Two in One: Tandem-toothed belt axis

Thanks to the double belt, the ZLWT tandem-toothed belt axis is ideal when several linear slides need to be moved quickly and independently of each other. The motors can be mounted on one or both sides. A parallel synchronised drive is also possible.

Addition to the tandem-toothed belt axis installation size 10/20
Compact tandem-toothed belt axis with two toothed belts in one unit
Two slides can be controlled synchronously or separately
With drylin® W-exchange bearing for quick bearing replacement on the rail
Available ready for connection with igus® electric motors and D1 motor control unit

Typical areas of application: Automation, robotics, assembly cells, painting systems

Sustainability

Two carriages positioned with just one axis
Clean and lubrication- and maintenance-free
Pillow block can be replaced, all metal linear axis components can be re-used throughout the service life

Manual or automated format adjustment

When do I use what?

Numerous possibilities

Still not sure how your lead screw axis should be driven? We present you with various options:

Two manual drives, for example with position indicator and hand wheel
One manual and one electric drive
Two electric drives, e.g. with stepper motor

You can discover the respective advantages on the following slides.

Manual format adjustment

More sophisticated format adjustments are realised with torsion-resistant linear axes. On the one hand, these tolerate Higher forces and, thanks to the hand wheel and position indicator Precise fine adjustment of a desired control value. They are also quickly configured and implemented in the system. Since the operation of manual positioning systems without an actuator can still be time-consuming, this system is only worthwhile if format adjustments in the machine occur less frequently.

Automated format adjustment

Are Format adjustments regularly recurring and in many places In order to fulfil the requirements of the packaging machine, positioning systems with actuator connections become indispensable. Through the Time saving can quickly amortise the higher costs compared to manual systems. With the optional addition of a motor control unit Position several adjustment units synchronously. This also helps to avoid errors.

Testing the tandem-toothed belt axis in the laboratory

The robust design with lubrication-free drylin® W linear plain bearings ensures a long service life and maintenance-free operation. This was confirmed in the igus®-test laboratory.
