Precision Special Steel 52100 Bearing Steel Bars
The product is a precision‑machined bearing steel bar made from AISI 52100, EN31 or 100Cr6 high‑carbon chromium alloy. It is supplied in diameters from 20 mm up to 600 mm and lengths between 1 000 mm and 6 000 mm, complying with ASTM A295 and JIS G4805 standards. The bars are intended for high‑performance ball and roller bearing manufacturing and are packed for export in standard wooden crates.
AISI 52100 steel offers a carbon content around 1.0 % and chromium near 1.5 %, giving a typical hardness of 62‑65 HRC after oil‑quench and tempering. In the bearing industry this grade is favoured for its wear resistance and fatigue strength, with a typical tensile strength of 1 900‑2 100 MPa. Surface finish is commonly delivered at Ra 0.2 µm, and diameter tolerances are usually ±0.02 mm for sizes up to 100 mm and ±0.05 mm for larger dimensions.
Typical buyers include automotive bearing manufacturers, aerospace component makers and industrial machinery producers. The supplier states flexible minimum order quantities and mentions compliance with ISO and SGS certifications, but exact MOQ and lead time should be confirmed directly. Prospective importers are advised to request the material test report and verify packaging details before finalising the contract.
