Sure-Grip Qube 8-Ball 8mm Black (Set of 16) Roller Bearings discountable We do recommend the useThe 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
