Hi all. Looking for some advice on machining dimensions for a felt seal. What I want to do is keep dust out of a fairly large bearing with a 290mm (11.4in) diameter shaft going through it which rotates at 150 rpm. I don't know much about felt seals other than having replaced felt wicks and wipers on a lathe. I know it seems to swell when it's soaked in oil. If you know all about felt seals please share. The material I'm looking to work with is an SAE F-1 grade wool felt with a 6.4mm (0.25in) square cross section. Thank you.
