Transmission Components FAQ
What transmission components can you manufacture?
We manufacture gear sets and shafts, synchroniser hubs, bearing housings, shift forks and rails, clutch components, and custom transmission hardware. Our expertise covers manual, automatic, and CVT transmissions.
What materials are best for high-torque transmissions?
Steel 4140 and 4340 are the primary materials for gears and shafts in high-torque applications. 8620 steel is used for carburised and hardened gears. Stainless steel 316 is used for corrosion-resistant components. Aluminium 6061-T6 is suitable for light-duty housings.
What tolerances can you hold on gear teeth?
We hold gear tooth tolerances to AGMA Grade 9-10 (commercial quality). Precision gear manufacturing can achieve AGMA Grade 7-8 (precision quality). Pitch diameter, runout, and profile are verified by gear inspection equipment.
What is the typical lead time for transmission components?
Simple shafts and hubs: 2–3 weeks. Gear sets: 3–4 weeks. Complex assemblies: 4–6 weeks. Lead times depend on material, heat treatment, and gear cutting complexity.
Can you manufacture custom gear ratios?
Yes. We design and manufacture custom gear ratios to your specifications. Module, pitch, tooth count, and pressure angle can all be tailored. CAM programming ensures consistent tooth profiles.
Do you offer heat treatment for transmission gears?
Yes. Heat treatment services include carburising, hardening, tempering, and nitriding. These increase wear resistance and fatigue strength. Heat treat is quoted separately through our treatment partners.
