ELGD-TB – the new generation of electric toothed belt axes in Normal version
The ELGD-TB toothed belt axis with internal double-sided recirculating ball bearing guide and toothed belt drive is protected by a permanently magnetic stainless steel cover strip. The portfolio includes 6 Normal versions from 30 to 160 mm width and starts with the main sizes 60/80. Further sizes will follow in 2024. Already available are a maximum stroke of 8.5 m and different slide options.
1. Innovative guidance technology developed in-house
- High rigidity
- Guidance with above average high resilience
- Low weight
- Precise and smooth, almost vibration-free slide movement over the entire stroke range up to 2.5 m
- Downsizing possible: lower weight, smaller installation dimensions, reduced costs
- Almost vibration-free and very smooth slide movement
- High speeds over the entire stroke range up to 8.5 m
- Very high life time
2. Innovative stainless steel cover strip solution
- Magnetic belt reversal without rubbing components on the outside
- Clean surface, no abrasion on the outside
- Minimized particle emission for use in cleanrooms
- Reduced penetration of dirt in difficult ambient conditions
3. Two profile variants
Normal (ELGD-TB): square profile cross-section with optimized design
Wide (ELGD-TB-WD): reduced profile height for smaller installation dimensions and more compact handling systems
- High torsional stiffness with lower weight and reduced costs
- 30% lighter, stiffness and load capacity nevertheless similar to the axis with normal profile width
- Overall height reduced by 30%: Feed forces nevertheless similar to axis with normal profile height
4. Various slide options
- Long slide and second free-moving slide
- For higher axial and lateral forces and higher loads
- Additional mounting options
- Reduced, split guide loads with second slide for longer service life
Application example with second slide: simple and flexible dual pick-and-place solution
- Very compact design with independent movement of both Z axes
- Long Z-axis guide for high rigidity even at high speeds and loads
5. Optimized profile design
- Force flow and torque absorption optimized
- Very high rigidity
- Long strokes up to max. 8.5 m
6. Freely selectable motor positions
- Freely selectable at two positions at the end of the axis
- Motor with cable connection can be mounted in 4 x 90° around its own axis
- Position can be changed at any time
- Define an attachment variant with part number as standard and subsequently convert to alternative positions if required
7. Different toothed belt materials
- Polyurethane (PU2) with textile coating for long life and higher resistance to cooling lubricant fluids. Steel tension members enable transmission of high forces and very good dynamic controllability of the axis
- Polyurethane (PU1) without sheathing but with steel tension member for food applications
8. Optional sensing for greater reliability
- Inductive proximity switch SIES-8M as NC/NO contact with switching output PNP and NPN in protection class IP67
- Simple mounting without additional mounting material of up to 2 sensors in the profile groove
- Flush mounting without interfering edges outside the drive cross-section
- Sensors can easily be added or repositioned at a later date

A powerful family of axes with high rigidity, large feed forces and durable guiding system
The ELGD axis family and its various spindle and toothed belt drives in Normal and Wide versions can be used to perform a wide range of tasks in automation technology. Whether pick-and-place, 3D web travel or packaging and inspection processes, ELGD offers a wide range of possibilities. Ideal for electronics industry (also in cleanroom), packaging technology, mechanical engineering (including additive manufacturing, also called 3D printing) as well as automotive industry and many other application areas.
