Chesterton Introduces Innovative Labyrinth Seal to Protect Bearings, Gearboxes, and Motors in Oil Splash Applications​
Non-Contact Design; Thwarts Outside Contaminants

​​​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.

  • High-performance, non-contact design eliminates fretting caused by lip seals
  • Keeps lubrication in and positively seals out bearing contamination
  • Unitized design and durable material provides easy mounting
  • Available in various configurations to meet plant-wide equipment needs
  • Same-day shipment availability, minimizing downtime and associated costs
  • Standard sizes available for popular equipment, customs available upon request
  • IP56 third party certified; designed to provide ingress protection from dust and water
