A 1M 6-Y48030 is a 48-pitch, 30-tooth, right-hand worm gear made of acetal, with a pitch diameter of 0.625 inch, outside diameter of 0.667 inch, face width of 7/16 inch, bore diameter of 0.187 inch, hub length of 3/16 inch, and hub projection of 1/2 inch. The gear is designed to mesh with standard steel or brass worms at a 90° angle and is intended for use in applications requiring quiet, smooth motion transmission. This part is marked for discontinuation upon depletion of stock.
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.
