Shaft to Bore Gearboxes
Shaft to Bore worm gearboxes feature an output shaft at 90? to the input shaft and are designed to transmit torque between shafts that are not intersecting or parallel. These power gearboxes transmit high torque and offer considerable speed reduction in a compact design. Their versatility makes Shaft to Bore gearboxes an effective solution for almost any power transfer application.
