Precision sealing
for Bicycles
Your Battery Must Stay Protected from Rain and Dust
Your e-bike integrates a battery and an electric drive motor that are continuously exposed to water spray, dust, and debris from the road. Poorly engineered sealing solutions can allow moisture to penetrate battery cells or motor windings, compromising durability and long-term performance. Continuous vibration adds a further challenge, placing additional stress on poorly protected connections and interfaces.

Our Sealing Solution Portfolio
O-Rings and Metal-Rubber Bonded Seals
Our O-rings and metal-rubber bonded seals protect battery systems and electric assist motors against moisture and dust ingress through designs that minimize the risk of installation errors. Metal-rubber bonded seals address one of the most vulnerable points in an external enclosure: sealing beneath screw heads and threaded connections.
We offer a broad range of elastomer families and material grades, enabling precise adaptation to the compression loads and performance requirements of each assembly.
Body Sealing Solutions
Our body sealing solutions protect all critical interfaces of the frame and battery housing that are continuously exposed to outdoor conditions. These solutions are engineered to support the electrical insulation and charging system performance requirements specific to e-bikes.
This expertise also extends to thermal event management and serviceability, helping improve both the safety and maintainability of your components throughout their lifecycle.
