Pinion Gear Shaft with Stepped Two-Stage Pinion Gear and Straight-Cut External Teeth

Tooth count ratio between the two gear stages and the shaft step diameter separating them are the primary control callouts for a stepped two-stage pinion gear; the ratio sets the output speed at each stage, while the step diameter determines axial clearance between the two gear meshes in the housing. Ningbo Bhin Precise Machinery (established 2009, Ningbo, Zhejiang) forms this tool steel stepped two-stage pinion gear shaft with straight-cut external teeth using gear forming and CNC turning, with tooth profile on both stages, step diameter, and shaft OD held to your released dimensions tolerances. IATF16949 and ISO 9001 certification at Bhin's Ningbo facility (just over 4,000 m²) governs process documentation for automotive gearboxes, power tools, and robotics two-stage drive applications. PVD surface treatment is available for pinion gear tooth flank hardness, supporting aerospace, medical equipment, and oil & gas projects. Supply your drawing detailing module, tooth counts per stage, step diameter, and tool steel grade — we will provide a gear forming detailed proposal from our Ningbo team.
