The 18.2mm Aluminium Axle and hub spacer snugly rests between the base of the Axle against the hanger and the bearing housing inside Trampa Hypa or Superstar Hubs. They are precision engineered to ensure accurate fit; 1 spacer fits all! Fits all Trampa Truck Axles and Trampa Hypa Hubs.
This Bearing Support Spacer fits between the Bearings, alongside the O-Ring when fitting Bearings into a TRAMPA hub when mounting the wheel onto 9.525 & 12mm Axles.
Over time, during the usage of your board, bearings & spacers are put under a lot of force. Ultimately this force has to go somewhere. The Bearings use a Steel ring in their assembly where as the Bearing Support Spacers are made from Aluminum - & when forced against each other the aluminum will lose every time! This is what happens to your spacers between the bearings, & over time the spacers shrink, resulting in an annoying rattle. That's when you fit these spacers!
