Aisi440c 1.588mm G10 Steel Ball For Ball Bearing
The Aisi440c 1.588mm G10 precision steel ball is a miniature martensitic stainless steel sphere manufactured for high-precision ball bearing assemblies. This grade meets AFBMA standards for sphericity and surface finish, with a diameter tolerance held to ±0.0025mm for G10 classification. The material, AISI 440C, contains 0.95-1.2% carbon, delivering hardness up to 60 HRC and superior wear resistance in dynamic applications.
Martensitic stainless steel 440C is selected for its corrosion resistance in mildly aggressive environments and its ability to retain hardness at elevated temperatures. Typical industry specifications for G10 balls include a surface roughness of Ra 0.025μm or better and a sphericity deviation below 0.25μm. These balls are often supplied in anti-rust oil or dry packaging, with standard lot sizes of 1000 or 10000 units per bag.
Common applications include miniature bearings for medical devices, aerospace instrumentation, and precision motors where low friction and long service life are critical. Buyers typically source these balls in bulk for OEM assembly, with incoterms like FOB Shenzhen or CIF destination port. Packaging is usually vacuum-sealed to prevent oxidation during transit, and buyers should confirm the availability of AFBMA or ISO 3290 certification for their quality assurance process.

Sourcing Aisi440c 1.588mm G10 Steel Ball For Ball Bearing from Zhongshan Qian Run Precision Steel Ball Co., Ltd. - China Import Guide
Before ordering, verify the supplier’s adherence to AFBMA or ISO 3290 standards for the G10 grade, as these certifications ensure the balls meet precision requirements. Confirm the sphericity and surface roughness values, as deviations can impact performance in high-speed or high-load applications. Request a material test report to validate the carbon content and hardness of the AISI 440C steel.
Discuss logistics options, including FOB Shenzhen or CIF to your destination port, and clarify packaging preferences such as vacuum-sealed bags or anti-rust oil. Lead times for precision steel balls can vary, so confirm production schedules and shipping timelines. Payment terms like T/T or L/C should be agreed upon in advance, with clear milestones for deposits and final payments.
Conduct quality checks upon receipt, including dimensional inspection with calipers or optical comparators to verify the 1.588mm diameter and G10 tolerance. Perform a surface roughness test using a profilometer to ensure Ra ≤0.025μm. Inspect packaging for damage or oxidation, and retain documentation such as certificates of conformance and material test reports for traceability.
