Stepped Spur Gear Shaft Assembly With Two Segments and Thick Central Hub

Alloy steel's fatigue strength and machinability after heat treatment make it the standard choice for this spur gear shaft assembly, where gear teeth and shaft journals must primarytain tolerance under cyclic torque load. SYGO turns the stepped hub and shaft from alloy steel bar stock in Pinghu, with tooth geometry machined and cylindrical-ground to your specified tolerance class. Bore and OD runout are inspected before release using calibrated equipment under SYGO's IATF 16949 and ISO 9001 quality system; dimensional records are kept for each production order. Our in the region of 4,000 m² Zhejiang facility serves bearing and transmission, automotive, robotics, agricultural machinery, and electric motor applications, with 70 staff operating turning, milling, and grinding lines. Send your assembly drawing with tooth module, shaft tolerance class, and material grade to receive pricing, serving aerospace, military, and automation applications.
