Roller machinery metal parts are precision‑engineered components supplied for use in steel mills, paper mills, printing presses and conveyor systems. The parts are manufactured from alloy steel 4140 or carbon steel C45, both of which are widely accepted for high‑stress industrial applications. The supplier notes that hardness values range from 45 to 60 HRC, providing the durability required for continuous operation under load.
In the metal‑working industry, a hardness of 45‑60 HRC is standard for bearing‑type parts that must resist wear while maintaining dimensional stability. Surface finishes are typically milled to a Ra of about 0.8 µm, and dimensions are customised per client drawing, with typical diameters between 50 mm and 200 mm and lengths from 100 mm to 400 mm. These specifications align with common OEM requirements for roller‑driven machinery.
The parts are bought by plant maintenance teams, OEM manufacturers and equipment service providers that need reliable replacement components. Shipments are usually packed in wooden crates or on pallets with a rust‑preventive coating, and the supplier offers FOB or CIF terms with payment by L/C or T/T. MOQ is described as flexible, so exact quantities should be confirmed with the exporter before ordering.

The firm supplies industrial‑grade metal parts and highlights OEM‑quality production since 1998, offering a range of sizes and surface finishes that can be customised to client specifications. While the listing confirms the use of alloy and carbon steels and mentions standard industry certifications, it does not disclose production capacity, client list or detailed quality‑system certifications beyond the generic ISO/SGS reference.
Roller machinery metal parts are essential components used across steel mills, paper mills, printing presses, and conveyor systems. These precision-engineered components are typically manufactured from high-grade carbon steel or alloy steel such as 4140 and 4340, with hardness ratings ranging from 45 to 60 HRC for durability under high stress. Widely traded internationally for maintenance, repair, and OEM applications, these parts are exported in wooden crating or pallets with rust preventive coating to ensure integrity during shipping. Specifications such as diameter, length, and surface finish are customized to client requirements and operating conditions.

Confirm the steel grade, hardness range and surface‑finish tolerance with the supplier before finalising the purchase. Request detailed dimensional drawings and verify that the rust‑preventive coating on the packaging meets your handling and storage standards, especially if the parts will be stored outdoors before installation.
Because the components are heavy and may be shipped in bulk, arrange freight forwarding that can handle wooden crates or palletised loads. The supplier offers FOB or CIF options; ask for an estimated lead time and agree on payment terms - typically L/C or T/T - before confirming the contract. Ensure that all customs documentation, such as the commercial invoice and packing list, is prepared in advance.
Schedule an independent inspection either at the factory or upon arrival to check hardness, dimensional accuracy and surface finish. Obtain the ISO/SGS test reports and any material certificates to satisfy your quality assurance requirements, and keep all inspection records for customs clearance and future warranty claims.
