STE807-025-019-003P is a piston seal that works as single acting and can be used in piston applications. The material used on this piston seal is made of PU.
The dimensions has an inner diameter of 19 mm, an outer diameter of 25 mm and a height of 3.25 mm.
About the sealing profile STE807
STE807 Pneumatic piston seals are used in pneumatic cylinders with low friction force due to their special profiled dynamic sealing lip. They are especially designed to be used in short stroke pneumatic cylinders. Standard production of STE807 Pneumatic piston seals is from PU and NBR materials. STE807 PU piston seals can be used safely in pneumatic cylinders although air in the system is not conditioned.
About the material PU
PU is moulded with injection techniques. It has excellent mechanical properties such as high tensile strength, wear resistance, tear strength, and extrusion resistance. It offers a good resistance to air, ozone, mineral oils, grease and aliphatic hydrocarbons. Working Temperature Range: -30°C to 100°C.
