The AWU trunnion tables series is equipped with a horizontal rotation axis and a vertical face plate for machining larger workpieces and for heavy-duty cutting applications. Driven by a worm gear set as standard, we can also incorporate a belt-driven adapter drive on request. The AWU series is fitted with YRT bearings, with the maximum bearing diameter forming the basis for the design. For maximum rigidity, additional support bearings are available for the rear of the housing. The cast housing is designed with thick walls and strong ribs. We would be happy to provide our design for large face plate through-hole requirements.

Drive type
Worm gear drives
Peiseler uses three-piece worm gears, a well-known design developed by Ott. These gears consist of a worm wheel and a two-piece worm, the shank worm and hollow worm. During assembly, we adjust the gear so it is backlash-free. Readjusting the worm during its service life is simple with a commercially available mounting tool. The design advantages are a compact gear ratio, high mechanical precision and the control's excellent regulatory quality. Heat limits the duty cycle.
