Guiding and positioning
Positioning any moving object requires the transfer of power and overcoming friction. For millenniums, mankind used rollers and skates for this purpose. But how modern linear guidance works?
Linear technology represents the interface between stationary and moving parts. It has the function of power transfer, machine guidance and precise positioning. Linear guidance can essentially be classified according to the nature of the movement and the contact zone. Therefore, movement can be accomplished along the axis or rotation around the axis - and it is called linear or rotational guiding. The nature of the point of contact defines a subdivision to a finishing, sliding and magnetic guiding.
Rolling elements are fast and bear high loads while sliding have excellent damping characteristics and magnetic guidance is characterized by a long lifetime. However, the latter is a special case and is rarely used in practice.

Linear motion systems
Electromechanical cylinders EMC
The mechanical system in the electromechanical cylinder is based on proven planetary or ball coupling spindles with a wide range of combinations of diameters and steps. The coil spindle converts the torque into linear motion with high mechanical precision. During this process, the piston rod secured to the spindle nut is pulled out and retracted. Both nuts and pistols are guided inside the housing and no twisting can occur. Optional end switches serve to limit the running of the cylinder during operation. Thanks to grease lubrication, EMC requires minimal maintenance at longer time intervals.

Planetary spindles PLSA
Planetary transmission spindle PLSA is a set made of planetary gear units as rolling elements. Rope spindles with planetary gearboxes are designed for the transmission of large forces. Rolling rollers are located in the housing of the spindle nut, whose ends are in discs with circularly arranged holes so that they can rotate in parallel with the axis of the spindle causing the linear movement of the nut along the coil spindle.
