Import 25mm Stainless Steel Wire Rope Nylon Pulley — Buy in wholesale FOB from Supplier in China

The ZB6607-25 is a compact 25mm stainless steel wire rope pulley built around a nylon sheave, measuring 45mm in overall length, 26mm in width, and 11mm in thickness with a unit weight of 23g. The body is cast from AISI 316 stainless steel through investment casting, with a polished surface finish, and the pulley is designed for attachment to line or wire in marine and lifting applications. This grade of stainless steel offers superior resistance to chloride corrosion compared to 304, making it suitable for sustained saltwater exposure.

316 stainless steel contains 2-3% molybdenum by composition, which provides enhanced pitting and crevice corrosion resistance in marine atmospheres. The investment casting process used by Wudi Zhibo Metals allows for near-net-shape production of complex rigging geometries, followed by in-house machining and polishing. The nylon sheave material reduces friction against synthetic ropes and prevents galvanic corrosion when paired with aluminium or carbon fibre components. Standard packaging is an individual OPP bag with outer carton, with a minimum order quantity of one piece.

Typical buyers include sailboat riggers, canoe outfitters, marine chandlers, and industrial lifting equipment distributors. The pulley suits static and low-speed running rigging where weight and corrosion resistance outweigh load capacity requirements. Buyers should confirm the working load limit and breaking strength with the supplier, as these are not stated in the source data. Shackle compatibility, rope diameter range, and whether the sheave is bushed or bearing-mounted should also be verified before specification.

Wudi Zhibo Metals Co., Ltd. operates from No.161 Delixi Industrial Zone in Binzhou, Shandong Province, China, and maintains an integrated manufacturing setup comprising an investment castings foundry and a machining shop. The company produces rigging hardware, marine hardware, and custom cast parts from stainless steel 304 and 316, with polishing and finishing carried out in-house. Their stated product range includes anchors, hinges, deck fillers, fishing rod holders, eye plates, eye bolts, shackles, turnbuckles, thimbles, carabiners, cleats, latches, bollards, and stanchions.

The supplier holds a harbor trust tier and shows a 0.00% response rate with zero average response hours in the available data, which suggests either a new listing or unrecorded communication metrics. The company emphasises its factory status and capability to produce from customer samples or drawings. Buyers should verify current production capacity, quality management system certification, and export experience directly, as no ISO, CE, or other certificates are mentioned in the source material. The brand names associated with this product include Richwits and Zhibo.
