LINEAR ACTUATORS - BACKFLASH-FREE AND WEAR RESISTANT R+W COUPLINGS

Speed and precision requirements are constantly increasing for servo and stepper motor driven linear actuators. The reason for this is the shorter cycle times for efficient optimization of processes. As a result, acceleration times and travel speeds are being constantly improved. Alignment errors of individual guides can lead to an increase in loads on the bearings while at the same time reducing precision.

The backlash-free and wear resistant couplings by R+W can help in this case. Synchronization of two parallel linear units is achieved by using a maintenance-free intermediate line shaft. For direct connections with a servo motor, it is possible to choose between torsionally rigid or vibration-damping couplings, depending on the application requirements.
