Hypoid Gear Set

A hypoid gear set is a matched pair — one ring gear and one pinion — whose axes do not intersect, enabling power transmission between non-parallel, non-coplanar shafts. For hypoid gear sets, we provide full-process cutting services: engineering drawing review, high-precision blank preparation, gear cutting, case-hardened grinding (achieving ISO 5 accuracy upon request), and 100% matching set inspection.

Distortion and hardness are measured on incoming inspection before the
