Import Blind Drilled Press Roll — Buy in wholesale FOB from Supplier in China

The Blind Drilled Press Roll supplied by Zhongtian Rubber Roll Manufacturing Co. Ltd. is a heavy-duty component engineered for industrial pressing operations. It is constructed from HT-300 cast iron, a material selected for its high tensile strength and resistance to deformation under load. The roll body features a consistent 120mm thickness, providing structural stability for high-pressure environments in textile, automotive and packaging machinery. Blind drilling in the surface reduces weight while maintaining rigidity, a design choice common in presses where vibration dampening is critical.

Press rolls of this type are typically surfaced with rubber or composite layers to improve grip and wear resistance, though this listing specifies a cast iron base as the core material. Standard industry practice for such rolls includes hardness testing to 60-65 HRC for the working surface, with dynamic balancing to ensure smooth operation at high rotational speeds. The blind holes, usually drilled to a depth of 50-70% of the wall thickness, are spaced according to the load distribution pattern, a parameter often customised per application.

These rolls are primarily used in calendering, laminating and coating lines where uniform pressure is required across a wide web. Buyers in the textile sector use them for fabric finishing, while packaging manufacturers rely on them for film and foil lamination. The rolls are typically supplied as bare castings or with a machined finish ready for rubber coating. Trade terms such as FOB or CIF are common, with packaging adapted to protect the precision-machined surfaces during transit. Confirm the supplier’s ability to provide surface treatment or additional machining if required for your specific process.

Zhongtian Rubber Roll Manufacturing Co. Ltd. is based in Qinyang City, Henan Province, China, with its registered address at No.15 Huaifu Road. The company operates within the Jiaozuo region, a hub for heavy machinery and industrial component manufacturing. Its profile indicates a focus on rubber and cast iron rolls for pressing applications, with a trust tier classification of harbor, reflecting basic verification status.

The supplier’s response signals are currently inactive, with a 0% response rate and no recorded average response time. This suggests buyers should expect to initiate contact proactively and may need to follow up to obtain timely quotes or technical details. The company’s listing does not provide additional information on production capacity, certifications beyond ISO and SGS, or export history, so these details should be confirmed directly with the supplier before placing orders.
