Capabilities
   Gears       
   Your choices are...         
   Anti-backlash Gears       Gearing designed to take up or eliminate backlash between gears, typically with a spring or other mechanical assist. 
   Bevel / Miter Gears       Conical face gears that operate on intersecting axes, which are often at right angles. 
   Change Gears       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       Spur gears with integral hub whose end can accept a second, hubless gear. 
   Differential Gears       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 powertrain design. 
   Gear Blanks       Gear blanks have the hub and O.D. already formed.  They may be hobbed or ground to any tooth configuration. 
   Gear Stock / Pinion Wire       Length of rod with gear teeth already furnished for custom width machining.

   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       Similar to a bevel gear, but hypoid gears are driven by a worm-like drive on non-intersecting axes. 
   Internal Gears       Typically straight teeth on ID with circular OD.  Internal gears mate with spur gears on the inside. 
   Miniature Gears       Miniature gears require precision machining operations on small parts to achieve intricate details. 
   Planetary Gearing       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.  Useful for good power transmission efficiency in a compact, in-line gear train application. 
   Racks       Straight component with gear teeth; typically straight-toothed.  They mate with pinion (spur gear) for linear-rotary power transmission. 
   Spur / Pinion Gears       Spur gears are straight-toothed and transmit power and motion between parallel axes. 
   Worms and Worm Gears       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.  Worm gear drives are often used for high torque, high reduction ratio drives; they are also compact is size.

Materials
   Metals:       
   Your choices are...         
   Aluminum       Refers to many aluminum alloys used as light-to-medium duty industrial components that have good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.  Aluminum alloys are typically non-magnetic. 
   Brass       Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability. 
   Bronze       Copper alloy used widely in general industrial applications.  Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Not suitable for heavily loaded applications but useful where lubrication is inconvenient. 
   Cast Iron       The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. 
   Magnesium       Magnesium and magnesium alloys are non-ferrous metals with low density (relatively high strength to weight ratio), good ductility, moderate strength, and good corrosion resistance. Magnesium and magnesium alloys are used in a variety of industries as well as in aircraft, marine, and power tool applications. 
   Powder Metal       The powder metal (PM) process uses pressure and heat to form precision parts and shapes. The process begins by filling a die with powder and then compacting it at room temperature to form an engineered shape like a gear. Next, this compacted shape is ejected from the press and fed through a high-temperature furnace. This process, called sintering, metallurgically fuses the particles without melting them.  After sintering, the gear or other component is finished with processes such as machining, grinding, hobbing, etc. 
   Steel       Any of the very numerous commercial iron grades that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.  General use industrial gear material. 
   Steel - Hardened       Steel may be hardened in a number of ways, including a variety of quenching techniques in oil and water, being passed through induction chambers, etc. Quickly cooling steel during processing freezes, traps and packs the carbon atoms inside the shrunken iron crystals, thereby producing a very hard and brittle metal. Although very hard, it cannot absorb much shock or impact without breaking. 
   Steel - Stainless       Stainless steel is chemical and corrosion resistant; typically less hardenable than non-stainless alloys, and often non-magnetic. 
   Titanium       Titanium is known for its lightness, strength, and corrosion resistance.  For this reason it is used widely in the aerospace industry and the medical fields.  When alloyed with other metals, especially steel, it adds strength and oxidation resistance. 
   Other Metal       Other unlisted metal material.
