Straight Tooth, Metric, & Inch Miter Gears

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-degree angle. Yet even though 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.

Miter Gear Applications

Miter gear sets are used in applications where the input and output rotational speeds of a drive do not vary, only where a change of axis rotation is necessary.

For applications that require a non-conventional shaft angle, SDP/SI engineers suggest angular miter gears. These gears are available with 45°, 60°, and 120° shaft angles.

Our straight-tooth miter gears are offered in steel, stainless steel, aluminum, brass, and plastic from 72 pitch to 16 pitch and modules 0.5 through 3.5. Our metric spiral miter gears are available in ground steel and S45C steel with heat treatments including overall carburization and induction-hardened teeth with a black oxide surface coating. They are offered in module 1 through module 10.
