Seal Design and Structure
PTFE Hydraulic Piston Rod Seal GSF Glyd Ring/Slide Ring/Step Seal Made in China.BSF Seal Bronze PTFE Compact Piston Rod Seal Glyd Ring SPGO Seal.The GSF profiles are double acting composite seals composed of a filled PTFE friction ring and pre-tightened rubber O-ring.Glyd Ring provides low friction with no stick-slip,minimal break out force and high wear resistance.Teflon seals with excellent low friction and high speed performance,are chemically resistant to almost all media and show excellent performance at high linear speeds and in long stroke applications.
Why Ideal for Space-Constrained Cylinders
Our proprietary seal designs meet users'requirements for low friction,compact form and simple installation.The design can make the product suitable for high pressure conditions up to 40Obar in a double-acting cylinder.The low friction resistance of PTFE makes it suitable for high efficiency systems.Compact design saves groove space.
High resistance against extrusion.
Low friction,high efficiency.
Stick-slip free starting,no sticking.
High abrasion resistance,high operational reliability.
