The A 1C 5MYK15RC is a right-hand steel worm with a module of 1.5, single thread, 25 mm pitch diameter, and a 43 mm length. It has a 20° pressure angle, a 12 mm bore with H8 tolerance (+0.027/0 mm), and a keyway with 10 mm hub projection and 4 mm width. The worm features a 1.8 mm diameter keyway slot and is designed to mesh with compatible right-hand worm gears.
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.
