A.W. Chesterton Company has introduced a high-performance Polymer Labyrinth Seal with a non-contact design which virtually eliminates fretting caused by conventional lip seals and helps to reduce maintenance costs associated with premature bearing and gearbox failures.
This innovative seal combines Chesterton's exclusive polymer material with a patent pending design. The unitized, non-contacting 3-piece labyrinth design includes a rotor, a stator and a built-in valve with no wearing parts. While in operation, lubricant is contained within the labyrinth and flows back into the bearing housing while outside contaminants are excluded, by centrifugal force and gravity, and redirected through a relief port back to atmosphere.
Designed to Reduce Contaminants
A unique built-in valve design is activated by shaft rotation to reduce contamination of the bearing housing while in operation. This feature also engages during shutdown periods to create a positive seal during idle time, eliminating ingress of external contaminants.
The material technology is manufactured from an advanced, durable, maintenance-friendly polymer compatible with common bearing and gear oils and offers a cost effective alternative solution to other material options.
The 130-year-old A.W. Chesterton Company operates in over 100 countries around the world and is recognized as a leading international provider of knowledge backed solutions, customized programs, and hands on expert service for Rotary, Stationary, and Fluid Power equipment platforms; supported by a comprehensive line of industrial fluid sealing systems, high performance protective coatings, and specialty industrial lubrication.
