SAE J1947_200210

This SAE Information Report covers thin coatings of resinous based materials that can be placed on the metallic outer diameter of radial lip-type shaft seals to provide sealing when the mating bore finish is too rough to insure a proper seal (typically when finish exceeds 2.54 \gm r\da, or in pressurized applications).

The coatings will have the following characteristics: a.) material shall dry to a tough, flexible, and non-tacky film; b.) thickness typically ranges from 0.005 to 0.076 mm; c.) It shall not crack, flake or powder when scraped; d.) Coating shall adhere to seal case as noted in text; and e.) The sealer shall not show any evidence of peeling, blistering, softening or dissolution when tested in media to be sealed.
