Description
The rod sealing set profile GSJ is a typical single acting step seal, and is composed of a PTFE+bronze slide ring and an o-ring.
Characteristics
- Good static and dynamic sealing performance - Good dimensional stability - Easy assembly - High resistance to extrusion - Low friction with no stick-slip - Buffering for strong pressure |  |
Application
The GSJ is generally applied in hydraulic reciprocating system. In high, medium, low pressure and heavy load, the sealing situation under high frequency conditions is very good. Suitable for a wide range of strokes and a wide range of fluids and high temperature applications, for larger piston rod clearances.
Application such as bulldozers, excavators, forging presses, ceramic presses, rolling mills, servo valves and machine tools. It complies with GB/T 15242.1-94 and GB/T 15242.3-94 standards.
