Rotating shafts can be found in general mechanical engineering, the electrical, gas, coal, chemical, food and paper industries, as well as in railways and shipping. James Walker® Co has long held a leading position with its products in this field, based on a consistent policy of research, development, quality control and service. The choice of materials for the production of rotary seals is made individually, taking into account the prevailing operating conditions. A wide range of different materials are available. WalkerSele® is a spring-loaded lip seal of remarkable simplicity, originally developed for use in roll journal bearings in metal rolling mills. WalkerSele® differs from most other spring-loaded lip seals in that it has no metal parts other than a simple tube spring and can be supplied either endless or splitted.
