The QUBE 8-ball bearing is patterned after the Fafnir bearing of the late 70s, using our 3D technology we have re-created this bearing for today's market using modern day technology. This bearing contains 8 balls instead of the traditional 7 which has many advantages. The additional ball allows the load to be spread out evenly over the entire bearing instead of just one or two points. The additional ball also gives the bearing greater lateral load capabilities while turning, an important aspect of quad skating that many overlook. Lateral load is the force created while turning; it's the momentum that wants to push you off the track. Using an 8-ball bearing will help distribute the load evenly over the entire bearing, in essence making a stronger bearing laterally. Combined with a deeper groove this gives you the ability to skate into turns harder with no worry of bearing blow out. For over 3 0 years this type of bearing has been the skaters choice for speed, if maximizing your cornering speed is what you're after then the QUBE 8-ball bearing is the right bearing for you.
