Custom gears, sprockets and machined power-transmission components for rail equipment OEMs, maintenance teams and replacement-part requirements.
Commercial Gear supports new manufacturing and MRO projects with gear cutting, CNC machining and dedicated inspection capabilities.
Built around your drawing.
Rail equipment can remain in operation long after original components become difficult to source. Commercial Gear supports OEM and MRO requirements with custom gear manufacturing, machining and inspection for customer-defined replacement components.
Our capabilities are especially useful when a project involves an existing drawing, a customer-supplied blank or a component that requires additional machining and gear cutting before it can return to service.
Inspection also plays an important role when the problem is not obvious. In one documented railcar application, gears were binding in operation. Commercial Gear’s inspection identified excessive lead and profile error, providing the information needed to address the gear geometry problem.
Rail equipment projects can involve new production, replacement components or existing parts that no longer perform as intended. Commercial Gear brings gear manufacturing, machining and inspection together to support these requirements.
Manufacturing support for new rail equipment production, maintenance and repair programs.
Spur, helical, bevel, miter, worm and internal gears made to customer drawings and specifications.
Replacement gears and sprockets for older equipment when original parts are difficult to source.
Profile, lead, runout and dimensional checks that help diagnose binding, wear or fit problems.
Turning and milling for bores, hubs, shafts, keyways and other component features.
Reboring, keyways, drilling and other machining on appropriate stock sprockets.
Gear cutting on blanks you supply, from single replacements to repeat orders.
Prototypes, one-off replacements, short runs and production quantities.
From custom gears to modified sprockets and machined components, Commercial Gear supports rail equipment projects where accurate tooth geometry, fit and manufacturing consistency matter.
Custom spur, helical, bevel, miter, worm and internal gearing can be manufactured to customer drawings and specifications. Gear cutting is supported by CNC machining and dedicated gear inspection capabilities.
Custom sprocket manufacturing plus modification of stock sprockets, including reboring, keyways, drilling and related machining where required.
Internal and external splines, spline shafts, rack gearing and related machined components for customer-defined industrial equipment requirements.

Questions about custom rail equipment gears, replacement components, sprockets and manufacturing requirements
Yes. Commercial Gear supports MRO and replacement-part manufacturing from customer drawings and specifications. Depending on the project, manufacturing can begin with customer-supplied blanks or include broader machining and gear-cutting operations.
Commercial Gear manufactures spur, helical, bevel and miter, worm and internal gears, along with related gearing and power-transmission components. The appropriate manufacturing process depends on the component geometry and drawing requirements.
Commercial Gear has dedicated gear inspection capabilities for evaluating characteristics such as profile, lead, composite variation and runout. In a documented railcar project, inspection identified excessive lead and profile error associated with gears that were binding.
Commercial Gear manufactures custom sprockets and can also modify appropriate stock sprockets through operations including reboring, keyway machining and drilling. Customers should provide the chain size or pitch, tooth count, bore, hub details and other drawing requirements.
Send the available drawing or CAD file along with material, quantity, tolerances, gear or sprocket specifications, required machining features and inspection requirements. For replacement projects, include information about the mating component and the problem being experienced when relevant.
Yes. We review custom components for new equipment as well as replacement gearing and sprockets for existing rail cars and track maintenance machinery.
