100 SERIES - Coil Spring Technology

Polymer Concepts seals are designed to provide the optimum spring load and seal geometry required to maintain maximum sealing performance. The primary function of the spring is to provide loading to the polymer jacket to maintain sealing in low pressure applications. In addition, loading can be designed to accomodate critical low friction requirements in both reciprocating and slow rotary applications or provide high loading required for cryogenic sealing. Springs are designed to uniformly distribute loads around the sealing contact surface area. Hardware misalignment and side loading should be kept to a minimum. Side loading impacts a higher stress concentration to portions of the seal jacket, thereby causing excessive wear and limiting seal performance.Under extreme run-out or misalignment conditions, bearings are recommended as part of a sealing system solution. Polymer Concepts seals are available with a variety of spring energizers, each having distinct characteristics to meet specific performance requirements. Springs are fabricated from corrosion resistant metals such as 300 Series and 17-7PH stainless steel, Hastelloy® and cobalt nickel alloys. Elastomer o'rings can also be used as energizers as well as free flowing silicones.

Coil spring samples

Polymer Concepts 100 Series spring is made from flat ribbon metal strip stock that is formed into a helical shape. The standard materials are 17-7 ph stainless steel and 304 stainless steel. Nickel cobalt alloy materials are also offered as an option. The finished spring produces a very high load versus deflection curve. The charts below specify the loads, per inch of circumference, for our standard cross section seals. Should the application require less or greater forces for the application, Polymer Concepts can fabricate alternate spring geometries.

Please consult with the factory for your specific size.
