The STB GmbH bearing seals use the power of magnets to create a sealing effect by means of a sliding surface. High precision in manufacturing and assembly allows a balance between low friction power and virtually no leakage in low pressure operation. The perfect alternative to labyrinth seal and drive seals.

Supported by magnets, a continuous pressure is placed on the surface of the seal, creating a contact that reduces the leakage to virtually non-existent. By using magnets and high precision in the manufacturing process, the life of the seal is extended, and the maintenance is widely reduced. Ultimately saving you time and money.

We know that one size does not fit all. Which is why we created 4 different versions of the STB Magforce for you.

Our Products

The Magforce

has an O-ring on the stator and can be easily inserted into the housing.
