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 and 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:

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

Chesterton Rotary Seal Benefits

Applications: Designed for heavy industry: Steel and Aluminum Mills, Hydropower, Mining and Ore Processes, Cement, Pulp & Paper
