J1947_200010: O.D. Coatings for Radial Lip-Type Shaft Seals

Features

Issuing Committee: Seal Forum Committee

Scope

Content

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 R_a, 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.
