Pivot Bearing

Aluminium

Aluminium components reduce weight by up to 50%. Especially when it comes to the chassis/suspension components, unsprung masses are significantly lowered as a result. This has a positive influence on the driving comfort and the handling dynamics. Forged, high-strength and high-toughness components that permit significant deformation for safety reasons are particularly difficult to machine. They require an appropriate tool concept with good chip control
