S1D94Z-P048SD is a 48-pitch, double-threaded right-hand worm made of 303 stainless steel with a bore of 0.1873 inch, a lead of 0.1309 inch, a 20° pressure angle, and a lead angle of 7°7'. It mates with a 64-pitch worm gear and uses a #4-40 screw thread.
A worm gear pair, or worm gear set, consists of two gears: the worm, which resembles a spiral screw, and the worm gear (aka, worm wheel).
For the pair to mesh, the worm and worm gear must have the same pressure angles, modules, and lead directions (left- or right-hand).
A worm revolves on a shaft that’s perpendicular to the worm gear and the shaft angle is typically 90°. Because the teeth gradually mesh as the worm rotates, there is low noise and low vibration.
