STA311-140-155-006S is a rod seal that works as single acting and can be used in rod applications. The material used on this rod seal is made of PTFE+GLASS.
The dimensions has an inner diameter of 140 mm, an outer diameter of 155.1 mm and a height of 6.3 mm.
About the sealing profile STA311
STA311 rotary rod seals are composed of a special compound of bronze-filled PTFE which is then combined with an o-ring that is used as an energizing ring. They are designed to provide imperviousness under high pressure in rotary applications. They are suitable for high sliding speeds due to the low friction force which is among one of the essential properties of PTFE material. Moreover, they can be used for different type of oils except mineral oils by changing o-ring material.
About the material PTFE+GLASS
Fibreglass filler provides chemical resistance in a wide range of working temperatures. It is especially resistant to powerful alkaline solutions and hydrofluoric acids.
