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

 

GSJ shaft seal is generally used in hydraulic reciprocating Motor system. Suitable for sealing applications under high, medium, low pressure, heavy load, and high-frequency conditions, it is very excellent. Suitable for various stroke and wide range fluids and high temperature situations, suitable for larger piston rod clearances.

 

 

 

Applicable environment:

 

For example, it is used in bulldozers, excavators, forging machines, ceramic brick presses, steel rolling machines, servo valves, and machine tools.

 

Reference standards:

 

Comply with GB/T 15242.1-94 and GB/T 15242.3-94 standards. You can refer to Trelleborg's RS1 series, Merkel's OMS-MR, and Parker's OD series standards.
