Reversing & Disengaging Tandler Spiral Bevel

Featured Product from DieQua Corporation

The Tandler spiral bevel gearbox series “S” and “AS” offer output shaft rotation reversing or disengagement capabilities in a right angle gearbox through the manual actuation of a two or three position spring loaded switch handle. Motion must be completely stopped and the gears unloaded before the handle position can be changed.

This gearbox is ideal for detaching a station from a multi axis machine when not required. Tool changeover or other maintenance operations could also be performed with reduced operator risk.

This box is also available with an optional reverse gear. Jogging out of machine jams, changing web paths for back side printing, main drive changes of direction are just a few possible applications.
