The YYC Helical Ground Welded Flange Pinion Series is designed for applications requiring high precision, rigidity, and stable torque transmission. Each pinion is precision-ground and welded to an integrated flange hub, achieving both compact structure and superior alignment accuracy with YYC racks.
• Module range: M2 – M6
• Tooth profile: Helical, Left Hand Angle 19˚31’42”
• Manufacturing process: Precision Ground and Welded.
• Mounting type: Welded flange with bolt circle
• Accuracy grade: DIN 6
• Material options: Alloy steel (SCM415)
• Heat treatment: Carburized on pinion, Flange is soft.
YYC welded flange pinions are ideal for where vibration resistance and torque accuracy are critical. The precision-ground tooth surface ensures low noise, smooth operation, and consistent backlash performance, even under heavy load or continuous motion.
