Radiamatic Shaft Seals for a clean world

The requirements are high. Freedom from leakage is not only a "must" for drive shafts in shipping. Cleanliness is also of utmost importance in the paper industry with its high-speed rolls. There are other key factors in addition to the required high functionality: robustness, ease of installation and above all the quick availability of shaft seal rings, for example, in the steel industry. Freudenberg Sealing Technologies has risen to these challenges and provides made-to-order shaft seal rings with the maximum leak tightness and reliability for a wide range of applications.

The newly developed Merkel Radiamatic RPM 41 (Fig. 1) is an example of a shaft seal ring made-to-order by Freudenberg Sealing Technologies. In addition to its FEM-optimized design, a special material was developed for the Radiamatic RPM 41. The seal lip made of pure elastomer requires no spring for pre-tensioning and offers minimal friction along with a maximum sealing effect. A vulcanized-in pre-tensioning element provides a tight, secure fit in the installation space. This prevents potential damage to the installation space. In addition, a special production process makes the seal’s high availability possible: All the current standard profiles with any diameter up to 1,100 mm can be delivered within 24 hours when necessary.
