Flange Pinion

YYC Flange Pinion Series

The YYC Flange Pinion Series is designed for direct mounting and easy alignment with gearboxes / reducers, providing precise torque transmission and long-term stability. Each flange pinion is manufactured with high concentricity and optimized tooth contact, ensuring smooth and accurate engagement with YYC racks.

• Module range: M2 – M5
• Tooth profile: Helical, Left Hand Angle 19˚31’42”
• Mounting type: Integrated flange with bolt circle
• Accuracy grade: DIN 6
• Material options: Alloy steel (SCM440)
• Heat treatment: Induction hardened

YYC flange pinions are ideal for applications that require rigid coupling, compact installation, and precise positioning. With advanced grinding and hardening processes, YYC ensures excellent runout accuracy, high load capacity, and extended durability.
