Because what they avoided saying is that because it's a sintered material (i.e. Metal powder fused together) it's impact resistance isn't all that great, and I'm not convinced it will work in this application. Like has already been said, I don't know why you'd use this when correct parts are available. I'm not that familiar with big seven stuff, but I imagine there should be a bronze washer in the recess, with a hard steel washer above. An I bternet search should easily find both of these.
