Gear & Gearbox Design, Engineering and Manufacturing
From gear design to manufacturing-ready transmission systems.
From individual replacement gears and gearbox redesign to new industrial transmission systems, we design, analyse, and manufacture gears and gearboxes for torque, speed reduction, load capacity, reliability, and maintainability, with design, manufacturing, inspection, and testing under one roof.
Design & engineering
Gear design
- Spur, helical, bevel, and worm gears
- Gear trains and multistage ratios
- Heavy-duty, high-torque gears
- Tooth geometry: module, pressure angle, helix angle, centre distance
- Tooth bending and contact strength
- Existing gear redesign
Gearbox design
- Industrial gearboxes and speed reducers
- Multistage and planetary gearboxes
- Shaft and bearing design
- Housing and casing design
- Lubrication and thermal considerations
- Assembly, alignment, and serviceability
Calculations & validation
- Ratio, speed, torque, and power calculations
- Shaft strength and deflection
- Bearing selection and life
- Housing FEA
- Thermal and loss estimates
- Gear-mesh vibration and dynamic loads
Manufacturing
- CNC gear cutting: hobbing and shaping
- Gear finishing: grinding, shaving, honing
- Shaft, housing, and component machining
- Heat treatment
- Precision assembly: backlash, contact pattern, fits
- Inspection, hardness checks, and quality documentation
Industries & applications
- Steel plants: rolling mills, conveyors, and heavy drives
- Cement & mining: crushers, mills, and conveyors
- Material handling: hoists, cranes, and conveyor drives
- Power & process industries: industrial drives and process machinery
- Automotive & general engineering transmissions
- Heavy machinery and industrial equipment OEMs

Frequently asked questions
Can you make a replacement gear without the original drawing?
Yes. We measure the existing gear or gearbox, re-create the geometry and drawings, check the strength for the duty, and manufacture the replacement.
Do you handle the gearbox from design through manufacturing?
Yes. Gear calculations, CAD design, manufacturing, heat treatment, assembly, inspection, and testing are handled as one integrated project.
