You can have the existing hubs recovered with polyurethane which will give you superior traction to the OEM rubber tires on your F38. ? I use Griffith Polymers who acquired Axiom in 2021 for feed rollers on my F38 and for the feed rollers on my Dual 51 J/P, ?You send them your existing hubs/tires, they recover them and send them back. ?Call them at 503-620-2439. ? I have also used Fletcher Machine Industries in the past, but it’s been a while since I used them. ?They are at 800-438-1054?

You can buy new hubs/tires from Western Roller but they do not recover existing hubs. ?The dimensions on the replacement hubs/tires they supply are slightly narrower, and they are offset from the edge of the feeder housing making it more difficult to get the tires right up against the fence plates. ?Western Roller info is here: ?https://westernroller.com/
