Zoom 0.5mm 440c Stainless Steel Ball
The Zoom 0.5mm 440c Stainless Steel Ball is a miniature precision component supplied by Zhong Shan H.R.T. Precision Steel Ball Co., Ltd. (China). It is manufactured from martensitic-type AISI 440C stainless steel, a material recognised for excellent corrosion resistance. The ball measures exactly 0.5 mm in diameter and is offered in grades G10, G25, G100 and G500, complying with AFMBA 10 or DIN 5401 standards. Hardness is specified between HRC 58 and HRC 65, and the supplier can provide the balls in vacuum-melt condition on request.
AISI 440C typically contains about 0.95 % carbon and 13 % chromium, giving the alloy its high wear resistance and ability to retain hardness after heat treatment. Standard industry tolerances for 0.5 mm balls are +/-0.001 mm on diameter and a sphericity of 0.2 µm, which the supplier’s grade G10-G500 series meets. Surface finish is usually Ra 0.02 µm or better, providing low friction in high-speed bearing assemblies. Typical packaging for such miniature balls is in sealed polymer bags containing up to 10 000 pieces, protecting against contamination.
These balls are commonly used in precision bearings, aerospace actuation mechanisms, medical devices and pump valves where both corrosion resistance and high hardness are required. Importers should verify the supplier’s ISO-9001 and TS-16949 certifications and request a material test report for the specific grade needed. Trade terms, minimum order quantities and lead times are not listed, so buyers must confirm them directly with the supplier before placing an order.
