Med tech compatible material
21 August 2023
IGUS IS expanding its range of high-performance plastics for medical technologywith xirodur MT180, a material for lightweight, lubrication-free, and hygienic xiros deep groove ball bearings – certified to the strictest standards including USP Class VI and DIN EN ISO 10993. Because the material has certified biocompatibility, manufacturers of medical technology such as bioreactors can select certified bearings and save time and money when approving their products.
In medical and pharmaceutical technology, machinery and plant manufacturers are increasingly replacing metal components such as deep groove ball bearings with mating parts made of high-performance plastic. The advantage of using igus’ xiros series ball bearings is that they run without lubrication, are maintenance-free yet also low-friction and hygienic.
Single row xiros deep groove ball bearings made of xirodur MT180 consist of four components: an inner and outer race, a cage, and balls. The cage and bearing races are injection moulded from xirodur MT180, and the balls are made of stainless steel or glass. Glass ball bearings are completely non-magnetic and electrically insulating, so they are also suitable for use in magnetic resonance imaging (MRI) applications.
