Oil seal
Application
Automobile oil seals are usually attached to the end face of the rotating part of a unit. The oil seals help to prevent oil leakage or the entry of small foreign objects into the engine. Therefore, the shape and roughness of the oil seal surface are strictly managed so that the attaching part is securely sealed. Because oil seals are generally made of rubber, using contact-type measurement equipment may affect their surface profile and lead to inaccurate data.
