These are precision-engineered 42CrMo4 forged rings, CNC-turned blanks designed for automotive gear wheel applications. The alloy steel grade 42CrMo4, equivalent to AISI 4140, meets EN 10083 standards and delivers superior tensile strength and wear resistance for power transmission systems. Supplied as bearing inner and outer rings, they are heat-treated and optionally pre-machined to reduce downstream processing costs for buyers.
The material composition ensures consistent mechanical properties, with chromium and molybdenum enhancing hardenability and toughness. Typical industry grades for such rings include a carbon content of 0.38 to 0.45%, silicon 0.17 to 0.37%, and manganese 0.60 to 0.90%, with phosphorus and sulfur limited to 0.025% each. Surface finish and dimensional tolerances are held to machining standards typical for automotive components, ensuring compatibility with gear assemblies.
Common buyers include automotive OEMs and tier-1 suppliers manufacturing gearboxes, drive shafts, and clutch assemblies for commercial and passenger vehicles. The rings are exported globally with flexible MOQs, and buyers should confirm Incoterms such as CFR or CIF for bulk shipments. Packaging is typically in wooden crates or steel pallets to prevent deformation during transit.

Before ordering, verify the mill test certificates for chemical composition and mechanical properties to ensure the material meets your specifications. Request documentation for traceability, including heat numbers and batch details, as these are critical for quality control in automotive applications. Confirm whether the rings are supplied in the as-forged, heat-treated, or pre-machined condition.
Logistics details such as lead time, Incoterms (e.g., CFR or CIF), and packaging requirements should be clarified upfront. Lead times for forged rings can vary based on diameter, quantity, and additional machining needs, so plan accordingly. Port of loading will typically be a major Chinese port such as Shanghai or Ningbo, but confirm this with the supplier to align with your shipping arrangements.
Inspect the rings upon arrival for dimensional accuracy, surface finish, and absence of defects like cracks or inclusions. Use calibrated gauges to check tolerances and request a third-party inspection if your contract includes such provisions. Ensure the supplier provides all necessary documentation, including material certificates, heat treatment records, and ultrasonic test reports where applicable.
