40% Bronze PTFE Hydraulic Piston Seals for GSF
GSF
Quantity:
1. Application and properties：
Suitable for double-acting piston seals, especially for fast response cylinders in control oil cylinders, servo oil cylinders, machine tools, and construction machinery.
It has a low friction coefficient, wear resistance, and a long service life. It can work with or without lubrication and can be used for non-oil lubrication cylinder seals.
The adaptability to working media and working temperature range can be changed by replacing the material of the O-ring. Can be used in special working conditions such as extremely high speed, extremely low speed, micro-stroke, etc.
Suitable for integrated piston, and the installation groove is small.
Complies with the standards of GB/T 15242.1-94 and GB/T 15242.3-94.
Good extrusion resistance and larger installation clearances than general seals.
Different cross-section products can be selected according to the actual working pressure value. Generally, the larger the working pressure, the larger the cross-section product should be selected.
2. Standard material：
Sealing ring: filled PTFE
Ring: NBR / FKM
