Description:Because noting rolls like a ball, use micro-ball bearings! The key to building any record setting vehicle is to reduce friction as much as possible, the most common friction points are between the axles and the frame. Micro Ball Bearings are designed to replace all energy wasting bushing systems with a more efficient ball-bearing that will reduce the total friction by as much as 50-100%; this means your vehicle will travel up to 50-100% further and faster than the rest. Micro-ball bearing also decrease the normal wear that occurs between moving parts and helps eliminate heat build-up so your vehicle can use more of its starting energy for increased performance. Micro bearings take a little more work to set-up and are intended only for those individuals who want to set a new school record. Micro-bearings can be used with all rubber band and mousetrap racers that uses a 3/16-inch axle. This is a 10-pack set of bearings, order as many sets as you need for your next large group activity.
- reduce friction
- improves performance
- decrease wear
How it works:Micro-ball bearings are mounted into the frame of the vehicle and hold the axle from touching the frame. Instead of the axle rubbing on the frame as with a bushing system, micro-ball bearings hold the axle and allow it to spin on a surface of tinny balls that reduce the surface friction to near zero. Micro-bearings have an outer diameter of 3/8-inch and an inner diameter of 3/16-inch. In some cases, axles need to be sanded to fit the bearing since the bearings are manufactured to a much higher tolerance than most hobby tubing. A complete instructions guide is included with this set.
Ball bearings require more work than bushing systems but the rewards are well worth the work. Ball bearings can be used with almost all Doc Fizzix kits and when purchased with any one of our pre-drilled kits we will resize the holes on request to accommodate the bearings.
