Nylon, comprising several grades of polyamides, is a general-purpose material in wide use; it is tough and resistant and has good pressure ratings. Polyacrylates are not recommended for dry running applications. This dimension refers to the housing bore diameter or the seal outside diameter. In opposed seal elements, the two seal lips point in opposite directions. They are comprised of a rotor (rotating) and stator (stationary) member. These seals are used where it is desirable to have a back-up seal incorporated into one seal case or shell. User may specify either, both, or neither of the "At Least" and "No More Than" values. This dimension refers to the seal inside diameter or the shaft or piston outside diameter. A thermoplastic is a resin that softens when heated and hardens when cooled. SHAFT BORE WIDTH PART NO. An elastomer is a polymer that has the elastic properties of natural rubber. SHAFT BORE WIDTH PART NO. It has excellent chemical and fatigue resistance, and thermal stability. Also referred to as having an inner case, which implies that it also has an outer case.
