Trunnion tables with worm gearboxes

Our AWU series of trunnion tables offers outstanding solutions for machining large workpieces and high cutting forces.  

The drive of the trunnion table is equipped with a backlash-free worm gear set. We use axial-radial bearings for maximum stability, and additional support bearings are available on the rear of the housing for extra rigidity. The robust cast construction comes with thick walls and strong ribs for optimum damping.  

We are happy to offer you large free center diameters in the face plates to meet your requirements. Get in touch with us!

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.

The benefits for you

  • Simple commissioning/easy installation

  • Easily adjustable worm gear

  • Maximum drive moment and low backlash

  • Self-braking (safety feature)

  • Cost-effective solution for positioning applications
