Chesterton’s Large Diameter Rotary Seal Series Improves the Sealing of Heavy Duty Rotating Equipment
High-Performance Materials Resist Wear

​FOR IMMEDIATE RELEASE

GROVELAND, MA –October 2, 2017

A.W. Chesterton Company announces the official launch of its comprehensive Large Diameter Rotary Seal Series, an extension of Chesterton’s existing rotary seal portfolio. 

This seal series was specifically developed to improve seal performance in heavy duty, industrial rotating equipment. The seal design, materials, and technology provide superior protection against the ingress of solid particles, dust, and fluids. As a result, bearing houses an​d gearboxes are protected even in the most hostile industrial environments. 

The Large Diameter Rotary Seal Series offers high performance, retrofit replacements of most popular industrial rotary sealing solutions and systems that are used in heavy duty applications:

 

  • Chesterton 50K: Rotary face seals (excluders) as secondary seal components for the protection of bearing seals and bearing housing 
  • Chesterton 51K: Rotary seals with a fabric-reinforced back on OD for bearing and gearbox protection 
  • Chesterton 52K:​ Rotary seals with a metallic ring insert (stiffener ring) for bearing and gearbox protection
  • Chesterton 53K: Rotary seals with special spring system (combination of helical garter and finger spring) for high speed and large run-out applications
