Helical gears have slanted teeth that are cut at an angle to the axis of rotation. This helix angle can be up to 45 degrees and can be left- or right-handed. Compared to spur gears, helical gears are quieter and produce less vibration, so they’re often used to reduce gear noise. Since helical gears have thicker teeth, they’re also stronger than spur gears, allowing them to transmit more torque.
PIC’s precision helical gear manufacturing capabilities meet the latest AGMA/ISO specifications, up to the equivalent of AGMA Q14 per AGMA 390.03.

We offer standard aluminum and stainless-steel helical gears available in our catalog. PIC’s custom helical gear manufacturing capabilities include non-standard pressure angles, pitches and materials. We can also provide any helix angle up to 45 degrees for right or left hand.
The following specifications define our standard selection and routine customization options in either right- or left-handed Helical Gears:
- Diametral Pitch: 48 & 64
- Helical Angle: 45°
- Bores: 1/8”, 3/16”, & 1/4”
- Face Width: 1/8” & 3/16”
- Standard Material Options: 303 Stainless Steel, 2024 Aluminum
Other material options are available for custom helical gears
Common Helical Gears Applications
PIC manufactures helical gears for use in a variety of industries including aerospace and military instrumentation, medical, dental, oil and gas, robotics, optical and industrial controls. Some applications within these industries include precision positioning, rotational drive encoders and other similar light-duty applications. Since helical gears produce end thrust on the mounting shafts, they often require the use of thrust bearings.
