FB type fkm nbr oil seal 30*45*8, output shaft rubber seals, 30*45*8 Oil Seal
Oil Seal Introduction
Oil seals – often called grease, fluid or dirt seals – close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. Preventing harmful containments from entering machinery is another critical function of an oil seal. Vital components of practically every type of machine and vehicle in operation, oil seals protect all types of precision-constructed, close-fitting ball, sleeve and roller bearings. In a typical application, the oil seal is installed adjacent to a bearing, sealing in or sealing out, as necessary, the various liquids, gases or solids encountered by the particular mechanism.

Common types of oil seals
| Type | Shaft Movement | Features | Main Applications |
|---|---|---|---|
| FB | Rotate | Double lips, inner metalcased. | For sealing medium and tiny dust operating conditions. |
| S or B | Rotate | Single lip, inner metalcased. | For oneside sealing medium and no dust operating conditions( Max. Pressure 0.03Mpa) |
| OS | Rotate | Single lip,outer metalcased.Good stiffness, good heat distribution and good coaxiality. | For sealing medium and no dust operating conditions(Pressure Max.0.03Mpa). |
| zs | Rotate | Single lip, assembled seal withmetalcase. Good stiffness, good heat distribution and good coaxiality. | Used in Sealing oil and water, no dust. Higher pressure resistance than general oil seal. |
| OD | Rotate | Double lips, Outer metalcased. | For sealing medium and tiny dust operating conditions. |
| ZD | Rotate | Double lips, assembled seal. Good stiffness, good heat distribution and good concentricity of inner and outer diameters. | Used in Sealing oil and water, no dust. Higher pressure resistance than general oil seal. |
| WPS | Rotate | Single lip, inner Outer undulatory surface for easy installation and better sealing. | Same as Type S and B. Widely used in lightalloy and split housing. |
