Our Straight Bevel Gears are precision-manufactured from high-quality alloy steel for demanding right-angle power transmission applications.
Designed to transmit rotational power between intersecting shafts, straight bevel gears provide a robust and cost-effective solution for gearboxes, reducers, drive systems, industrial machinery, and heavy-duty mechanical equipment.
Through controlled machining, heat treatment, and dimensional inspection, our gears are engineered to provide accurate tooth engagement, reliable torque transmission, high wear resistance, and consistent operating performance.
We support OEM and custom straight bevel gear manufacturing according to customer drawings, samples, specifications, and application requirements.
Precision-controlled tooth geometry helps ensure accurate meshing between the mating gear and pinion, contributing to stable power transmission and reduced uneven tooth loading.
Selected alloy steels provide a combination of strength, toughness, fatigue resistance, and machinability suitable for demanding mechanical transmission applications.
Material grades can be selected according to gear size, transmitted torque, operating speed, load conditions, and required service life.
Depending on the application, heat-treatment processes such as carburizing and quenching, induction hardening, or through hardening can be applied to improve surface hardness, wear resistance, and load-carrying capability.
The robust gear structure is suitable for applications requiring reliable torque transmission under continuous or intermittent heavy loads.
Straight bevel gears are designed for power transmission between intersecting shafts, commonly at a 90° shaft angle, depending on the gearbox or mechanical system design.

Common material options may include:
20CrMnTi
20MnCr5
AISI 8620
18CrNiMo7-6
Other equivalent grades according to customer requirements
For demanding transmission applications, carburizing and quenching can be used to produce a hard, wear-resistant tooth surface while maintaining a relatively tough core.
Other heat-treatment processes may be selected depending on gear dimensions, material, load requirements, and design specifications.
Straight bevel gears require accurate control of tooth geometry and dimensional tolerances to achieve reliable gear meshing.
