What industries can this coupling be applied to?

It is widely used in servo motors, stepper motors, reducers, pumps, fans, CNC machine tools, automation equipment, and general machinery.

Does the coupling require regular maintenance?

No, the design is lubrication-free and maintenance-free, which reduces equipment operation and maintenance costs.

What is the overload protection mechanism?

Under overload conditions, the elastomer can deform or even break, cutting off power transmission to protect core equipment from damage.

Are samples available for testing before bulk orders?

Yes, free samples are provided for standard parts, while charged samples are available for custom complex parts (fee deductible from bulk order).

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-coupling and elastomer?

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

Q:Can the shaft bore diameter be customized?

Yes, the shaft bore diameter is customizable from 6mm to 45mm to accommodate different models and 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 used.

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 the product suitable for high-vibration environments?

Yes, the spider-shaped elastomer effectively absorbs vibration and buffers impact, protecting motors and transmission equipment while reducing noise.
