An odd size seal

10 July 2024 | David

I could not find this particular sized shaft seal (47 x 56 x 7) anywhere else, I needed an increased internal diameter to accomodate a stub axle repair where the seal track was severely pitted, a speed sleeve wasn't available in the size I required either so I made my own from F51 duplex stainless.
