Import 5mm 6mm 7mm 8mm Solid Nylon Plastic Balls — Buy in Bulk from Supplier in China

Taian Porei Import & Export Co., Ltd. provides solid nylon plastic balls in 5mm, 6mm, 7mm and 8mm diameters, manufactured from PA66 (polyamide 66) and PA6 (polyamide 6) materials. The balls are available in standard grades G0 to G3, with dimensional tolerances ranging from ±0.01mm to ±0.05mm depending on the grade. These precision-moulded components are designed for low-friction, high-wear applications in mechanical and industrial systems.

Nylon balls are known for their resistance to alkali, petroleum products and a broad selection of chemical substances, making them suitable for use in valves, switches and light-load bearings. The material’s density is approximately 1.1 g/cm³, which is typical for PA66 and PA6, providing a lightweight alternative to metal balls in non-load-bearing applications. Surface finish is usually polished to a Ra 0.2-0.4 micrometre standard, ensuring smooth operation in moving parts.

These balls are commonly used in check valves, light-load mechanical assemblies and control knobs where cost-effectiveness, chemical resistance and moderate hardness are required. They are supplied in bulk packaging, typically in plastic bags or containers, and can be sourced as mixed or single-size orders. Buyers should confirm the exact grade and tolerance requirements for their application, as these directly impact performance and longevity.

Taian Porei Import & Export Co., Ltd. is a China-based supplier specialising in plastic components, including nylon balls. The company holds a harbor trust tier, indicating basic verification of its business registration. Its profile includes a physical address in Taian, Shandong Province, but no recorded response rate or average response time, which may require buyers to follow up on initial enquiries.
