How is the link installed and secured?

The open end slides onto the mating lug, aligns with holes, and is secured with a hardened steel pin or bolt, often with a cotter pin, lock nut, or retaining ring.

What is your MOQ (Minimum Order Quantity)?

Standard Links: 100 pieces. Custom/OEM Links: 500 pieces. Pins & Hardware: 1,000 pieces. Samples are available for testing.

What is the production lead time?

Samples: 15-20 working days. Standard Production: 30-40 working days. Custom Forging (New Die): 50-60 working days after die design approval.

Can you provide matching pins and hardware?

Yes, we supply complete connection kits including forged horseshoe links, hardened & ground pins, retaining rings, cotter pins, lock nuts, and special washers or bushings.

Do you offer re-forging or re-manufacturing of worn links?

For certain high-value, large-sized links, we offer re-forging and re-hardening services if the core material is sound, subject to photo evaluation.

AI-Powered supplier vetting

SummaryWeifang Shengao Machinery Co., Ltd. is a limited company focused on mechanical parts, hardware, metal tools, CNC machine tools, and related components. It identifies as a professional technical supplier and offers 3D software design and broad customization services, including sample-, design-, full-, minor-, and flexible customization. The supplier has written procedures and records for service assessment, corrective actions, and complaint handling. Its export sales share is stated at 71%–90%, with three years of export experience. However, the supplier has nine employees, only two years of total R&D engineer experience, no new products in the past year, no ODM, SDK, or overseas service infrastructure, and no stated customer cases. Audit information is provided for a TUV Rheinland audit with a validity period from September 4, 2025 to September 3, 2026, but the evaluation result is recorded as 0 and no certification name is specified.

Supplier typeThe supplier explicitly identifies as a professional technical supplier and a limited company. Its stated business and product scope covers mechanical parts, hardware products, metal tools, CNC machine tools, functional components, forgings, and powder metallurgy products; the audit record identifies mechanical parts as the primary product.

After-Sales capabilityThe supplier has clear written procedures and followed records for corrective and preventive actions and for handling customer complaints. This directly supports an established service-response process, although the slices do not provide service performance results or response-time data.

Production capacityThe supplier reports an annual production output range, six to ten quality-control staff, on-time delivery, random production quality inspection, and its own factory. It has nine total employees, so the available evidence supports an operating production capability, while capacity beyond the stated output range cannot be determined.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also welcomes OEM and ODM requests according to its company description. These repeated statements provide direct evidence of broad customization coverage, although the separate record states that ODM is not available, creating a conflict on ODM specifically.

Product Q&A

Q:What is a Mining Connecting Ring (Horseshoe Link)?

A critical forged steel coupling component used in heavy-duty mining chains to connect teeth or adapters on a cutter head to the main drive chain, featuring an open 'U' shape for efficient connection under high-tension.

Q:What materials and forging process are used?

We use high-alloy, through-hardening forging steel (e.g., 42CrMo, 34CrNiMo6) processed via hot die forging and quenched and tempered to achieve high hardness and core toughness.

Q:What are the primary applications in mining?

Essential for chain saw/cutter systems, continuous miners, bucket-ladder dredge excavators, heavy-duty conveyor systems, and any high-shock load power transmission chain systems in mining equipment.

Q:How do I identify the correct connecting ring for my system?

Provide the OEM Part Number, detailed dimensions (Inside width A, Inside height B, Material thickness C, Pin hole diameter D), clear photos, and machine make/model.

Q:What is the load capacity (breaking strength)?

Links are rated for extreme duty with Minimum Breaking Load (MBL) and Proof Load specifications. Custom links are engineered to match or exceed the MBL of the connected chain.
