When your custoemr's combine hits a tough patch at full load, that final drive coupling is what takes the shock—if it shears, you're looking at a field day lost and a service call that eats your margin.
We run these from high-grade cast steel with the internal spur teeth hardened on the surface, and precision rolling method keeps the profile consistent across the batch, so you're not fighting runout issues at ±0.01mm accuracy.

Standard dimensoins are DIA140 by 389mm, but we've done custom lengths for guys retrofitting older harvesters—just send the drawing and we'll quote teh MOQ, usually around 50 units or so depending on the complexity.

Every piece gets a 100% inspection before it ships, and you'll get a COA with the batch—HPLC isn't relevant here, but we do check hardness and dimensional tolerances against the print, and our company can supply the raw materail certs if your QA needs them.

Lead time runs 7 to 45 days, and that's the honest spread—if we have the steel stock, it's closer to two weeks, but for a custom heat treat cycle or plating spec, it'll push toward the longer end, so confirm before you lock in your production schedule.
Payment terms are typically T/T or L/C at sight, and we ship FOB from the port—freight forwarder handles the rest, and we'll provide the packing list and commercial invoice for customs clearance without any fuss.
We don't have a strict MOQ—we can handle custom quantities from single prototypes to full production runs. Just let us know your volume, and we'll quote accordingly.
Yes, we include a copy of our ISO9001:2015 certification with every order. We also offer 100% inspection reports on dimensions and hardness if needed.
Lead time for the SPLINE002 ranges from 7 to 45 days depending on quantity and surface treatment complexity. For 50 units, expect around 15-20 working days.
The internal spur gear is precision rolled, not cut, which gives it better fatigue strength. We hold accuracy to ±0.01mm on all critical dimensions.
Absolutely, we offer full OEM/ODM customization—we can adjust length, diameter, tooth profile, or even switch to a different cast steel grade. Just send your specs.
