The mechanization and automation of linear motions are benefiting from ongoing development efforts, the trend being towards higher speeds, greater load-handling capacities (masses), enhanced precision, quieter running and maintenance-free and quiet operation over the long term, all coupled with low susceptibility to failure. A multitude of drive concepts is available to power linear motions; all are adapted to suit specific requirements and incorporate a variety of mechanical drive elements – such as toothed racks, threaded spindles and synchronous belts. Since no single element is capable of satisfying all the requirements equally well, the selection will be based upon the properties which promise the greatest overall benefit to the user; synchronous belts are gaining significance here due to their many and varied product advantages.
