This, from one:

"Didn't spend a lot of time, but I poked around the Timken site, then went to CR Industries (Chicago Rawhide - now part of SKF). I thought of CR because they were a major customer [when I worked at Allied Spring]. We made millions of garter springs that supply the inward tension for their highly engineered elastomeric shaft seals. As their name implies, they used to make seals out of leather. I was at their facility nearly 25 years ago, and I believe at that time it had been about 40 years since they made a seal out of leather. (my guess)

Anyway, nothing at all on either site about leather.

Could it be that leather historically was favored over other early material choices? These guys are now making seals by the budzillions for all kinds of industries - rail, heavy truck, off-road construction, auto, etc. No leather in sight."
