Click To Enlarge

The 47SRB Solid Bearing Axles by Derby Evolution measure .091 into the body and then step down to .047 where the bearing rides. This allows for a precise fit between the bearing inner race and the axle. The length of the center .091 section measures 1.75 inch, and the .047 bearing axle on each end is .5 of a inch.  These bearing axles are the perfect size for whatever class you are allowed to run them in. This allows you to get the ultimate speed from your Pinewood Derby Car.

The fastest bearing setups are using bearings with an inner race that measures .0469, the 47SRB is designed to be just oversize allowing the user to polish the axle to the exact diameter and giving the precise press fit. Using an axle that is to small allows the inner race to turn on the axle, slowing your car down. The best axles will fit the inner race and not allow it to spin on the axle.

  • Manufactured from the highest quality stainless steel

  • Full radiused ends, making them much easier to use
