ELGD-TB-WD – the new generation of electric toothed belt axes in wide design
The toothed belt axis ELGD-WD-TB with innovative and optimally spaced, precision recirculating ball bearing guide and toothed belt drive is protected by a permanently magnetic stainless steel cover strip. The portfolio includes four wide versions, starting with 100 mm width and expanding to 220 mm. The axis is already available with a maximum stroke of 8.5 m and different slide options.
1. Innovative guide technology developed in-house
- Excellent rigidity
- Guide has exceptional load bearing capacity
- Lightweight
- Precise and smooth, virtually vibration-free slide movement over the entire stroke range up to 2.5m
- Possible to use a smaller size for lower weight, smaller installation spaces and reduced costs
- Virtually vibration-free and very smooth slide movement
- High speeds over the entire stroke range up to 8.5m
- 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
Wide (ELGD-TB-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 the standard profile width
- Overall height reduced by 30%, yet feed forces are similar to the axis with a standard profile height
Standard (ELGD-TB): square profile cross-section with optimised design
4. Various slide options
- Long slide and freely movable second slide
- For higher axial and lateral torques and higher loads
- Additional mounting options
- Longer service life thanks to a second slide that allows the guide load to be distributed
Application example with second slide: simple and flexible dual pick-and-place solution
- Very compact design with two independently moving Z-axes
- Long Z-axis guide for high rigidity, even at high speeds and loads
5. Optimised profile design
- Optimised force flow and torque absorption
- Very high rigidity
- Long strokes of up to max. 8.5m
6. Freely selectable motor positions
7. Different toothed belt materials
- Polyurethane (PU2) with fabric sheath for long service life and greater resistance to cooling and lubricating fluids. Steel cord tension members enable high forces to be transmitted and also allow the axis to be dynamically controlled
- Polyurethane (PU1) without sheath, but with a steel cord tension member for applications in the food zone
8. Optional sensing for greater reliability
- Inductive proximity sensor SIES8M as NC/NO with switching output PNP and NPN and with 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

A powerful axis series with high rigidity, large feed forces and durable guide system
The ELGD axis series is a versatile system in electromechanical automation technology. Spindle and toothed belt drives with different sizes in standard and wide versions can be used for a wide range of tasks, such as pick-and-place applications, 3D contouring for applying adhesive beads, packaging and inspections. The axes are perfect for use in the electronics industry, packaging technology, machine building (e.g. additive manufacturing), the automotive industry and many other application areas.
