SX-109 is the model we settled on, and teh hardened tooth surface is what actually makes it worthwhile for high-wear setups like marine drives or those constant-load toy motors.
It's stainles steel, so you're getting decent corrosion resistance without going to a specialty alloy, and the hardening process on the teeth means the contact faces won't deform as fast as a standard untreated part—usually we see a 20-30% longer service interval in our test runs.
We ordered it with a custom bore and keyway because our sprocket pitch was slightly off from the standard spec, and the suppiler can handle that without a massive upcharge (lead time is roughly 10-12 days for the first piece).
Most buyers go with standard package unless they need a specific coating or a particular laser marking, but for our marine application we had them add a passivation step, which isn't standard but they do it for a small fee.
Also, it's not suited for ultra-high-torque chain drives like in heavy mining equipement—the stainless alloy lacks the impact toughness of through-hardened steel for that, but for electric cars and agricultural machinery it's pretty much fine.
The MOQ was 10 units for the custom run, and they provided a COA with each batch showing hardness and chemical composition, which saved us from having to verify in-house later.
For custom SX-109 sprockets, our MOQ is typically 100 pieces. But if you're running a small test or prototype, we can sometimes work with lower quantities—just reach out and we'll see what we can do.
Lead time for custom SX-109 sprockets is usually 15-20 working days after design approval. Standard models can ship within 7-10 days. Exact timing depends on the complexity of your customization.
Yes, we can provide a mill test certificate for the stainless steel and a hardening report for the tooth surface. Just let us know when you place the order, and we'll include it in the shipment.
Absolutely. We offer OEM/ODM customization, so we can laser engrave your logo, part number, or any marking you need right onto the sprocket body. Just send us the design file.
We offer both standard packaging (individual poly bags in cartons) and custom packaging like blister packs or wooden crates for marine-grade protection. Just specify your preference when ordering.
