Import Conveyor Roller — Buy in wholesale FOB from Supplier in China

The SPD conveyor roller supplied by Rizhao Port Shipbuilding & Machinery Industry Co., Ltd. is a steel-based or HDPE roller designed to meet JIS/DIN standards for heavy-industry applications. Available diameters range from 76 mm to 219 mm and lengths from 190 mm up to 3 500 mm, allowing configuration for a wide variety of belt widths between 400 mm and 2 000 mm. Each roller is built around a Q235 carbon-steel pipe with high-precision ERW seam and a cold-drawn bright-round steel shaft, both treated for corrosion resistance. The unit incorporates deep-groove ball bearings with a ZZ C3 shield and a labyrinth seal that is dust-proof and waterproof.

The rollers are offered in colour options such as black, red, blue or yellow and can receive an ordinary paint, rubber coating or galvanised finish according to client request. Bearings may be supplied by SKF, FAG, NSK, LYC or a supplier-specified brand, and the shaft tolerance is tightly controlled to ensure balanced rotation. Typical industry practice for rollers of this size includes a surface hardness of 60-70 Shore A for rubber variants and a dynamic load capacity of up to 10 kN, which matches the performance of many port and cement plant conveyors. Production capacity is listed as 800 pieces per day, and the design life is stated at 30 000-50 000 hours under normal maintenance.

These rollers are commonly used in ports, cement plants, power stations and other bulk-material handling systems where continuous operation and low maintenance are essential. Importers should verify colour, finish, bearing brand and seal type against their system requirements, and request the export-standard plywood case with waterproof film for safe transit. Minimum order quantities, lead times and payment conditions are not disclosed in the listing and should be confirmed directly with the supplier. The supplier’s trust tier is 'harbor' and response metrics are currently unavailable, so clear communication before contract signing is advised.

Rizhao Port Shipbuilding & Machinery Industry Co., Ltd. is located on Shanghaor Road in Rizhao, Shandong Province, China (postal code 276826). The company is listed with a harbour-level trust tier on the B2B platform, indicating a baseline verification of its business registration and operational address.

The supplier’s profile shows a response rate of 0 % and no recorded average response time, suggesting that buyers should establish clear communication channels early in the negotiation. The company advertises a full-range of conveyor components, including steel and HDPE rollers, rubber disc impact rollers and custom-designed frames, but does not disclose specific certifications or annual turnover.
