Shafts for oil mist separators

Oil mist separators are used in trucks and personal vehicles, and they contribute to a cleaner environment. Shafts are mostly produced in medium & high-serial volumes and in different materials, such as free cutting steel and stainless steel. The grinding of the shafts is important to achieve the requested tolerances and is important for us to have fully automated processes with 100% quality control.

Some of the shafts are overmoulded in our plastic division.
