ELGD-BS – The new generation of electric ball screw axes in a standard design
The ball screw axis ELGD-BS with innovative and optimally spaced, precision recirculating ball bearing guide and ball screw is protected by a permanently magnetic stainless steel cover strip. The portfolio offers the main sizes 60/80 mm and will also be available in six standard widths, from 30 to 160 mm. More sizes will follow in 2024. The axis is already available with a maximum stroke of 2.5 m and two slide lengths.
1. Guide technology developed in-house with an optimised design for the electric axis mechanics
- Excellent rigidity
- Guide has exceptional load bearing capacity
- Lightweight
- Precise and smooth, virtually vibration-free slide movement over the entire stroke range up to 2.5 m
- Possible to use a smaller size for lower weight, smaller installation spaces, and reduced costs
- Very long service life
2. Innovative stainless steel cover strip solution
- Magnetic belt deflection without components causing abrasion on the outside
- Clean surface, no abrasion on the outside
- Minimised particle emission for use in cleanrooms
- Reduced ingress of dirt in harsh ambient conditions
3. Two different profiles
Standard (ELGD-BS): square profile cross-section with optimised design
Wide (ELGD-BS-WD): reduced profile height for smaller installation spaces and more compact handling systems
- High torsional rigidity with lower weight and reduced costs
- 30% lighter, while rigidity and load capacity are still similar to the axis with standard profile width
- Overall height reduced by 30%, yet feed forces are similar to the axis with the standard profile height
4. Optional extended slide
- For higher axial and lateral torques and higher loads
- Additional mounting options
5. Optimised profile design for the best force flow and torque absorption
- Excellent rigidity
- Long strokes of up to max. 2.5 m
6. Optional sensing for greater reliability
- Inductive proximity sensor SIES-8M as NC/NO with switching output PNP and NPN and degree of protection IP67
- Easy to mount up to 2 sensors in the profile slot without needing additional mounting components
- Flush mounting without interfering edges outside the drive cross-section
- Sensors can easily be added or repositioned at a later date
7. Freely selectable motor positions
- Motor mounting options: axial or parallel
- Axial: motor can be mounted 4 x 90° around its own axis
- Parallel: a mounting kit can be fitted at 3x90° and the motor can be rotated 3x90° around its own axis
- The axis can be ordered with motor mounting on the right (MR) or left (ML) (MR/ML defines the position of the motor in relation to the central lubrication connections on the slide)

A powerful axis series with excellent rigidity, large feed forces and durable guide system
The axis series ELGD with spindle and toothed belt drive is available in different sizes and in both standard and wide versions, and can perform a wide range of tasks in electromechanical automation technology. The comprehensive portfolio is ideally suited for applications such as pick and place, 3D contouring, e.g. when applying adhesive beads, for loading and unloading, inspection, packaging and sorting. ELGD is ideal for the electronics industry – including cleanrooms – packaging technology, machine building such as additive manufacturing (also known as 3D printing), automotive and many more.
