## Description

Our patented Screw Gear technology have been used in robotic joint applications for artificial limbs. Its high precision allows for accurate adjustment of rotary and/or linear motions involved with the range of movement (ROM) of an artificial limb. This precision Screw Gear is available in a variety of standard sizes, or can be made to order for custom needs. It is capable of fine adjustment and positive positioning at a cost considerably less than special order mating worm gears. Multiple Motion Capability Due to its simple nature, Screw Gear can be driven from either the screw (worm gear), or the gear itself (rack and pinion / spur gear), allowing for forward & reverse motion capabilities all from one gear. Fine Adjustment & Space Saving The Screw Gear is great for adjustment applications in tight areas. It's capable of precision adjustment and positive positioning. Save Time and Money Because of its machine screw compatibility, you can finish your project faster and at a cost considerably less than special order mating worms. According to design engineers and medical equipment manufacturers, this gear solved one of their toughest mechanical engineering problems, in a minimum available space. The Screw Gear has been used to drive artificial arms and legs, align lasers in the F16 fighter jets, calibrate X-rays, infrared cameras, and many other medical and industrial applications.

## Features

- Capable of BOTH rack & pinion spur gear movement AND precision worm gear adjustment.
- Works with any STANDARD SCREW or THREADED ROD.
- Cost-Effective Value Engineering Design.
- The Screw Gear has a rolling contact which creates LESS FRICTION, WEAR, & HEAT versus the worm gear sliding contact.
