HIWIN right-left ballscrews enable the synchronous movement of two ballscrew nuts on a single shaft. The right-hand and left-hand threads are type-specific and are formed on a continuous, one-piece shaft. This results in a particularly compact, rigid and precise solution for synchronous adjustment, clamping and centring tasks.
Thanks to the transmission of force via circulating balls, right-left ballscrews offer high positioning accuracy, high efficiency and a long service life, even under demanding operating conditions.
Our experienced engineers will guide you through every stage, from sizing and engineering right through to commissioning, and will assist you in the selection of the optimal solution for your application.
When are right-hand and left-hand ballscrews used?
Right-left ballscrews are particularly suitable for applications in which two elements need to be moved towards or away from each other in synchronisation. Typical tasks include clamping, centring, gripping and positioning movements in mechanical and plant engineering. They are used wherever counter-rotating movements need to be achieved with high precision and using a single drive.
What customised types does HIWIN offer for right-hand and left-hand ballscrews?
Every application has its own specific requirements in terms of travel distance, precision, load capacity and installation space. To meet these requirements as effectively as possible, HIWIN offers right-hand and left-hand ballscrews with a wide range of customisation options to ensure a perfectly tailored solution.
Possible customisations:
- Custom leads
- Customised spindle end machining
- Various nut designs
- Customised bearing concepts
- Fully integrated system solutions
How does a right-hand/left-hand ballscrew work?
In a right-left ballscrew, both a right-hand and a left-hand thread are located on a single shaft. If two ballscrew nuts are positioned on these threaded sections, they move synchronously towards or away from one another when the shaft is rotated. This allows opposing adjustment movements to be achieved with just a single drive. This reduces design complexity, saves installation space and ensures that both nuts move in synchronisation at all times. Compared to solutions with multiple drives, this simplifies the design and significantly reduces the effort required for alignment.
What are the advantages of HIWIN’s right-hand and left-hand ballscrews?
By combining right-hand and left-hand threads on a continuous, one-piece shaft, right-left ballscrews enable synchronous adjustment, clamping and centring movements using just a single drive. This reduces the space required, simplifies the design and ensures a high level of process reliability.
Your benefits:
- Synchronous movements using just a single, continuous, one-piece shaft.
- Fewer components and reduced design effort
- Space-saving and cost-effective machine designs
- High positioning accuracy and repeatability
- Customised sizing for loads, travel distances and installation situations
- Reduced maintenance and adjustment requirements
Where are right-hand and left-hand ballscrews used?
Right-left ballscrews are used wherever synchronous and counter-rotating adjustment movements are required. They enable the precise movement of two components using just a single drive, thereby offering a compact and cost-effective alternative to solutions with multiple axes or drives.
Typical applications include:
- Clamping systems
- Centring systems
- Format adjustments
- Gripper and handling systems
- Adjustment mechanisms
- Packaging machines
- Automation systems
- Special-purpose machinery
Frequently Asked Questions about Right-Hand Ballscrews
What is a right-left ballscrew?
A right-left ballscrew combines a right-hand and a left-hand thread on a single shaft. This allows two ballscrew nuts to move synchronously towards or away from each other.
What is the difference between a standard ballscrew and a right-left ballscrew?
What advantages do right-left ballscrews offer over two separate drives?
Using just one shaft and one drive reduces the installation space required, the number of components and the effort involved in alignment. At the same time, the movements of both nuts remain permanently synchronised.
For which applications are right-left ballscrews particularly suitable?
Right-left ballscrews are particularly suitable for clamping systems, centring systems, format adjustments, gripper and handling systems, as well as other applications where two components need to be moved synchronously in opposite directions.
Can right-left ballscrews be of a custom type?
Yes. HIWIN offers customised solutions regarding shaft lengths, leads, spindle end machining, nut designs and bearing concepts.
Are there suitable bearing units for right-left ballscrews?
Yes. HIWIN offers optimally matched bearing units and provides support in the sizing of the entire system.
