These 440 stainless steel angular contact ball bearings are built for exactly those conditions — delivering reliable axial and radial load handling where moisture and corrosion are constant concerns.\u003c\/p\u003e\n\u003cp\u003eEach bearing in this single-row series is manufactured from 440-grade stainless steel for both the inner and outer rings as well as the rolling elements. The series spans nine sizes from S7001AC (12×28×8 mm \/ 0.47\"×1.10\"×0.31\") through S7009AC (45×75×16 mm \/ 1.77\"×2.95\"×0.63\"), covering a wide range of shaft diameters. The AC designation indicates a 15° nominal contact angle, optimizing the bearing for combined axial and radial loading at elevated speeds.\u003c\/p\u003e\n\u003cp\u003eTypical applications include high-speed spindles in CNC machining centers, centrifugal pumps handling corrosive fluids, food-processing conveyor shafts requiring washdown resistance, and laboratory or medical equipment where contamination from rust particles is unacceptable. The stainless construction also makes these 440 stainless steel angular contact ball bearings a reliable choice for marine deck hardware and offshore instrumentation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatibility Note:\u003c\/strong\u003e These bearings follow ISO 15° AC contact-angle geometry.
