Automotive Bearing Sleeves

The Automotive Bearing Sleeves are precisely machined from 6061-T6 aluminum alloy and have a short cylindrical structure with high inner hole smoothness, ensuring a regulated adjustment with the outer ring or the bearing capital and a soft function; There is a diamond shaped rolling area in the middle of the outer cylindrical surface, which has been finely embossed on the surface to significantly improve the friction and anti slip performance during manual assembly, making it easy to install/disassemble by hand or use as a manual adjustment ring.Smooth both ends and chamfered edges to avoid stress concentration and assembly scratches.

Step 1: The product forming process is rigorous and precise, with custom aluminum CNC Turning as the core technology. First, the standard aluminum stem 6061 is selected for the rugged machining to quickly remove excess materials, and and the cylindrical shape, inner hole contour, and end face step of the bearing sleeve are preliminarily machined, which leaves a reasonable margin for later precision mechanization.

Step 2: Use the Precision CNC Turning Services for the semi-precision and precision tournament, close the tolerances step by step, control the coaxiality, the cylindricality and dimensional accuracy of the inner openings and outer circle strictly and ensure that key mating surfaces achieve micrometer level accuracy. Subsequently, a special rolling tool is used on the lathe to form a single anti slip cross rolling texture, which ensures uniform consistency. Then, the edges and holes are chamfered and deburred to eliminate stress concentration and improve assembly safety and appearance quality.

Step 3: After the machining is completed, the CNC turning parts enter the anodizing process, which includes several phases such as degreasing, alkaline corrosion, neutralization, comprising oxidizing and sealing the holes to form a dense sky blue oxide film on the surface, which significantly improves wear and corrosion resistance.
