cb precision componentsTolerances down to the micrometer range

Since 1965 we have manufactured vanes and subassemblies for vane pumps in vehicle power-steering systems. cb is a worldwide leading large-scale supplier in this sector. The product range is being continually extended due to new developments in the automotive industry.


Numerous different types of steel – such as bearing steel and high-speed steel – are used in the production of these vane-pump components with their diverse radii. The dimensions are equally varied – all the way down to the tiniest pump vanes ever built!

Rotors and complete subassemblies for vane pumps

From cb you not only get individual components but also entire subassemblies – and you can rely on their function one hundred percent!


For these filigree components for roller vane pumps, minimal length tolerances and precise right angles are of key importance – and are a daily task in cb production. It's worth remembering that we produce the tiniest versions ever made!
