Rotary Shaft Seals

Shaft Seal Types: A, AH, AOH, AO, AD, AOD, AE, AF, AOF, AN

Rotary shaft seals, also known as radial shaft seals or simmer rings, are lip seals designed for rotating shafts. They are widely used in industrial machinery for maintaining tightness between stationary and moving components.

Type A Shaft Seals

Type A seals are suitable for medium-speed rotating shafts. The recommended pressure limit for this design is 0.02 MPa, depending on the elastomer – usually NBR (nitrile rubber) or FKM (Viton). They provide efficient sealing for standard applications in rotating machinery.

Type AH and AOH Shaft Seals

Designed for low-speed shaft rotations, AH and AOH seals offer enhanced tightness, making them ideal for systems requiring sealing under pressures up to 0.5 MPa. These seals are perfect where fluid retention and leak prevention are essential.

Type AO Shaft Seals

AO seals operate effectively at pressures up to 0.02 MPa. They feature an additional dust lip and allow for lubricant application (such as grease) between the sealing lips. This added feature protects against dust and extends the lifespan of rotating equipment. AO seals are available in metric and imperial sizes, using either NBR or FKM materials.

Special Shaft Seals: AD, AOD, AE, AN

Types AD, AOD, AE, and AN are custom-engineered shaft seals used in specific industrial applications. These seals are evaluated and priced individually due to their specialised requirements and bespoke designs for high-performance systems.

Reinforced Shaft Seals: AF and AOF

AF and AOF shaft seals come with reinforced walls, clearly visible in cross-section diagrams. These reinforcements enable the shaft to rotate at higher speeds and provide increased mechanical stability. Ideal for high-demand industrial operations with intense and continuous use.
