The efficient linear systems from item enable users to develop automatic solutions of the highest standards. The highly accurate linear slides can be used to connect numerous axes into complete handling and positioning systems.
For example:

item linear technology can be used to design highly accurate 3-axis handling systems. Movement along the X axis is controlled by two synchronised KLE 8. Movement along the Y axis is controlled by roller guide 8 D10 with timing-belt drive, while roller guide 8 D14 with timing-belt drive takes care of the Z axis. This combination of three components can be adapted and modified for all requirements and any basic frames built using the MB Building Kit System.
