ZASR
Our precise ZASR series includes rotary swivel axes with preloaded double pinion for payloads from approx. 1,500kg. These two-axis swivel units are driven by spur or bevel gear sets, the choice depending on the spindle arrangement and the available installation space.
The gears are also electrically clamped against each other, making them backlash-free during operation. This makes them particularly suitable for use in reversing axes; direct or worm drives are used for table axes.

Drive type
Pinion drives
Peiseler offers subdevices with preloaded gear sets with spur or bevel gearing. The available space determines the design; usually a multi-stage solution of one of the two alternatives. Compared to the worm gears, gear drives are more complex due to the multi-stage design. Elimination of backlash is achieved by mechanically or electronically tensioning two drive trains. The high torques, speeds and duty cycles are advantageous. Based on their characteristics, gear drives are classified between worm gears and direct drives.
