Speed Bearings are built to last you longer than your average steel bearings. The wear better in most situations. Instead of developing groves in the bearing and the race, the ceramics actually repair themselves against the race. You should try these bearings because they are affordable and will last you 3 to 4 times longer than your existing longboard skateboard bearings. Heck, you can clean them too or just keep ordering them from us. If you want to purchase a quality bearing but can afford ceramics, you should try the Platinum bearings by Sector 9.
Sector 9's Description
Rubber coated shield is removable for easy cleaning. Ceramic bearing balls weigh up to 40% less than steel bearing balls, depending on size. This reduces centrifugal loading and skidding, so hybrid ceramic bearings can operate 20% to 40% faster than conventional bearings. This means that the outer race groove exerts less force inward against the ball as the bearing spins. This reduction in force reduces the friction and rolling resistance. The lighter ball allows the bearing to spin faster, and uses less energy to maintain its speed.
