Custom gears, splines, shafts, sprockets and related power transmission components for oilfield drilling, pumping, lifting, handling and processing machinery.
From high-torque drives and pump transmissions to chain-drive and right-angle systems, components are manufactured to your drawings, equipment specifications and operating requirements.
Custom components manufactured in East Walpole, Massachusetts since 1946.
Oil and gas equipment operates through repeated load cycles, high torque, mechanical shock and demanding service conditions. The components inside it must transfer power reliably while maintaining the geometry required by mating shafts, pumps and drives.
Commercial Gear manufactures custom gears, splines, shafts and sprockets for new equipment, established production designs, maintenance requirements and difficult-to-source replacements.
High torque, shock loading and replacement fit all shape the specification. We manufacture to the drawing so the component works inside the machine you already run.

Common questions about custom gears for drilling, pumping, handling and processing equipment.
Oil and gas machinery can use spur, helical, bevel, internal and worm gearing depending on the transmission layout. Splines, shafts, sprockets, rack-and-pinion systems and other mechanical power-transmission components may also be used throughout drilling, pumping, handling and processing equipment.
Custom gearing may be used within top drives, drawworks, mud pumps, pumping units, hydraulic power tongs, winches, hoists, pipe-handling equipment, valve actuators and other petroleum-production or processing machinery.
Commercial Gear can manufacture custom gears, pinions, shafts, splines and related transmission components to customer drawings for pumping equipment applications. The specific component and manufacturing requirements should be submitted for review.
Yes. Commercial Gear can review custom replacement requirements where drawings, specifications or suitable technical information are available. Matching tooth geometry, bore, shaft interface and other mating characteristics is important for existing equipment.
Commercial Gear manufactures the types of custom gears, shafts and splines that may be used within these drive systems. Requirements should be submitted using the component drawing and specifications for manufacturing review.
Yes. Commercial Gear manufactures custom sprockets up to 36 inches in diameter with published pitch capability from ¼ inch through 2 inches.
Commercial Gear manufactures worms and worm gears that can be specified for compact speed-reduction, positioning and actuation mechanisms, subject to the customer's component design and requirements.
Yes. Commercial Gear's quote process supports requirements ranging from a single prototype or specialized component through longer production orders.
Commercial Gear's published capacity includes spur gears up to 36 inches in diameter, internal gears up to 36 inches I.D., and several other gear families up to 16 inches in diameter. Submit the specific print to confirm manufacturability.
Yes. Customer drawings and prints are the preferred basis for quoting custom components. Commercial Gear requests drawings, tolerance requirements, material, quantity, delivery timeline and applicable secondary-process information.
Yes. Commercial Gear provides CNC machining and turning for custom power-transmission components in addition to its dedicated gear-cutting processes.
Provide the component drawing where possible, along with gear specifications, material, tolerances, quantity, secondary-process requirements, application information and required delivery timeframe.
