ELGD-BS-WD – the new generation of electric ball screw axes in wide design
The ball screw axis ELGD-BS-WD 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 includes four wide versions, ranging from 100 mm to 220 mm. The axis is already available with a maximum stroke of 2.5 m and two slide lengths.
7 good reasons to use the ELGD-BS-WD
1. Guide technology developed in-house with optimised design for 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 difficult ambient conditions
3. Two profile variants
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 normal profile width
- Overall height reduced by 30%, yet feed forces are similar to the axis with a standard profile height
Standard (ELGD-BS): square profile cross-section with optimised design
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
- Very high rigidity
- Long strokes of up to max. 2.5 m
6. Optional sensing for greater safety
- Inductive proximity sensor SIES8M 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 3 x 90° and the motor can be rotated 3 x 90° around its own axis
- This axis can be ordered with motor attachment on the right (MR) or the left (ML) side
(MR/ML defines the position of the motor in relation to the central lubrication connections on the slide)
Axial attachment with motor position on the left (ML)
Parallel mounting with motor position on the right (MR)
