Suppliers of gear manufacturing services design and fabricate gears to customer specifications.  Suppliers of gear manufacturing services have the capability to manufacture many types of gears.  These include anti-backlash gears, bevel or miter gears, change gears, cluster gears, differential gears, gear blanks, gear stock or pinion wire, helical gears, herringbone gears, hypoid gears, internal gears, planetary gearing, racks, spur or pinion gears, and worms and worm gears. 

Anti-backlash gears have gearing designed to take up or eliminate backlash between gears, typically with a spring or other mechanical assist.  Bevel or miter gears are conical face gears that operate on intersecting axes, which are often at right angles.  Change gears resemble spur gears.  They are hubless with a keyway that mates with a hub for rapid changing (used in machines where gear ratios are changed frequently).  Cluster gears are spur gears with integral hub whose end can accept a second, hubless gear.  Differentials are gears and gear assemblies that transfer power from a single drive shaft to two wheels, typically on an axle perpendicular to the drive shaft.  The differential allows the wheels to be driven at different speed to avoid wheel or tire scuffing during turning.  Central to automotive and other vehicle power train design.  Gear blanks have the hub and O.D. already formed.  They may be hobbed or ground to any tooth configuration.  Gear stock or pinion wire is a length of rod with gear teeth already furnished for custom width machining.  Helical-toothed gears transmit power and motion between parallel axes (opposite hand) or right-angle axes (same-hand).  On herringbone gears each tooth comprises two opposing helices. They transmit power and motion between parallel axes.  They may or may not have center groove.  Hypoid gears are similar to a bevel gear, but hypoid gears are driven by a worm-like drive on non-intersecting axes.  Internal gears typically have straight teeth on ID with circular OD.  Internal gears mate with spur gears on the inside.  Planetary gearing has a gearing arrangement comprising a central or "sun" gear, multiple "planet" gears that surround and are driven by the sun gear, and typically an internal gear driven by the planet gears.  Racks are straight component with gear teeth; typically straight-toothed.  They mate with pinion (spur gear) for linear-rotary power transmission.  Worms are screw-like devices whose spiral teeth mate with the teeth of a round worm gear or worm wheel.  Typically the worm is driven, and the worm wheel transmits power at a non-intersecting 90° axis.

Other product capabilities include the ability to manufacture brakes and brake parts, chain drives, clutches, gages and masters, gearboxes and transmissions, impellers, industrial drives, rollers, splines, sprockets, timing pulleys or synchronous drives, and v-belt pulleys, sheaves, and drives.  Common manufacturer capabilities of suppliers of gear manufacturing services include design and development, failure analysis, inspection and testing, just-in-time, prototypes, production manufacturing, repair or reconditioning and reverse engineering.  Secondary options often include broaching, casting, gear shaving, grinding, heat-treating or hardening, hobbing, lapping or honing, and surface finishing. 

Certifications and quality standards often adopted by suppliers of gear manufacturing services include AS9000, QS 9000, ISO 9001, ISO 9002, and MIL-SPEC / STD.  Materials of construction can be aluminum, brass, bronze, cast iron, powder metal, steel, hardened steel, stainless steel, and titanium.  Plastic and other materials include acetal, ceramic, nylon, phenolic, polycarbonate, reinforced plastic or FRP, and rubber or rubber compounds. 

Specialty industries served by suppliers of gear manufacturing services include general industrial, aerospace, automotive, construction, heavy transportation, HVAC or refrigeration, machine tool, marine, material handling or conveying, medical or pharmaceutical, military, mining, petrochemical, power generation, pulp and paper, pumping, robotics, and wastewater.
