| Type | Code No | Feature | Use |
| Common single lip | B | It is generally used for sealing medium such as mineral oil and water with high and low speed rotating shaft and reciprocating motion. | Ordinary oil seal, used in the case of less dust and impurities, resistance to medium pressure < 0.05Mpa occasions, the highest line speed of 15m/s, reciprocating speed <0.1m/s. |
| Normal double lips | FB
| In addition to the use characteristics of the S type oil seal, it can also be dustproof. | Common oil seal, with dustproof lip can be dustproof, resistance to medium pressure <0.05
In the case of MPA, the linear velocity is less than 15m/s. |
| No spring type | BV | Spring-less single lip type inner-wrapped skeleton rubber oil seal. | Generally suitable for low speed working conditions, the sealing medium is lubricating ester. Linear velocity is less than or equal to 6m/s. |
| Outer skeleton unillipped | W | Single lip with spring outer skeleton type rubber oil seal, thin waist, good followability, good rigidity. | Ordinary oil seal, used in the case of less dust and impurities, resistance to medium pressure <0.05MPa occasions. Rotating shaft linear velocity ≤15m/s. |
| Exoskeleton bilabial | FW | The double lip shell type rubber oil seal with a pair of lips, thin waist, good followability, high stiffness and good coaxiality. | Common oil seal, with dustproof lip can be dustproof, resistance to medium pressure <0.05
MPA occasions. The speed of 15 m/s or less. |
7/5000 Assembled single lip | Z | The outer frame oil seal is made by the inner and outer frame assembly and piping, and has the characteristics of high installation accuracy, fast heat dissipation and heavy load. | Applicable to high temperature, high speed conditions under heavy load conditions, medium pressure ≤ 0.05Mpa, the highest line speed ≤15m/s. |
| Assembled double lip | FZ | The assembled outer frame oil seal with auxiliary lip has the characteristics of dustproof, high installation precision, fast heat dissipation and heavy load. | Suitable for high temperature, high speed, heavy load conditions under dust conditions, medium pressure ≤ 0.05Mpa, the highest line speed ≤15m/s. |
| Unidirectional reflux type | Right-handed SR,
Left-handed DL | The oblique bars with an Angle are measured in the air of the lip. Using the principle of fluid mechanics, the one-way pumping action is produced and the backflow effect is obtained. | It is related to the direction of rotation of the shaft. Because of the reflux effect, the radial force is smaller than the ordinary oil seal, which reduces the wear and heat generation and improves the service life. It is suitable for the occasion of medium pressure < 0.05Mpa and the speed is less than or equal to 20m/s. |
| Compression type | NY | Lips short, waist short and thick, with pressure resistance, working pressure ≤ 3Mpa. | Suitable for medium pressure ≤ 3Mpa occasions, suitable for high pressure pump shaft end oil seal, under normal circumstances PV value ≤8. Rotating shaft linear speed ≤15m/s. |
Characteristics of internal rotation labyrinth seal:
1.The inner rotary oil seal is actually a kind of structure type of rotary seal, which is generally composed of moving ring and static ring.
2.It is the use of the structure of the shape of the arrangement, so that the path of oil leakage elongated, as if into the "maze", and leakage of oil, because of the role of rotating centrifugal force, can return halfway and no longer leakage.
3.Due to less friction than the skeleton oil seal, and the higher the rotating speed, the better the sealing effect, it is often used in high-speed rotating occasions.
| NBR | Excellent resistant to oil, Low temperature resistant,widely used in industrial area |
| EPDM | Excellent resistance to weather and ozone, good resistance to heat, low temperature and chemical |
| NR | High elasticity, good chemical strength |
| CR | Generally good resistance to ozone, aging ,and chemical, good mechanical properties over a wide temperature range |
| SBR | Shock resistance,performance well in adhesion and sealing |
| SILICONE | Widest operating temperature range, performance stably in high and low temperature,widely use in food sealing area |
| VT/FKM | Excellent resistance to high temperature and a broad range of chemical, permeability and compression set are excellent |
| HNBR | Thermal stability and oxidation resistance |
| IIR | Low permeability rate and good electrical properties |

FKM Advantage:
Fluorocarbon (FKM/FPM) is a well-known rubber with high performance and a co-polymer composed of highly fluorinated hydrocarbons. It shows excellent resistance to high temperature, fuel oil, hydraulic oil, ozone, media and aging. However, it is unstable to polar solvent, such as MEK, acetone and ethyl acetate. The parts made with FKM generally refer to the fluorocarbon contented with 66% of fluorine, which is also known as ®. FKM is used at temperature between -25°C~300°C for long term operation. The instantaneous temperature can reach 250°C, however, the life time of rubber will be shorten.
The requirements of the oil seal on the assembly shaft:
1. The surface roughness of the shaft is in accordance with the provisions of GB1801. The shaft surface in contact with the oil seal should be ground to a surface roughness Ra0.2 ～ 0.63um and Rmax = 0.8 ~ 2.5um.
2. The diameter tolerance of the shaft shall not exceed h11 according to GB1801.
3. The chamfer width is according to GB13871-92.
4. Surface hardness: The material of the shaft is preferably carbon steel and alloy steel. The recommended hardness is HRC45 or higher. When the medium is dirty and has contaminated impurities from the outside or the linear speed of the shaft is ≥12m / s, the surface hardness of the shaft It should be HRC50 ～ 60, and the depth of quenching layer should be ≥0.3mm.
5. The shaft is chamfered at 30 degrees (maximum). There should be no burrs, sharp corners, and spiral processing marks on the chamfer. The roughness of the chamfered surface Ra ≦ 3.2um. The heat-treated carbonized layer must be polished and removed.
