Stepped Carbon Steel Shaft With Splined Gear Shaft and Axial Hole

Batch supply for splined gear shaft to maintain stable geometry across batches. Our production plant in Huaian holds IATF 16949 and ISO 9001 and supports gear forming and precision machining. We stabilize batch-to-batch dimensions and fit features under your approved manufacturing data. For this release we lock in your specified major diameter, critical tolerance window, and surface finish as controlled parameters on the splined gear shaft. For release control you can send a released CAD file in neutral STEP or Parasolid, or provide a detailed drawing. If you need prototypes, we can run a small batch for the Batch supply to validate form and fit before a larger order. For the part described, standard batch pricing applies based on quantity, inspection scope, and any special surface-finish checkpoints in your release.
