Customized Double Rubber Couplings from Hebei Rongxing Driving Equipment Technology Co., Ltd. are engineered for automobile drivetrain systems, transmitting torque between coaxial shafts while compensating for angular, radial and axial misalignment. The couplings use Natural Rubber (NR) or EPDM compounds bonded to steel flanges, with an operating temperature range of -30 to 150°C and a torque capacity spanning 45 to 800,000 N·m across available models.
These flexible couplings reduce vibration and extend the service life of connected machinery, making them a critical component in commercial vehicles and industrial driveshafts. The snake-spring housing design, paired with rubber elements, absorbs shock loads and accommodates shaft offsets without metal-to-metal contact. Standard industry variants often specify hardness ranges of 50 to 70 Shore A for the rubber, with typical elongation at break exceeding 300% for NR compounds.
Primary buyers include OEMs and aftermarket suppliers in the automotive and heavy machinery sectors, particularly for applications requiring reliable torque transmission under variable loads. The couplings are suited for bulk procurement, with typical packaging in wooden crates or pallets to prevent deformation during transit. Buyers should confirm shaft hole diameters, nominal torque ratings and allowable speed limits for their specific model, as these directly impact compatibility with existing drivetrains.

Before ordering, verify the exact torque capacity, allowable speed, and misalignment tolerances for the selected model, as these must align with your drivetrain’s operational limits. Confirm the shaft hole diameter and length to ensure compatibility with existing equipment, as mismatches can lead to installation issues or premature wear. Request material test certificates for the rubber compounds to validate their mechanical properties.
Discuss logistics terms, including Incoterms such as FOB or CIF, and confirm the port of loading in China, typically a major hub like Tianjin or Shanghai. Lead times may vary based on customisation requirements, so clarify production schedules and any potential delays. Payment terms, such as TT or LC, should be negotiated upfront to avoid discrepancies during transaction processing.
Inspect the couplings upon arrival for dimensional accuracy, material consistency, and absence of defects like cracks or deformations. Request third-party inspection if the order volume justifies it, focusing on critical parameters like torque capacity and rubber hardness. Ensure all documentation, including packing lists, test reports, and compliance certificates, is provided and matches the agreed specifications.
