It features a double-helix V-shaped tooth layout that provides smooth engagement while completely neutralizing or self-canceling axial thrust loads.

While single-helical gears generate side (axial) thrust that requires specialized thrust bearings, herringbone gears cancel out these opposing forces internally.

Their continuous tooth contact and high load-sharing capability allow them to transmit massive torque smoothly with reduced vibration and lower noise levels than spur gears.

They are typically manufactured from forged high-tensile alloy steel (such as chrome-molybdenum steel) that is precision-machined and surface-hardened.

Because of the V-shape meeting at a central apex, they tend to self-center axially during operation, though high-precision manufacturing is essential for proper meshing.
