ELGD-BS-WD – the new generation of electric ball screw axes in Wide version
The ball screw axis ELGD-BS-WD with internal double-sided recirculating ball bearing guide and the drive with recirculating ball screw is protected by a permanently magnetic stainless steel cover strip. The portfolio includes 4 Wide versions, starting with 100 mm width and will be extended up to 220 mm. Already available are a maximum stroke of 2.5 m and two slide lengths.
7 strong arguments for ELGD-BS-WD
1. Guidance technology developed in-house with optimized axis design for electric axis mechanisms
- 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
- 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
Wide (ELGD-BS-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
Normal (ELGD-BS): square profile cross-section with optimized design
4. Extended slide optional
- For higher axial and lateral forces and higher loads
- Additional mounting options
5. Optimized profile design for best force flow and torque absorption
- Very high rigidity
- Long strokes up to max. 2.5 m
6. Optional sensing for greater reliability
- Inductive proximity switch SIES8M 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
7. Freely selectable motor positions
- Motor mounting options: axial or parallel
- Axial: motor can be mounted rotated in 4 x 90° around its own axis
- Parallel: mounting kit can be mounted in 3 x 90° and motor can be rotated in 3 x 90° around its own axis
- Axis can be ordered with motor attachment on right (MR) or left (ML) side
(MR/ML defines the position of the motor in relation to the connections of the central lubrication on the slide)
Axial attachment with motor position left (ML)
Parallel attachment with motor position right (MR)

A powerful family of axes with high rigidity, large feed forces and durable guiding system
The ELGD axis family with spindle and toothed belt drive in different sizes is versatile in automation technology. Pick-and-place applications, 3D travel when applying adhesive beads as well as loading and unloading operations, inspections and packaging are all easily possible with the wide portfolio in Normal and Wide versions. The axes are perfectly suited for areas such as the electronics industry, packaging technology, mechanical engineering (including automation for additive manufacturing & 3D printing), the automotive industry and more.
