I would look for an axle that is similar without the bearing spacer. Then, find a piece of tubing that has an inside diameter slightly larger than the out sided diameter of the axle. If your axle is a 14mm, then look for tubing with an inside diameter 15mm. (Link to example below.) I usually use stainless steel, but you can also go with aluminum. Be sure the outside diameter of the tubing must be smaller than the inside diameter of your hub. Then cut the tubing to the exact length of the bearing spacer on the original axle. Link to an example of the tubing. Be sure to measure your axle to look for the correct size. The link below has an inside diameter of 15mm and an outside diameter of 19mm. You would have to check to see if the inside of your hub is bigger than 19mm. https://www.amazon.com/uxcell-Stainless-Seamless-Straight-Capillary/dp/B0FKFNLX2N/ref=sr_1_15
