Basic Info

Model No.: Stephen-SRS-

Product Description

Design description:

The seal is generally composed of a rubber O-ring and a PTFE ring. The O-ring is a force application element, which provides sufficient sealing force and compensates the PTFE ring. It is applicable to the sealing of hydraulic cylinder piston rod. The stem seal is a single acting seal, which is divided into stem seal for piston and stem seal for piston rod. Styroseal has the advantages of low friction, no creeping, small starting force, high pressure resistance, simple groove structure, etc.


SRS multi-pieces are used in series to provide

optimum sealing performance for high-speed applications; SRS is also a commonly used cushion


seal that counteracts high frequency pres sure
throughout the seal system and protects the primaryseal.

SRS uses Jiu Long high performance PTFE packing material P4 for superior wear and extrusion resistance

and a wide temperature range and media.

This designalso works with the O-ring elastomer to compensate

for machining tolerances and displacements.



Performance and use

It is composed of a wear-resistant, low friction filled PTFE sliding ring and an O-ring Rubber Seal. O-ring provides preload, which can compensate the wear of sliding ring. It has a bidirectional sealing effect and is suitable for sealing high pressure and low speed rotary holes in hydraulic equipment. Split groove shall be adopted for the specification with hole diameter less than medium 40.

characteristic


1. The sealing efficiency is high when two media need to be separated (e.g. liquid/liquid or liquid/gas)
2. With low friction and high elasticity, it has dual security
3. Good dynamic and static sealing performance
4. Large extrusion gap is allowed, depending on the application, so the processing cost can be reduced
5. With pressure maintaining function, small leakage in oil cylinder
6. The groove design is simple and the installation space is small. The groove size shall conform to IS07425/1, and it can be interchanged with grid ring, seal, etc
7. Because many kinds of materials can be used, it has strong adaptability to working conditions
8. Good sliding performance, no creeping


Standard materials

Sealing ring: filled with polytetrafluoroethylene (F-PTFE)
O-ring: NBR Nitrile Rubber or FKM
Star ring: NBR or FKM

The inner surface of the cylinder should be honed (GH) or 0.4~3.2umRz (0.1~0.8umRa)
Polished (RLB) but in harshly lubricated strips
More polishing is required under the piece.
