Best Choice for shock absorber oil seal factory .
What is an oil seal?
Oil seal is the customary name for general seals, which is simply the seal of lubricating oil.
Oil seals are generally divided into single type and assembly type. The assembly type is that the skeleton and the lip material can be freelycombination, generally used for special oil seals
What is best brand for oil seal in shock absorber industrial :
NO.1 , NOK
Obviously NOK is the famous brand for oil seal in shock absorber industrial . We have many customers who assemble shock absorber ,according to our experience , because the important role and the price is not so big in the shock absorber parts , many customers who want to make high quality shocks are use NOK brand . Max Auto is the sales agent of NOK brand , NOK have factory in China.
NO.2 RFX
However due to NOK company is so big , their price is high and they are not willing develop new mold if quantity small , it is not easy to buy the correct one from NOK company .
The second brand is China top brand RFX , the price is a little lower than NOK , but quality is top level also . We can also help you buy if you are deal with shock absorber assembly .
No.3 China local brand
Because NOK and RFX both big company , if your quantity is small , it is not easy to buy from them , especially if you are doing repair shock absorber , they are impossible to to develop new mold for you , so the best Choice is China local brand .
We are selling these local brands in a large quantity to all over the world .
Max Auto Parts Ltd made the oil seal is use the high quality material , we have currently developed more than thousands of molds , that is easy for your choose the correct one to fit for your shock absorber .
What is the material of the oil seal?
Commonly used materials for oil seals are: nitrile rubber, fluorine rubber, silicone rubber, acrylate rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material of the oil seal, the compatibility of the material to the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft at high speed must be considered. Generally, when the oil seal is working, the temperature of its lip is 20~50℃ higher than the temperature of the working medium, so it should be paid attention to when selecting the oil seal material. For details, please refer to: Rubber Types and Properties. The working range of the oil seal is related to the material used for the oil seal: -40~120℃ when the material is nitrile rubber (NBR), -30~180℃ for acrylic rubber (ACM), and -25~300℃ for fluorine rubber (FPM).
Type of oil seal
| type | code name |
leading feature |
use |
| Ordinary single lip shape |
B |
Generally used for high and low speed rotating shafts and reciprocating motion to seal mineral oil and water and other media.。 |
Ordinary oil seal, used in the case of less dust and impurities, when the medium pressure is less than 0.05MPa, the maximum linear speed is 15m/s, and the reciprocating speed is less than 0.1m/s. |
| Ordinary double lip shape |
FB |
In addition to the use characteristics of the S-type oil seal described above, it can also be dust-proof. |
Ordinary oil seal, with dust lip to prevent dust, medium pressure resistance <0.05 In the case of MPa, the linear speed is less than or equal to 15m/s。 |
| No spring type |
FB |
In addition to the use characteristics of the S-type oil seal described above, it can also be dust-proof |
Ordinary oil seal, with dust lip to prevent dust, medium pressure resistance <0.05 In the case of MPa, the linear speed is less than or equal to 15m/s. |
| The outer skeleton is a single lip shape |
BV |
Single lip type inner skeleton rubber oil seal without spring |
Generally suitable for low speed conditions, the sealing medium is lubricating ester. Linear speed≤6m/s. |
| External skeleton double lip shape |
FW |
Double lip exposed skeleton rubber oil seal with auxiliary lip, thin waist, good followability, high rigidity and good coaxiality. |
Ordinary oil seal, with dust lip to prevent dust, medium pressure resistance <0.05 In the case of MPa. Speed ≤ 15m/s. |
| Prefabricated single lip shape |
Z |
The outer skeleton oil seal is assembled from the inner and outer skeleton and has the characteristics of high installation accuracy, fast heat dissipation and heavy load. |
Suitable for heavy-duty working conditions under high temperature and high speed, medium pressure ≤ 0.05MPa, maximum linear speed ≤ 15m/s。 |
| Prefabricated double lip shape |
FZ |
The assembled outer skeleton oil seal with auxiliary lip has the characteristics of dustproof, high installation accuracy, fast heat dissipation and heavy load. |
It is suitable for high temperature, high speed, and heavy load conditions under the condition of dust, medium pressure ≤ 0.05MPa, and maximum linear speed ≤ 15m/s. |
| One-way return type |
Right SR, left DL |
The lip air is measured with oblique ribs with an angle. Using the principle of fluid mechanics, it produces a one-way pumping effect and has a backflow effect. |
It is related to the rotation direction of the shaft. Due to the backflow effect, the radial force is smaller than that of the ordinary oil seal, which reduces the wear and heat generation, and improves the service life. |
| Pressure resistant type |
NY |
Short lip, short and thick waist, with pressure resistance, working pressure ≤ 3MPa。 |
It is suitable for occasions where the medium pressure is less than or equal to 3MPa, and is suitable for the shaft end oil seal of the high-pressure pump. Generally, the PV value is less than or equal to 8. Rotation axis speed≤15m/s |
Folding function use
Engine: Crankshaft–Crankshaft front and rear oil seal valve–valve oil seal (engine repair kit o-ring) (distributor oil seal, water pump oil seal, balance shaft oil seal, oil pump oil seal…); Camshaft–Camshaft oil seal ; Transmission: Transmission–transmission front and rear oil seals, shift lever oil seal (transmission repair kit o-ring) (transfer case–transfer case front and rear oil seals); Rear axle: half shaft–rear half shaft oil seal difference Gearbox — (front) rear angle vector oil seal, rear wheel oil seal, front wheel oil seal, direction oil seal (steering machine repair kit o-ring), steering booster oil seal (front axle oil seal).
All parts that have liquid lubricating oil in the running body box and are connected to the outside need oil seals. Some are rubber, some are metal, most are steel rubber, such as crankshaft rear oil seal, gearbox front and rear oil seals, left and right half shaft oil seals, main reducer front oil seals, air compressor crankshaft oil seals, etc.
Max Auto Parts Ltd made the oil seal is use the high quality material , we have currently developed more than thousands of molds , that is easy for your choose the correct one to fit for your shock absorber .
We can also buy other brand like NOK , NAK or RFX for other customers .
