Precision Bevel Gears Custom Made

December 26, 2025
Discover the ultimate in precision engineering with our custom-made straight bevel gears. Designed for demanding applications, these gears feature a 90° working angle and superior durability thanks to advanced heat treatment. The pinion gear undergoes carburization, while the gear itself is induction hardened, ensuring exceptional wear resistance and longevity.

Crafted from high-grade materials like SAE 4340/40CrNiMoA or AISI 4140/42CrMo for the gear, and AISI 8620/20CrNiMo for the pinion, these gears are built to perform. With a module of 11.5 and a 20° pressure angle, they offer smooth, efficient power transmission. Accuracy is guaranteed with an ISO 8-9 Grade rating, and teeth grinding is included for optimal performance.

Whether you need a standard solution or a completely custom-made gear profile (Gleason type), we can meet your exact specifications. Our manufacturing process utilizes gear shaping for precision and reliability. Explore the steel code grade comparisons to see how our materials align with international standards.
