Rotary Seals

Keeping Lubricants in Place
Rotary seals and shaft seals are used in components with oscillating or rotating parts to keep lubrication fluids in while preventing ingress of mud and water. Trelleborg seals help improve components life and long term performance.

Yimai Sealing Solutions offers a wide range of specialized Rotary Shaft Seals, including our best-in-class proprietary radial lip seal and high quality radial oil seals.
Yimai ‘s portfolio of rotary seals includes the commonly known radial oil seal, rotary shaft seals, radial and axial lip seals, double-acting O-Ring energized Polytetrafluoroethylene (PTFE) rotary seals for shaft and bore, rubber V-Rings, mechanical face seals / heavy duty seals and many more.

Extending component life
Our specialized Rotary and Shaft Seals perform exceptionally well in many different rotary situations. They demonstrate superior low-friction properties and provide excellent resistance to wear.

Rotary and Shaft Seals for many different application
With special seals, like the Radial Oil Seal and Radial shaft seals without a tension ring, the range of applications goes beyond fluid sealing. This special form of Rotary Shaft Seals can also serve as a scraper in situations with helical movement. Learn more about the various applications for Rotary Shaft Seals and Shaft Seals in our Film on Rotary and Shaft Seals.

  • Compact installation length. Minimal starting friction ensures consistent movement, even at low speeds, without crawling. Reduces friction losses effectively. Offers excellent resistance to crushing forces. Withstands high temperatures with reliability.  
  • Compact installation design. Minimal starting friction ensures smooth and steady movement, even at low speeds, without any crawling effect. Effectively reduces frictional losses. Exceptional resistance to crushing forces. Highly resistant to elevated temperatures.  
  • The V-ring VA is an innovative all-rubber seal designed specifically for rotational applications. It provides excellent protection against dirt, dust, water, and other contaminants while effectively retaining grease. Thanks to its unique design and functionality, the V-ring VA is suitable for a wide variety of bearing types and can also serve as a secondary seal to enhance the performance and protection of the primary seal.  
  • The V-ring VS is a specialized all-rubber seal designed for rotating applications. It effectively prevents the intrusion of dirt, dust, water, or a combination of these elements, while securely retaining grease. Due to its unique design and high performance, the V-ring VS is compatible with a wide range of bearing types and can also function as a secondary seal to safeguard the primary seal.
