At high shear forces, hard fabric guide rings must be provided for safety. These can be fabricated in almost all sizes. Elastomer Sealing Component (Part C) Material: modified NBR approx. 80° ShoreA This sturdy sealing element is made from high grade anti wear NBR and excels due to low compression strain as well as high tensile strength. Optimal molecular structure is achieved through the special manufacturing process for the sealing element. The geometrical part is made of the sealing faces reduces the so called "stickslip effect" of the seal against the cylinder rod surface. The assembly is easy (from d=60 mm and up) Support Ring (Part B) Material: Polyester Elastomer This support ring serves to absorb forces against the NBR sealing ring. It help to per- form uniform pressure distribution on the support ring and works against extrusion of the NBR sealing ring. Back-up Ring (Part A) Material: glass filled POM This anti extrusion ringmade of glass filled Polyacetal prevents extrusion of the sea- ling element in the event that pressure surges occur. 94 AG Rod Seal
