440C Stainless Steel Bearings


As a standard, all stainless steel bearings, rings, and steel balls are processed by AISI SUS440C (9 Cr18Mo or 9 Cr18) vacuum quenching. All retainers and seals are made of AISI304 or AISI316, and they are guaranteed to measure up to the ISO ABEC-5 standard and vibration level Z3.

Lily bearings provide high performance, AISI440C stainless steel bearings on the basis of corrosion resistance, as well as high precision and wear resistance of chrome steel. 440 stainless steel bearings are one of the most extensively applied stainless steel bearings. The advantages include inexpensiveness, high solidity, and high load and speed endurance. Disadvantages include poor rust and corrosion resistance.
