2. Application scope

 

A double combination seal consisting of a PTFE shaped sliding ring and a rectangular ring as a preloading element. Especially suitable for use as a piston rod sealing system for heavy-duty hydraulic cylinders with large piston rod diameters and extremely harsh operating conditions.

 

 

 

3. Applicable occasions:

 

For example, it is used in injection molding machines, metallurgical machinery, marine hydraulic equipment, hydraulic presses, engineering machinery, cranes, hydraulic control systems, etc.

 

 

 

4. Reference standards:

 

Merkel OMS-S product standard.

 

 

 

5. Features and Advantages

 

 

 

1. High wear resistance

 

2. Strong resistance to gap extrusion

 

3. High voltage withstand characteristics

 

4. Low friction, does not cause "hydraulic crawling".

 

5. Adopting anti twist design, stable working performance.

 

6. The elasticity of rubber has high contact pressure and good compression resistance.
