Bicycle bottom bracket with optimized seals

Challenge

High-quality bicycles for world travelers and sports-minded people should above all, run well and be resistant to the adverse conditions of the track and surroundings. An easy, quick and uncomplicated cleaning solution is also expected of such bikes. So the bike is often cleaned with high pressure cleaners after being driven through mud, sand and dust. This resulted in an essential requirement in the development of a sealing system for the bicycle's bottom bracket. Here, the sealing system had to withstand high pressure cleaning, in addition to maintain flow and provide anti-corrosive protection to the unit.


Küpper solutions

Using a form-fit mounted corrosion-resistant steel sealing system with molded lip seal. The design ensures a permanent secure roller bearing seal under the force of high-pressure cleaners. The innovative seal design provides an additional sealing effect through its labyrinth form.
