Maximum surface quality for flawless functionality
The outer diameter of the ball cup is 1.3 mm with tolerances of ±0.005 mm
Total size
1.3 × 2.0 mm
Zirconium oxide,
the perfect material
Due to its biocompatibility, hardness, corrosion resistance and aesthetics, zirconium oxide is ideally suited for numerous medical applications
The axial bearing for medical pumps has a high precision, spherical inner shape with perfect surface quality
Polished surface on the inner shape with an
Ra value of 0.008 µm
The theoretical radius of the inner shape deviates deviates by a maximum of 0.4 µm
The high surface quality ensures low friction
and therefore high pump efficiency
This is how 32 billion revolutions can be guaranteed
