Polyurethane Hydraulic Cylinder Piston Seal PTFE + NBR Spgw Excavator Parts Oil Seal

 

 

**The performance of the combined oil seal SPGW is very good, and it is suitable for a variety of complex working conditions**.

1. **High sealing performance**: SPGW piston oil seals are designed with a multi-layer structure, including guide rings, O-rings and sealing seats, which can effectively prevent liquid or gas leakage and maintain the stability and reliability of the system [^2^].

2. **Excellent Abrasion Resistance**: SPGW piston oil seals are made of highly wear-resistant materials, which have excellent wear resistance, can maintain good sealing effect under long-term high-speed movement, and prolong service life [^2^].
   
3. **Good pressure resistance**: SPGW piston oil seal can withstand work in high pressure environment, has high pressure resistance, and is suitable for various high-pressure hydraulic systems [^2^].

4. **Wide temperature range**: The special material of SPGW piston oil seal can adapt to different working temperature ranges, from low temperature to high temperature, to ensure the stability of sealing performance [^2^].

5. **Dust Resistance**: SPGW Combination Oil Seal can effectively prevent the intrusion of a variety of media and protect the equipment from contamination and wear [^1^].

6. **Extrusion and abrasion resistance**: It can also be used safely in dirty media, with good leakage control, extrusion resistance and wear resistance, and is mainly used in cylinder piston sealing of heavy-duty or construction machinery [^3^].

To sum up, SPGW combined oil seals are widely used in many fields such as construction machinery, aerospace, petrochemical industry and other fields with their excellent performance characteristics, and have become an important guarantee to improve the sealing performance of equipment and ensure the stable operation of equipment.

 

The parameters of SPGW combination oil seals include size, pressure, speed, temperature, material and application industry. Here's a closer look at these parameters:

1. **Size**: The standard size of SPGW combination oil seal is 80*65*11, but according to different application needs, there are other sizes such as 180*157*15.5 [^4^].
2. **Pressure**: The maximum pressure that SPGW combination oil seals can withstand is 50MPa[^1^].
3. **Speed**: The maximum allowable operating speed of the SPGW combination oil seal is 1.5m/s [^1^].
4. **Temperature**: SPGW combination oil seals are capable of operating in a temperature range of -40°C to +160°C [^1^].
5. **Material**: SPGW combination oil seals are made of a variety of materials, including PTFE (polytetrafluoroethylene), NBR (nitrile rubber), FKM (fluoroelastomer) and POM (polyoxymethylene), etc. [^1^][^2^][^3^].
6. **Application Industry**: SPGW combination oil seals are widely used in construction machinery, aerospace, petroleum, chemical industry, metallurgy, electric power and other industries, especially in the fields of excavators, standard cylinders, mobile hydraulic equipment and hydraulic presses, etc.

In general, SPGW combination oil seals have been widely used in various industrial fields with their excellent performance parameters, which not only improves the reliability and production efficiency of equipment, but also reduces maintenance costs.
