Rotary Seals
AST’s rotary seals are made for peak performance and enduring durability through thoughtful design and expert manufacturing.
AST’s Rotary Seal
Rotary shaft seals are designed to retain lubricants within mechanical systems while preventing the ingress of contaminants from the external environment. Commonly used in rotating and oscillating applications, these seals play a vital role in protecting bearings, shafts, and other critical components.
AST rotary seals are engineered to provide excellent wear resistance, reduced friction, and extended service life, helping improve the overall performance and reliability of your equipment.
We offer a comprehensive range of rotary sealing solutions, including high-performance radial shaft seals manufactured in-house to ensure consistent quality and full control over the production process.
In addition to fluid retention, our rotary and linear sealing solutions can be designed for a variety of specialist functions, depending on the application requirements, operating conditions, and media involved.
