Inside the TC double-lip design
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.
About the NBR nitrile compound
The seal lip is moulded from NBR, a nitrile rubber prized for resistance to mineral oil, grease and hydraulic fluids — the default elastomer for general machinery. It should not meet brake fluid, and stored spares fare best away from UV light.
It is normal for a shaft to measure a few tenths of a millimetre smaller than nominal; the sealing lip is engineered to take up that difference.
