Import 75 Reducer — Buy in Bulk from Supplier in China

The 75 reducer is an involute cylindrical gear reducer built for heavy-duty mechanical power transmission, converting high input speed into lower output speed with increased torque. Shandong China Coal Industry & Mining Group Co., Ltd. manufactures this unit for integration into mining machinery, conveyor systems, and general industrial equipment where reliable speed reduction is critical. The source data does not specify exact ratio, shaft diameter, or mounting configuration, so buyers should request the ratio range (typical for this series: 5:1 to 20:1), input and output shaft dimensions, and foot or flange mounting options before finalising specifications.

Gear reducers in this class typically employ case-hardened alloy steel gears with involute tooth profiles ground to AGMA or DIN standards for smooth meshing and load distribution. Lubrication is usually achieved through splash or forced-circulation systems with ISO VG220 or VG320 gear oil, depending on operating temperature and duty cycle. Sealing arrangements commonly include double-lip oil seals on input and output shafts to prevent ingress of dust and moisture in mining environments. Housing construction is typically cast iron or welded steel, designed to withstand the shock loads and vibration inherent in coal and mineral processing applications.

Primary buyers include mining equipment OEMs, bulk materials handling contractors, and maintenance departments for cement and aggregate processing plants. The 75 reducer serves as a direct replacement or new-installation component in conveyor drives, crusher feeders, and hoist mechanisms. Trade terms, MOQ, and lead time are not stated in the available data; importers should confirm FOB Qingdao or CIF destination terms, minimum order volume, and whether custom ratio or shaft modifications are supported. Given the supplier's 0.00% response rate and harbour trust tier, buyers are advised to initiate contact well ahead of procurement deadlines and verify current production capacity.

Shandong China Coal Industry & Mining Group Co., Ltd. is headquartered at No.69 Huoju Road in Jining's New & High Zone, Shandong Province, China. The supplier holds an imported tier designation and harbour trust level, with a recorded response rate of 0.00% and zero average response hours in the platform data. This profile indicates limited active engagement signals, so buyers should treat initial outreach as exploratory and allow extended time for quotation and sample requests. The company name and address suggest positioning within China's coal and mining equipment supply chain, though the available data does not confirm specific manufacturing certifications, factory audits, or export licence details.

The listing presents the 75 reducer as an industrial gear unit for heavy-duty applications, but does not disclose production capacity, in-house testing capabilities, or aftermarket parts availability. Buyers should verify whether Shandong China Coal Industry & Mining Group Co., Ltd. manufactures reducers directly or sources from a partnered factory, as this affects warranty terms and technical support. No information is provided on export experience, reference installations, or language capabilities of the sales team. Due diligence on company registration, bank references, and third-party factory verification is recommended before committing to bulk orders.
