Ondrives.US Corporation, formerly Rino Mechanical Precision Worm & Wormwheels (Inch)

Ondrives.US has been manufacturing worm and wheel gear systems for over 30 years. We offer worms and worm gears sets in a variety of inch and metric sizes and with numerous pitch, tooth count, and hub options. Our precision ground stainless steel worm and wheels and phosphor bronze worm gears provide the best accuracy, smoothest operation, and longest working life. Available: 16,24,32,48 or 64 Diametral Pitch Standard worm gear worm wheels feature straight, helical-cut teeth and provide only one point of contact with the worm. Ondrives.US offers “throated” worm wheels with curved, helical-cut teeth whose curves match the radius of the worm itself. Throated worm wheels provide a much greater contact area, which vastly improves load capacity and longevity.
