Solution
Airex decided to use special
xiros deep groove ball bearings made of xirodur C160 material to implement the roller tables in the insulator. The advantage of the ball bearings is their lubrication-free operation due to the material. This ensures maximum cleanliness in the sterile environment. In addition, xirodur C160 is resistant to chemicals and can be used at temperatures from 0°C to +60°C. As the material also has low media absorption, it is often used, e.g. in the vacuum in autoclaves. The special bearings are also used in the food industry, electroplating and the semiconductor industry.
In the insulator, the
xiros ball bearings are arranged as staggered rollers at regular intervals to allow the syringe sets to slide maintenance-free. To tilt the tables with the syringes, shafts were also installed at the right and left ends of the insulator, which are supported at both ends by two
igubal pillow block bearings. Here, too, the material allows permanent use in the cleanroom environment.
