Ball Screw Unit KGT 20x20, VK14Art. No.: 0.0.414.32
|Laser welding head - Article EX-01081This high-precision linear solution can guide a laser welding head to exactly where it is needed. The heavy-duty linear guide system PS 4-25 with timing-belt drive controls movement along the X axis. Ball Screw Unit KGT controls movement along the Z axis.
|Stable test stationThis stable and precise handling station can be used to move even heavy loads accurately and safely along a vertical axis.

Supporting profile with integrated lip seals, fixed and floating bearing blocks, specially designed ball-bearing collet mechanism for holding the spindle, end of stroke damping, secure yoke, play-minimised drive nut suspended on gimbals, rolled spindle, grease lubrication
Lubrication interval: every 400-500 service hours with lithium-based ball-bearing grease (not general purpose grease)
Accelerationmax. = 5 m/s2
Stroke length max. = 2687 mm
Total length L = stroke length + 400 mm
The necessary guidance for the yoke must be provided by the external linear slide.
The driving nut is suspended on gimbals to prevent strains and allow for slight errors in alignment with the load.
The Ball Screw Unit KGT can be driven from the fixed or floating bearing end.
The Ball Screw Unit should be positioned so as to ensure that the main load is a tensile load from the fixed bearing end (i.e. fixed bearing at the top in a vertical unit).
The maximum stroke velocities of the Ball Screw Unit depend on the spindle length (see diagram opposite).
Under axial compression, the buckling behaviour of the spindle must be taken into consideration.
The position of the connecting thread M8 for securing the slide can be either central or offset relative to the slide depending on the position the yoke adapter is used in.
