Spur Gears
Custom gears transmit torque and rotational motion across mechanical drives, and NOWARUN manufactures them to customer drawings from module 0.5 to module 10. Gears are produced to precision levels from DIN 5 to DIN 10 across carbon steel, alloy steel, stainless steel, and polymer grades. Cutting processes include hobbing, shaping, shaving, and grinding to match the target accuracy, followed by specified heat and surface treatments.

- Corrosion and surface degradation in harsh industrial environments solved by targeted treatments like Geomet, Dacromet, or plating
- Gearbox vibration and tooth engagement noise resulting from inadequate tooth finishing methods
Who It Is For
- Procurement engineers sourcing custom gears machined strictly to internal drawing tolerances
- Equipment designers specifying tailored gear geometries across carbon steel, alloy steel, or polymer
- Machinery maintenance departments requiring replacement gears made to drawing rather than standard stock
- Contract manufacturing managers seeking verified heat treatment and tooth finishing on custom gear orders
Application Scenarios

- Surface finishes including plating, E-coating, Geomet, Dacromet, Delta, brushing, polishing, and oiling
- Traceable identification via laser engraving directly on the gear body
Materials
- Carbon steel for general duty gearing requiring balanced machinability and strength
- Alloy steel for gears requiring carburizing or induction hardening to handle heavy torque

- Custom metal grades sourced to match specific international national standards
How It Is Made
- 1
Engineering review of the customer drawing, module, tooth geometry, and specified DIN grade
- 2
Turning the blank to final outer diameter, bore, and face width dimensions
- 3
Tooth generation utilizing hobbing, shaping, or milling processes
- 4
Heat treatment via carburizing, carbonitriding, QT, quenching, tempering, or induction hardening
- 5
Tooth finishing by shaving or grinding to achieve the specified DIN 5 to DIN 10 precision
- 6
Application of surface treatments like plating, E-coating, Dacromet, Geomet, or protective oiling
- 7
Final inspection, laser engraving if specified, and protective packaging into bags, cartons, or crates
Quality Control
- Verification of tooth profile, lead, and pitch accuracy against the designated DIN 5 to DIN 10 grade
- Dimensional measurement of bores, keyways, face widths, and mounting locations
- Hardness and case depth verification following carburizing, carbonitriding, or induction hardening
- Visual inspection of surface finishes, including plating, coating thickness, and laser engraving clarity
Customization Options
- Custom gear cutting fully made to customer print rather than off-the-shelf sizes
- Bore configurations, keyways, splines, and mounting holes machined to match customer shafting
- Selection of tooth generation methods from hobbing to grinding depending on precision needs
- Choice of surface coatings from rust-preventative oiling to Geomet, Dacromet, or plating
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Ground gear teeth | Tooth grinding reaches higher precision such as DIN 5 but requires additional machine time compared to hobbing or shaving |
| Standard catalog gears | Catalog gears ship immediately but require secondary machining on bores and hubs to match custom equipment |
| As-machined unhardened gears | Unhardened gears are faster to produce but wear rapidly under high-load continuous machine operation |
Use Guide
- Provide complete drawing files indicating module, tooth number, pressure angle, and precision grade
- Specify the required DIN precision level between DIN 5 and DIN 10 to establish appropriate grinding processes
- Identify heat treatment parameters including required surface hardness, core toughness, or case depth
- State the operating environment to determine whether oiling, plating, Geomet, or Dacromet is required
- Inspect gear mounting alignment and backlash during installation into the final drive assembly
