Hydraulic Auto Parts Trailer Oil Seals , Front Wheel Hub Rubber Oil Seal Motor Car Bearing
Product Description
Oil seals are used to prevent internal lubricant leakage and prevent the external fluid,dirt,dust or any other substances entering moving components in mechanical equipment. An oil seal normally consists of three basic components: the sealing element(rubber part),the metal case, and the spring.
| Material | Temperature Range (℃ ) | Advantages |
| NBR | -40~120 | Excellent resistance to mineral oil and water |
| Silicone | -50~250 | Excellent resistance to heat, cold resistance, weatherability |
| FKM | -20~200 | Excellent resistance to most kinds of oil and solvent |
| EPDM | -50~150 | Excellent resistance to ozone, ageing, weathering |
| PTFE | -50~250 | Excellent resistance to cold, heat, chemicals, low friction coefficient, weatherability |
| PU | -50~150 | Excellent resistance to abrasion and high pressure |

Part Of Oil seal catalog structure
| 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. |
