The S13S1YMK25G30L16 is a left-hand spiral miter gear with a module of 2.5, 30 teeth, a 16 mm bore, and a 78.04 mm pitch diameter. It features a 35° spiral angle, 20° pressure angle, and is made from AISI 1045 steel with induction-hardened tooth surfaces rated at HRC 48-53. The gear has a black oxide finish except on the ground bore and tooth surfaces. Dimensions include a 60 mm face width, 62 mm hub diameter, 7 mm hub project, and 17 mm distance from back of hub to bore center. The gear is designed for use in pairs with an opposite-hand gear to transmit motion at 90°.
Standard straight-tooth miter gears are a type of bevel gear set that has a 1:1 ratio, identical dimensions, and the same number of teeth, allowing them to mate with one another and transmit rotational motion at a 90° angle. Although the number of teeth in a spiral miter gear set is the same, the twisting directions are different, preventing them from mating with one another. Our straight-tooth miter gears are manufactured utilizing a CNC Coniflex® interlocking cutting system. Spiral miter gears must be paired with one right-hand thread and one left-hand thread.
