Elastic Single And Double Diaphragm Coupling
The elastic single and double diaphragm coupling from Hebei Rongxing is designed for precise torque transmission between coaxial shafts in automotive and industrial drive systems. It compensates for angular and parallel misalignment up to 1.5 degrees and 2 mm offset, with a nominal torque range of 0.4 to 4500 kN·m. The coupling uses high-strength alloy steel or carbon steel with heat treatment, ensuring durability under high torsional loads and continuous operation.
These couplings feature a drum gear tooth profile with precision-machined teeth and a flexible diaphragm stack that absorbs vibration and reduces shock loads. The operating temperature range is -20°C to 80°C, suitable for most industrial environments. Typical diaphragm thicknesses range from 0.8 mm to 2.5 mm depending on torque class, and the surface is treated for corrosion resistance. This design is standard in heavy-duty automotive transmissions and industrial gearboxes where alignment tolerance is critical.
Buyers include OEMs in truck and construction machinery manufacturing, aftermarket distributors in Europe and Southeast Asia, and maintenance suppliers for mining and marine drive systems. Packaging is in wooden crates with internal foam padding, and standard MOQ is 10 units per model. Lead time is typically 15 to 25 days after order confirmation. Incoterms available include FOB Hengshui Port and CIF destination port.

Hebei Rongxing Driving Equipment Technology Co., Ltd. is based in Hengshui City, Hebei Province, China, with a manufacturing facility located in the Southern Industrial New Town. The company specializes in the production of gear couplings, diaphragm couplings, and universal joints for automotive and heavy machinery applications. The listing shows a harbor trust tier, indicating verified business registration and factory inspection, but no response rate or average reply time is provided, suggesting limited buyer engagement on the platform.
The supplier does not claim certifications such as ISO 9001, nor does it list export history, client names, or production capacity. There is no mention of in-house R&D, testing equipment, or quality control protocols beyond the material and torque specifications stated. Buyers should request documentation for material certificates and dimensional inspection reports before placing bulk orders.
Elastic single and double diaphragm couplings are essential mechanical power transmission components widely used in automobile drive shaft systems to connect horizontal coaxial axes while compensating for angular and offset misalignment. The CL drum gear coupling features a robust steel construction designed for high-torque applications in automotive transmissions, offering reliable performance and easy maintenance. These couplings are critical spare parts in the global automotive parts supply chain, with strong demand from OEMs, aftermarket distributors, and industrial drive system manufacturers worldwide.

Sourcing Elastic Single And Double Diaphragm Coupling from Hebei Rongxing Driving Equipment Technology Co., Ltd. - China Import Guide
Before ordering, verify the material certification for the alloy steel or carbon steel used, especially if the coupling will operate under high stress or extreme temperatures. Request dimensional drawings with tolerances for shaft bores and keyways, and confirm the diaphragm stack thickness matches your torque and misalignment requirements. Ensure the supplier provides a traceable batch number for each unit shipped.
Confirm the Incoterms and lead time with the supplier. FOB Hengshui Port is standard, but CIF or DAP may be negotiable for larger orders. Lead time is typically 15 to 25 days after deposit, but this may extend during peak production seasons. Payment terms often require 30% advance with balance against shipping documents. Ask for packaging details to ensure protection against corrosion during sea transit.
Conduct a pre-shipment inspection focusing on surface finish, gear tooth alignment, and diaphragm integrity. Use a micrometer to check bore diameters and a dial indicator to verify concentricity. Request copies of the torque test report and dynamic balance certificate. Ensure the delivery includes a packing list with part numbers, quantities, and material certificates. Retain samples for quality benchmarking in future orders.
