The S1C84Z-P048B075Q is a worm gear with 75 teeth, a 0.1873 inch bore, and a quadruple thread, designed for 48 pitch applications. It is made of bronze conforming to QQ-B-637 Alloy 464 and mates with a 303 stainless steel worm. The gear has a 14.5° pressure angle and is compatible with standard 48 pitch worms. The part number format matches the series listed for 48 pitch worm gears, with bore size, tooth count, and thread type identified by the suffix.
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.
