S13S1YMK30G25R20 is a right-hand spiral miter gear with module 3, 25 teeth, and a 20 mm bore. It has a pitch diameter of 75 mm, face width of 20 mm, and a helix angle of 35°. The gear is made from AISI 1045 steel with tooth surfaces induction hardened to HRC 48-53 and finished with black oxide, except for the ground bore and tooth surfaces. The hub diameter is 75 mm, hub length is 20 mm, and the axial projection from the back of face to center of bore is 37.43 mm.
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.
