These logistical details are crucial for buyers assessing total landed costs and storage requirements, as the packing method can influence protection against corrosion during transit and handling.

Part numbers and model codes serve as the primary identifiers for sourcing, with examples such as WG9925160621, 160200, and Ef750 HINO trucks clutch kits appearing in the market. These identifiers often correlate with specific vehicle makes or machinery types, including cars, motorcycles, farm machinery, tractors, heavy-duty trucks, and racing cars. Buyers should treat these model numbers as observation points rather than universal standards, verifying that the part number matches the exact OEM specification for their application. The presence of multiple model codes for similar dimensions suggests that minor variations in internal design or material treatment may exist, requiring careful cross-referencing with vehicle service manuals.

Technical Specifications to Verify

Technical verification is the most critical phase of sourcing clutch plates, as mismatches in dimensions or operational modes can lead to immediate failure or premature wear. Key specifications to verify include the physical dimensions, such as 1801251921.6 mm or 2101452324.2 mm, which must align precisely with the transmission housing and flywheel interface. Additionally, the working mode, whether it is power combining or electricity combination, and the working state, such as linkage or semi-linkage, must be confirmed against the vehicle’s design. For electromagnetic clutches, the voltage rating (DC12V or DC24V) and stroke type (2 Stroke or 4 Stroke) are non-negotiable parameters that dictate electrical compatibility and engagement behavior.

Material composition and classification are equally important, with products often labeled under ISO/TS16949 standards for friction or hydraulic clutches. The distinction between a clutch disc, clutch cover, and clutch plate is vital, as each component serves a different function in the assembly. Buyers should verify the stroke count and whether the clutch is a dry single plate or a magnetic powder type, as these factors influence heat dissipation and engagement smoothness. Furthermore, the standard weight classifications, such as 10kg, 14kg, or 30kg, may indicate the robustness of the assembly or the packaging weight, requiring clarification to ensure accurate logistics planning and structural integrity expectations.

Compliance and Safety Documentation

Compliance with international standards is a prerequisite for sourcing clutch plates, particularly for applications in regulated markets or heavy-duty industries. Certifications such as ISO/TS16949, CE, E-Mark, and RoHS are commonly cited in product listings, indicating adherence to quality management systems and environmental regulations. Buyers must request valid certification documents to verify that the supplier’s manufacturing processes meet these standards, rather than relying solely on the presence of certification labels on product pages. The classification of the product, such as hydraulic clutch or friction clutch, should be explicitly stated in the certification scope to ensure relevance to the specific component being purchased.

Safety documentation should also include detailed technical data sheets that outline the operational limits and maintenance requirements of the clutch plate. For electromagnetic clutches, electrical safety standards are paramount, and buyers should ensure that the voltage and current specifications are clearly documented to prevent electrical hazards. In the case of heavy-duty truck or racing car applications, the durability and failure modes of the clutch should be addressed in the supplier’s technical literature. Buyers should verify that the supplier provides adequate warranty information and support for compliance-related issues, as non-compliant parts can lead to significant liability and operational downtime.

Cost Drivers and Commercial Terms

Cost drivers for clutch plates include material costs, manufacturing complexity, and packaging requirements, all of which influence the final price and minimum order quantity (MOQ). The observed price range in the market spans from $0.1 to $200, reflecting the diversity from simple friction discs to complex hydraulic or electromagnetic assemblies. MOQs typically range from 1 to 5000 units, allowing for flexibility in procurement strategies, whether for small-scale repairs or large-scale fleet maintenance. Buyers should negotiate terms that balance inventory costs with supply chain reliability, considering the lead times and shipping methods, such as FOB or ocean freight, which can impact the total cost of ownership.

Commercial terms should also address the customization options available, as many suppliers offer tailored solutions for specific vehicle models or machinery types. Customization can affect pricing and lead times, so buyers should clarify the additional costs and time required for bespoke specifications. Packaging options, such as pallets, cartons, or antirust paper, should be included in the commercial agreement to ensure that the products arrive in optimal condition. Buyers should also consider the brand reputation, such as Gpi, as it may influence pricing and perceived quality, but should verify that the brand’s quality control processes align with their own standards.

Supplier Qualification and Quality Control

Supplier qualification is essential to ensure that the clutch plates meet the required quality and performance standards. Buyers should conduct thorough due diligence on potential suppliers, verifying their manufacturing capabilities, quality control processes, and track record in the industry. The presence of certifications like ISO/TS16949 is a positive indicator, but buyers should also assess the supplier’s ability to maintain consistent quality across batches.
