Import Bicycle Steel Balls — Buy in wholesale FOB from Supplier in China

Interest Group Steel Balls Co Ltd., located in Tainan, Shandong Province, China, manufactures carbon steel balls for bicycle hubs and broader mechanical applications. The company produces balls from AISI 1010, 1015, 1045, and 1085 carbon steel grades, with diameters ranging from 3mm to 35mm. Tolerance grades span G100 to G2000 under international standards, determining dimensional precision and suitability for specific bearing applications. The harbour trust tier and zero recorded response rate indicate limited platform engagement data for this supplier. Shandong Province is a significant concentration for Chinese steel ball manufacturing, with established supply chains serving bicycle component makers globally.

The AISI grade selection determines critical mechanical properties for bicycle steel balls. AISI 1010 and 1015 are low-carbon steels offering good formability and weldability, typically used in applications where hardness requirements are moderate and cost sensitivity is high. AISI 1045 is a medium-carbon steel achieving higher tensile strength and hardness through heat treatment, suitable for more demanding load conditions in bicycle hubs and semi-precision bearings. AISI 1085, a higher-carbon grade, can achieve greater surface hardness when properly heat treated, extending wear resistance in high-cycle applications. The G100 to G2000 tolerance classification refers to sphericity, diameter variation, and surface finish, with G100 representing tighter tolerances (typically plus or minus 0.0025mm diameter variation) suitable for higher-precision bicycle bearing assemblies, while G2000 permits greater variation for less critical applications.

Bicycle steel balls from Interest Group Steel Balls Co Ltd. serve hub bearings, bottom bracket bearings, and headset bearings in bicycle assemblies, where uniform load distribution and dimensional consistency affect rotational smoothness and component longevity. Beyond bicycles, the balls find application in automotive semi-precision bearings, casters, locks, drawer slides, roller skates, slides, trolleys, and conveyors. The supplier offers custom packaging and materials development according to customer requirements, with drum or carton bulk packaging as standard export formats. Buyers should verify specific AISI grade availability, heat treatment state, and surface finish for bicycle bearing applications, as these parameters directly influence fatigue life and corrosion resistance in service conditions.

Interest Group Steel Balls Co Ltd. operates from Tainan, Shandong Province, China, with postal code 271000. The company holds a harbour trust tier classification with a recorded 0.00 percent response rate and zero average response hours on the platform, indicating no documented communication activity through standard enquiry channels. The supplier's profile emphasises manufacturing rather than trading, with explicit focus on carbon steel, chrome steel, and stainless steel ball production across precision and commercial grades. There is no disclosed information about year of establishment, factory floor area, number of employees, annual output volume, revenue figures, or specific client relationships.

The source description positions Interest Group Steel Balls Co Ltd. as offering custom material development, custom packaging, and just-in-time international delivery capabilities. The company references bearing balls, caster balls, slide guide balls, valve balls, and precision balls across multiple material categories. Buyers should independently verify production capacity, quality management system certification (ISO 9001 typically), and metrology capability for tolerance grade verification. The Shandong location is consistent with China's concentrated steel ball manufacturing geography, though geographic concentration alone does not confirm individual supplier capability or quality consistency.
