Airex Co. Ltd. from Japan had trouble finding a lubrication-free bearing with low dust generation and high chemical resistance for use within the insulator (Class A). In addition, it had to withstand the load of the shelf weight (400kg) and up to 80 syringe sets when tilted.
The result: xiros polymer ball bearings made of xirodur C160 with stainless steel balls. As the ball bearings are lubrication-free, they guarantee the highest degree of cleanliness in the sterile environment. The ball bearings are arranged as scaled rollers to allow the syringe sets to glide.
