Roll testing optimizes the tooth contact area, ensuring uniform load distribution.
A miter gear is a unique bevel gear variant where two identical gears mesh at right angles. This setup offers direct 1:1 speed redirection, but places heavy thrust loads on the bearing assemblies. Here is how our engineering team optimizes miter sets for smooth performance:
Miter gears are designed exclusively for angular direction changes without affecting torque or output speeds. Because both gears share identical dimensions, we cut their teeth concurrently on multi-axis CNC generators to prevent minor rotational lag or indexing errors.
Get Instant QuoteUnlike cylindrical gears, miter gears generate dual-axial thrust forces that push the gears apart. By modifying the back cone angles and optimizing tooth crown curvatures, our designs direct these axial forces squarely into your shaft bearings, preventing gear binding.
Get Instant QuoteTo ensure high-speed performance without binding, we control tooth thickness allowances to strict microns. We help you define your mounting distance boundaries, allowing quick assembly adjustments while keeping backlash minimal.

Our engineering team reviews all drawings for manufacturability and can suggest modifications to improve quality, reduce cost, or shorten lead time—at no additional charge.
Send Your DrawingWenlio Gear maintains a reliable, straightforward timeline to guarantee absolute conformity from raw alloy forging blanks down to physical delivery.
Our team performs a complete Design for Manufacturability (DFM) review of your 2D and 3D CAD files.
Once approved, we forge raw gear blanks from certified structural steel alloy bars, matching metallurgical grain flow with expected operational thrust loads.
Pre-machining on heavy-duty CNC turning stations sets precise locating datums.
This step ensures key blank surfaces—such as back cone dimensions, back planes, and bores—are concentric to runout tolerances below 15 microns.
We cut miter teeth profiles on specialized bevel gear hobbers or shaping centers.
The cut gears then undergo controlled atmosphere carburizing and press-quenching, achieving a hard wear-resistant outer crust (HRC 58-62) with a resilient, ductile core.
Following heat treatment, teeth surfaces are ground to remove any thermal distortion.
Every batch then undergoes dynamic rolling tests with its companion gear on our Gleason testers to verify quiet operation and proper backlash before shipping.
Get answers to the most common questions we receive from engineering and procurement teams. Can’t find what you’re looking for? Contact us directly for project-specific guidance.
A: Yes. While standard miter gears intersect at exactly 90° with a 1:1 ratio, we can customize the shaft angle (e.g., 60°, 120°) to match your exact gearbox housing prints.
A: Because miter gears have a 1:1 ratio, they share identical wear patterns. Replacing only one gear causes rapid tooth fatigue, high backlash, and vibration. We always supply them as lapped, matched pairs.
A: We achieve up to AGMA Class 14 (ISO 5) using state-of-the-art CNC profile grinding machines, which minimizes operational noise and heat generation in high-speed applications.
A: We recommend 20CrMnTi or 18CrNiMo7-6 with case-carburizing. This creates a hard wear-resistant outer crust (HRC 58-62) while keeping the core ductile to absorb sudden torque spikes.
A: Absolutely. Protecting your intellectual property is our priority. We routinely sign standard B2B NDAs before our engineering team reviews your STEP, DWG, or PDF drawings.
