Precision Gearbox Component Forgings
Gearbox components transmit power at high speed under continuous load — demanding the superior fatigue resistance, dimensional accuracy and surface hardenability that only forged alloy steel can deliver. Our gearbox forgings are manufactured for automotive, industrial and wind energy drivetrain applications.
Gearbox Parts We Forge
Layshafts & Countershafts
Forged layshafts and countershafts for multi-speed gearbox gear trains.
Output Shaft Forgings
Heavy-duty forged output shafts for torque transmission from gearbox to drivetrain.
Gear Blanks
Near-net forged gear blanks for spur, helical and bevel gearbox gears.
Bearing Sleeve Forgings
Precision forged bearing sleeves and rings for gearbox bearing seat applications.
Custom Gearbox Parts
Any gearbox component forged to OEM drawing and material specification.
Gearbox Forging Materials
20MnCr5 / 16MnCr5
Standard case-hardening steel for automotive and industrial gearbox gear blanks.
42CrMo4 / EN19
Alloy steel for gearbox input, output and intermediate shaft applications.

Precision Gearbox Component Forgings
Shivam Forge is a precision gearbox forging manufacturer in India producing forged input shafts, layshafts, output shafts, gear blanks and bearing sleeves for automotive transmissions, industrial gearboxes and wind turbine drive systems. Our gearbox forgings deliver the fatigue life and case hardenability demanded by high-duty gear applications.
Gearbox shafts and gear blanks operate at high speed under continuous torque loading through millions of gear mesh cycles. The superior grain flow and material density of forged gearbox components provides the fatigue resistance and hardenability essential for long-life gearbox performance compared to machined-from-bar alternatives.
We manufacture gearbox forgings in 20MnCr5, 42CrMo4, 17CrNiMo6 and other alloy steel grades suited for case hardening and through hardening. Near-net forged gear blanks minimize hobbing stock and reduce machining cost, while precision CNC machining of shaft features ensures dimensional accuracy for gearbox assembly.
Shivam Forge supports automotive OEMs, industrial gearbox manufacturers and wind turbine drivetrain suppliers with precision gearbox forging solutions. Our engineering capability, heat treatment expertise and machining infrastructure provide a complete gearbox component forging service from prototype through serial production.
