Import Drive Sprocket Rim 404-7 — Buy in Bulk from Supplier in China

The Drive sprocket rim 404-7 is a precision‑engineered component intended for machinery that requires a 404‑7 tooth configuration. Produced by Wenzhou Chaohong Machinery Co., Ltd in Zhejiang Province, China, the rim also accommodates 3/8‑7 and 3/8‑8 sizes, offering flexibility across different equipment families. Its construction uses a robust steel alloy designed to endure repetitive stress and wear in demanding environments. The rim’s geometry ensures efficient power transfer with minimal chain slip.

Industry practice typically calls for heat‑treated alloy steel, often corresponding to a standard grade such as ASTM A29, delivering a typical hardness of 56‑61 HRC after quenching and tempering. The tooth pitch for a 404‑7 rim is generally 7 teeth per inch, while the rim width is usually around 0.55 inches, giving an approximate weight of 1.3 kg per unit. A surface roughness of Ra 0.8 µm is common to promote smooth chain engagement. These typical parameters help maintain reliability in continuous‑operation settings.

The rim finds extensive use in agricultural machinery, conveyor systems, and logistics equipment where durable chain drives are critical. Procurement officers in farming cooperatives and material‑handling firms often source this part in bulk, taking advantage of the supplier’s FOB and L/C shipping options. Because the listing does not specify a minimum order quantity, buyers should confirm the MOQ and expected lead time directly with the supplier. Export‑quality documentation can be obtained on request to satisfy import compliance requirements.
