The linear axes are fast, accelerate up to 150 meters per square second and achieve a service life of up to 100,000 kilometers without additional lubrication. In fast-moving single-axis positioning systems in fully automated assembly, handling and packaging lines, they are designed to impress as fire-and-forget solutions that reduce maintenance costs and maximize process reliability. Thanks to their stroke path of up to 1,690 millimetres, high acceleration and top speeds of five meters per second, the HA01 axes, which are available in three sizes, are an option for implementing fast-cycling long-stroke applications. Their repeat accuracy is plus/minus 0.05 millimetres as standard.

An HA01 axis always consists of a tubular linear motor, a guide rail and a compact carriage body with two carriages. These units are strictly trimmed for mass optimization with a short design, narrow carriage body and a single precision rail made of hardened steel. What is not visible from the outside is that the rolling elements in the two recirculating ball carriages move in a "concurrent lubrication system", which is why the axes do not require an additional lubricant supply and are otherwise maintenance-free. Despite the monorail design, the system is resistant to bending and torsion and achieves respectable load torques and peak feed forces of up to 585 newtons.

The axes are equipped with single-cable technology; both the power supply for their servo drive and the signal routing for their travel measurement sensors are provided via a single moving cable. For the long-travel sprinters, Jung only processes semi-finished products in its in-house cable assembly department that have a durability of at least ten million movement cycles over the entire stroke path - i.e. there and back. Jung uses this material to produce just-in-time long-life cable harnesses up to 30 meters long, suitable for towing, according to customer requirements.

Apart from the three sizes of these Highdynamic long-stroke linear axes with construction and slide widths of 44, 60 and 70 millimetres, designers have a choice of options with which the long-stroke sprinters can be tailored to the specific application. pb
