Key features

Flexible Vibration Damping: Spider elastomer absorbs vibration and buffers impact to protect motors and reduce noise.

Multi-directional Compensation: Compensates for axial (0.5-2mm), radial (0.2-0.6mm), and angular (1-2 degrees) misalignment.

High-Speed Capability: Supports permissible speeds up to 15,000 r/min depending on model and material selection.

Overload Protection: Elastomer deforms or breaks under overload to cut power transmission and protect core equipment.

Customizable Materials: Half-couplings available in stainless steel, aluminum alloy, or carbon steel; elastomers in PU, NBR, or silicone.

Maintenance-Free Design: Keyless/keyway design requires no lubrication, ensuring low daily maintenance costs and easy assembly.

Full Customization Service: Supports custom shaft diameter, keyway, material, elastomer hardness, and surface treatment solutions.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with 3D design, ODM, OEM, and broad customization capabilities. It operates five production lines, uses CNC and testing equipment, has in-stock capacity, and maintains manufacturing contracts with associated subcontractors. Quality and service procedures include product inspection instructions, traceability, complaint handling, and corrective/preventive actions. The supplier reports an ISO9001:2015 certificate and recent fire drills, but lacks a factory environmental impact assessment report. Overseas support is limited: it has no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Financial credibility cannot be fully assessed from the provided year labels alone. Customer cases are not specifically identified, although OEM service for well-known brands is reported.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier, provides 3D software design, maintains manufacturing-capacity contracts with associated subcontractors, and has in-stock service capability. It is therefore positioned as a technical manufacturing and customization supplier rather than only a trading intermediary.

CertificationsAn ISO9001:2015 certificate is reported, providing explicit evidence of a quality-management certification. However, the supplier also reports no factory environmental impact assessment report; this does not negate the stated ISO certification but limits evidence of broader sustainability compliance.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, plus quality assurance and raw-material traceability. However, it has no overseas warehouse, showroom, agents, or branches, so internationally localized after-sales coverage is limited.

R&D capabilityThe supplier reports R&D capability, a new product within the past year, ODM services, OEM services for well-known brands, and 3D software design. It explicitly lacks an available SDK, but the evidence still supports product-development and design capability.

Production capacityProduction capability is supported by five production lines, CNC and other processing equipment, testing instruments, manufacturing contracts with associated subcontractors, inventory capacity, and documented supplier-assessment procedures. Reported lead times are within 15 workdays off-season and one month during peak season.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, alongside 3D design, ODM, and OEM services. These combined offerings indicate broad customization coverage.

Product Q&A

Q:What materials are available for the half-couplings and elastomers?

Half-couplings can be made of stainless steel, aluminum alloy, or 45# carbon steel. Elastomers are available in Polyurethane (PU), Nitrile Butadiene Rubber (NBR), or Silicone.

Q:Can the shaft bore diameter be customized?

Yes, the shaft bore diameter is fully customizable according to national standards or specific customer requirements.

Q:What is the maximum permissible speed for this coupling?

The permissible speed can reach up to 15,000 r/min, depending on the specific model and material selected.

Q:How does the coupling handle misalignment?

It compensates for axial misalignment (0.5-2mm), radial misalignment (0.2-0.6mm), and angular misalignment (1-2 degrees).

Q:Is lubrication required for maintenance?

No, the design is lubrication-free and maintenance-free, requiring no regular lubrication and reducing operational costs.
