Custom Spiral Bevel Gear Manufacturer & CNC Machining Services
Custom CNC bevel gears are engineered for intersecting or right-angle shaft power transmission, heavily utilized in heavy-duty gearboxes, automotive differentials, and industrial robotics. Utilizing multi-axis CNC machining, precision gear hobbing, and controlled heat treatment, these gears deliver accurate tooth profiles, quiet meshing, and consistent load distribution under harsh torque loads.
Manufacturing Capabilities: Straight bevel gears, spiral bevel gears, and zerol bevel gears.
Production Capacity: Custom production scaling from single rapid prototypes to high-volume production batches (10,000+ units).

Stainless Steels: AISI 304, 17-4PH (for corrosive or cleanroom environments).
Non-Ferrous & Plastics: Aluminum bronze, POM, Nylon (for light-load or low-noise requirements).
Surface Finishes & Heat Treatment
Carburizing & Quenching: Case depth tailored to application load requirements (typically 0.8 mm – 2.0 mm; surface hardness up to 58–62 HRC).
Nitride Treatment: Enhances fatigue strength with minimal dimensional distortion.
Black Oxide / Passivation: Applied for corrosion resistance on carbon and stainless steels.
Shot Peening: Induces compressive residual stress on tooth roots to improve bending fatigue life.
Customization & OEM
File Formats Accepted: STEP, IGES, SolidWorks, and PDF engineering drawings complete with clear GD&T callouts.
