SAE J1947 (OCT2002)

O.D. Coatings for Radial Lip-Type Shaft Seals

PUBLISH DATE 2002
PAGES 4
SAE J1947 (OCT2002)

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 µm Ra, 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.
  • e. The sealer shall not show any evidence of peeling, blistering, softening, or dissolution when tested in media to be sealed.
