Bevel Gear Overview

Straight Bevel, Spiral Bevel, Miter, Zerol, Anti-Backlash Gears & More Bevel gears are essential for smooth, low-noise power transmission between non-parallel shafts at virtually any angle or speed. Their unique geometry enables efficient torque transfer in a wide range of automotive, industrial, and power transmission applications. Due to the complexity of their design and precision requirements, manufacturing high-quality bevel gears demands advanced engineering and specialized processes.
At AmTech International, every bevel gear project starts with the right raw material—whether forged, bar stock, or castings—chosen based on the required strength and performance. Forged blanks are preferred for applications demanding superior strength-to-weight ratios and enhanced impact and fatigue resistance.
Our manufacturing process includes precision machining operations such as turning, grinding, and specialized finishing to achieve tight tolerances and optimal tooth geometry. The final gear cutting and hard finishing stages ensure maximum tooth contact, durability, and performance. Each gear undergoes thorough inspection, including dimensional checks and advanced testing methods like magnaflux, to guarantee quality and reliability.
AmTech’s bevel gear manufacturing services deliver high-precision gears designed to maximize efficiency and longevity in powertrain and power transmission systems. We offer expertise in both spiral and straight bevel gears, as well as specialty types like miter, zerol, and anti-backlash gears.

Spiral Bevel Gear Capabilities

Spiral bevel gears are engineered to transmit power between shafts at a 90-degree orientation. Their curved, oblique teeth provide smoother, quieter operation and greater load capacity compared to straight bevel gears. The unique tooth geometry reduces sliding, resulting in lower operating temperatures and improved efficiency—making spiral bevel gears ideal for high-speed, high-torque applications.
  • Module Range: M2 to M15
  • Maximum Outer Diameter: 600 mm

Zerol Bevel Gears

Zerol bevel gears are a variation of spiral bevels, featuring a spiral angle of zero. They combine the gradual tooth curve of spiral bevels with the operational characteristics of straight bevel gears, offering precise motion and tight tolerances for specialized gearboxes and machinery.
