Special features:
item products are based on different modular dimensions and their associated system grooves. Profiles from Lines 5, 6, 8, 10 and 12 each need corresponding sizes of fasteners. The profiles in Line X feature a Line 8 system groove but have a particularly flat surface with minimum curve radii that make them ideal for building sealed constructions.
Components that are RoHS-compliant contain no dangerous substances such as lead or cadmium. EC Directive 2002/95/EC (RoHS 1) restricts the use of certain substances in electronic devices and components. These include batteries, etc.
All substances are registered according to the REACH regulation. REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) ensures that users have accurate information on the type and properties of operating materials, lubricants, etc. that they might come into contact with.

Backlashmax.(spindle/drive nut) = 0.04 mm
m = 5 kg + H x 0.011 kg/mm
Ball Screw Units KGT are suitable for use as a drive mechanism for linear slides, particularly for low speeds and short strokes. They feature high precision, high efficiency, high rigidity of the drive system and low mechanical wear:
- For use in linear units, conveyors, handling devices, work bench design and any other fixtures
- Powered by hand wheel, AC/DC motors, stepper motors and hydraulic or pneumatic drive mechanisms
- Choice of power input end
- Can be combined with any type of guide
- Individual components are replaceable
- Full compatibility with MB Building Kit System products
Complete drive units of variable stroke length (H), spindle pitches of 5 mm or 20 mm and drive option via Multi-Spline Shaft or custom machined hubs.
Supporting profile with integrated lip seals, fixed and floating bearing blocks, ball-bearing collet mechanism for holding the spindle, end of stroke damping, secure yoke, play-minimised drive nut suspended on gimbals and rolled spindle.

Grease lubrication
Lubrication interval: Every 400-500 operating hours with lithium-based roller-bearing grease (not general purpose grease)

Max. acceleration = 5 m/s2
Max. stroke length = 2687 mm
Total length L = stroke length + 400 mm
Safety clearance S = 86.5 mm

Suitable for combination with all item linear slides.
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 yoke adapter can be matched to the height of the slide by means of grub screws DIN 913-M5x5.
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.
It is important to ensure that the yoke adapter is aligned to the spindle and profile. The maximum permissible angular deviation must not be exceeded.
Connection dimensions of the Bearing Blocks at the floating (L) and fixed (F) bearing ends. Depending on the drive type selected, the Bearing Blocks and drive holders may need to be machined.
The hub is reborable up to max. ∅ 17 mm or ∅ 14 mm for insertion of a parallel keyway as per DIN 6885 T1.
Direct drive connection with Adapter Plate 120x80. Various drives adaptable using the Adapter Shaft and Adapter Flange Universal.
Parallel arrangement of Ball Screw Units in connection with Bevel Gearboxes.
The service life of the screw and drive nut combination can be calculated based on the thrust load and drive speeds

Applications

Laser welding head - Article EX-01081

This 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.
