Our Custom Metal Super Gear achieves ISO 5 accuracy (GB 5/DIN 5 equivalent) for precision transmission.engineered for non-standard applications that demand exceptional performance. Leveraging Japanese Fuji KPS30 gear shaving machines and Ningjiang YK3610IV CNC hobbing machines, we ensure inner/outer diameter and thickness tolerances within ±0.01mm-ideal for high-precision mechanical systems in automation, aerospace, and medical equipment. Highlight Features ISO 5 level precision Total accumulated deviation of tooth pitch Fp≤0.012mm, total deviation of tooth profile Fa≤0.006mm, reaching ISO 5/GB 5/DIN 5 level standard. ±0.01mm Tolerance control ID / OD / Thickness full size tolerance ≤ ±0.01mm, using the "scraping finishing + precision turning + CMM compensation" process chain. Non-standard customization Module M1~M8 (support M0.3 micro-precision gears), unlimited number of teeth, pressure angle 20°±1° adjustable. Special tooth shapes (trimmed teeth/drum teeth), shaft holes, keyways and other non-standard structures can be customized according to the drawings provided by you. Diversified materials and processes Material matrix: S45C, 304 stainless steel, aluminum alloy, copper alloy, nylon 66, etc. (support for customer-specified materials). Heat treatment: tempering, high-frequency quenching, nitriding (hard-scraping process adapted to the HRC50 + material).
