About the TC profile
The TC arrangement — rubber-covered case, garter-spring main lip, external dust lip — is the industry’s go-to solution wherever a shaft spins in an oil-filled housing.
NBR nitrile rubber at a glance
Material-wise this is NBR nitrile: a balanced compound for mineral oil, diesel-range fuels and greases at moderate temperatures — ideal for rotating equipment. Two cautions: no exposure to glycol-based brake fluid, and keep stock seals out of sunlight.
Don’t worry if your micrometer shows the shaft a few tenths under size — the garter-sprung lip is designed to seal against exactly that condition.
