The tubular system linear unit for light adjustment tasks is ideal for manual adjustments. The single-tube axes from the easytube product range are available in three sizes. The external anodised aluminium guide tube guides one or more guide carriages and simultaneously protects the threaded spindle and lead screw nut from external influences. The carriage, torque support, spindle thrust bearing and lead screw nut are made from a self-lubricating, high-performance polymer plain bearing. This guarantees a low coefficient of friction and low wear. The easytube single-tube guide is ideal for format adjustments and applications in which the drive elements need to be protected from dust and metal chips.
