Axial seals, including the AS-10 and AS-11 models, consist of two parts: a metal ring with a protective layer and a vulcanized elastomeric sealing insert. These seals are designed to provide effective protection and sealing in a variety of applications. The metal ring acts as a clamp, support, and protective barrier for the elastomer seal, while also functioning as a pendulum disc. The elastomer seal, on the other hand, is stretched onto the metal ring and held in place by the axial edge. In the case of the AS-11 model, the metal ring on the outer jacket extends towards the shaft, creating an additional labyrinth seal when combined with the revolving groove on the axial tread.
The elastomeric sealing element of axial seals is typically made of NBR (nitrile butadiene rubber) or FKM (fluoroelastomer). These materials are known for their excellent sealing properties and resistance to various operating conditions.
The metal ring of axial seals is deep-drawn and comes with a protective layer of steel. It is available in different options, including galvanized and stainless steel variants, providing durability and corrosion resistance.
Axial seals are commonly used in combination with oil seals as protective seals. Their primary function is to prevent the ingress of dirt, dust, grease, and splash water. As a result, they find applications in a wide range of sectors and industries, including mechanical engineering, electric motors, drive technology, pumps, agricultural machinery, and even washing machines. These seals play a crucial role in ensuring the reliability and longevity of equipment and machinery by keeping harmful contaminants at bay.
To ensure optimal performance, axial seals must be properly mounted on the shaft with the correct distance between the metal tread and the elastomeric sealing element. This allows for a defined axial preload, creating the necessary pressing force when the sealing lip rubs against the metal tread during rotation. The total axial pressing force is determined by factors such as the preload, sealing lip geometry, and the elastic and tension properties of the elastomer. The centrifugal effect provided by the metal ring further supports the sealing function, protecting the seal against dust, dirt, and splash water.
In conclusion, axial seals offer reliable protection and sealing in various applications. Their robust construction, use of high-quality materials, and effective design ensure their performance in demanding operating conditions. Whether it's preventing contaminants in mechanical systems or safeguarding sensitive components in electric motors, axial seals are an essential component for maintaining equipment integrity and longevity. Choose axial seals for your sealing needs and experience their proven reliability and functionality.
