Similar to spur gears, helical gears are also used with parallel shafts, but the teeth of a helical gear are cut at an angle to the axis or hole. Helical gears and spur gears are very similar except that the teeth of a helical gear are cut at an angle to the axis or hole.

Compared with other kinds of gears used for similar applications, these teeth typically engage more slowly and smoothly because the load is transferred gradually and evenly, resulting in incredible quietness and excellent performance. Helical gears come with both left-hand and right-hand twisting options.

Application: reducers, CNC machine tools, robot joints, medical machinery, automobiles, etc.

Available material: steel, hardened steel, stainless steel, aluminum, aluminum alloy, brass, copper, copper alloy, bronze, nylon, non-metallic (phenolic).
