Belt Driven Modular Actuators have a distinct advantage due to there ability to me manufactured in virtually any length. Multi Axis Actuators have the advantaage of simplisity. Pre-engineered to provide by-directional movement accross two or more planes.
The Belts are made of a high tension steel material that only requires a single adjustment after initial use. No further tensioning is required. The pulleys have maintenance free ball bearings. Belt tension can be readjusted by a simple screw adjustment device in the carriage.
