GSI anti grid ring - GSI shaft grid ring - NO piston rod seal - RG rod grid ring - XAB shaft seal

1. Standard materials:

 

Sealing body (sealing ring): filled with PTFE F-PTFE and polyurethane sealing ring

 

Elastomer O-ring: Nitrile rubber NBR or fluororubber (FKM, FPM)

 

 

2. Application scope

 

The shaft is generally operated in a hydraulic reciprocating motion environment using a grid to circle. Correct use can achieve excellent piston rod sealing in high, medium, low pressure, heavy load, and high frequency operating conditions. The GSI type shaft uses grid rings, which are particularly suitable for long stroke situations and can be used in a wide range of fluid and high-temperature situations, and can be suitable for large piston rod clearances. For example, it is widely used in equipment such as excavators, bulldozers, forging machines, ceramic brick presses, steel rolling machines, servo valves, and other machine tools.

 

 

 

3. Reference standards:

 

When designing and selecting GSI type shafts with grid rings, reference can be made to Parker's ON series and Trelleborg's RG4 series standards.

 

 

 

4. Features and Advantages

 

1. The groove is simple and can be used for integral pistons.

 

2. Low friction and no crawling phenomenon.

 

3. The static sealing performance is very good.

 

4. Due to the large extrusion gap, it can also be safely used in media with dirt.

 

5. Due to the use of a large number of materials, it has strong adaptability to working conditions.

 

6. Large extrusion gaps can be allowed, depending on the application situation, thus reducing processing costs.

 

7. Suitable for the latest environmentally safe Hydraulic fluid (bio oil).
