For the different applications such. For tachographs, NC-axes, stepper motors, potentiometers, robot drives, linear units, handling devices, angle encoders or servo drives, various designs are available. The shaft is fastened by clamping ring or threaded pins. The miniature couplings are available as bellows couplings, elastomer couplings or cross slide couplings. As bellows couplings they are absolutely play and maintenance-free and designed for the transmission of high speeds. They are characterized by a high torsional rigidity and a low mass moment of inertia. Thus, the angular true, backlash-free transmission of the rotational movement is possible. The compact elastomer miniature couplings as pluggable, backlash-free and flexible shaft couplings can compensate for slightly larger shaft offsets. They are electrically insulating and have a good vibration-damping behavior. The advantages of the also electrically insulating cross slide coupling are in addition to a very short length, a large displacement capacity, low restoring forces, the pluggability and a resulting arbitrary combination of different bore diameter. In normal operation, the couplings are maintenance-free and with proper installation, the JAKOB miniature couplings achieve an almost unlimited service life. Due to the proven modular system and the storage of the common diameters shortest delivery times are guaranteed.
