Build-to-print gears, sprockets, splines, shafts and custom power transmission components for Original Equipment Manufacturers.
From a new component entering production to an established machine requiring dependable repeat orders, we manufacture to your drawings, specifications, tolerances and application requirements.
Custom gears and sprockets manufactured in East Walpole, Massachusetts since 1946.
An OEM component becomes part of someone else's finished machine. Dimensions need to match the drawing, mating components need to engage as intended, and production parts need to stay consistent from one order to the next.
Commercial Gear manufactures custom spur, helical, bevel, worm and internal gears, racks, splines, sprockets, timing pulleys, ratchets, lead screws and CNC-machined components—from prototypes through repeat production.
Prototype, short run, repeat production or long-run programs—components manufactured to the print, so your equipment design stays the way you engineered it.
Founded in 1946; a third-generation, family-owned American gear manufacturer.

Common questions from OEM engineers and purchasing teams about build-to-print gears and repeat production.
OEM gear manufacturing involves producing gears and related power-transmission components to the specifications of an Original Equipment Manufacturer. The finished component becomes part of the OEM's machinery, equipment or mechanical assembly rather than being sold as a generic replacement part.
Yes. Commercial Gear works with customer drawings and specifications to evaluate and manufacture custom gears and related components. Providing a detailed print helps define tooth geometry, dimensions, material, tolerances and secondary-process requirements.
Commercial Gear accepts requirements ranging from individual prototypes to longer production orders. Prototype quantities can therefore be discussed as part of a new OEM component requirement.
Commercial Gear manufactures spur, helical, bevel and miter, worm and internal gears, along with rack and pinion, splines, sprockets, timing belt pulleys, ratchets, jaw clutches, worms and lead screws.
Yes. Commercial Gear works with OEM and industrial customers requiring production components manufactured to defined drawings and specifications. Repeat requirements should reference the appropriate controlled part information and current drawing revision.
Commercial Gear maintains both dedicated gear-cutting equipment and CNC machining capability. Depending on the component, manufacturing may include turning or milling operations in addition to gear cutting.
Yes. Commercial Gear manufactures internal gears as well as internal and external splines. Its published capability includes internal gears up to 36 inches I.D. and internal or external splines and shafts up to 36 inches long.
Yes. Custom sprockets can be manufactured around OEM-specific tooth, bore, hub and mounting requirements. Commercial Gear's published manufacturing range includes sprockets up to 36 inches in diameter with pitches from ¼ inch through 2 inches.
Where available, provide the component drawing, gear type, tooth geometry, material, dimensional tolerances, quantity, required secondary processes and delivery requirements. Application or mating-component information can also be useful where it affects the manufacturing requirement.
Commercial Gear can review custom component requirements for established equipment where usable drawings, specifications or other technical information are available. This can support ongoing production, service and replacement-part requirements.
Yes. Commercial Gear maintains dedicated equipment for gear profile, lead, composite, bore, runout, bevel gear and other dimensional inspection requirements.
Commercial Gear manufactures custom gears and sprockets in East Walpole, Massachusetts, and identifies its products as Made in America.
