Range of application

The Nearly every automobile manufacturer is in the processof downsizing its passenger cars’ engines. Small displacement engines are lighter and have reduced friction loss, thus making them more fuel efficient and able to meet more stringent emission limits. 

To achieve this technically, tomorrow’s crankshaft bearings will need to have smaller diameters and lengths, and will often need to be harder — resulting in higher stresses and strains due to increased pressures. Thus, the surfaces of the main and pin bearings will require more precise microgeometry. 

Rising to this manufacturing challenge, Supfina has created a new machine line: the Supfina CenPro S. It combines high workpiece quality with short cycle times, not to mention a smaller footprint and lower operating costs.
