Material: Stainless steel (Inox/Stainless steel). This material is recognized by its silver-gray color, high gloss and surface appearance. Stainless steel is often chosen for its excellent corrosion resistance, high mechanical strength and bio-protection (important in the food and pharmaceutical industries). Machining method: Precision machining, mainly CNC turning (CNC Turning) to make a perfectly circular symmetrical shape. Study and configuration features: Cylinder body: Is a long, solid cylinder or drum (in this case, drum), machined to a polished finish. The long cylinder body can be customized according to the application. Flange: Is a circular disc, integrated into the block at one end of the cylinder body. This surface is designed to assemble and fix the part to the machine frame, box or other surface. Mounting/Location Error: The surface has information errors (bolt holes) (about 3-4 errors) evenly distributed on the circle, used for fixed fixing. Pad Error/Center Error: The center of the part is a hollow, precisely machined cylindrical hole, used to mount the rotating shaft, the pipe or to contain other parts (such as bullets/ball bearings). Inside the hollow cylinders, there are also one or more small thread errors (e.g. 2 thread errors in the picture) near the edge, used for positioning, pinning or tightening inside (e.g. locating screws). Application: Drive System: Used as a bearing/fixture for the rotating screw shaft in industrial machinery. Machine/Valve: Used as a connecting part or as a cover for the cylindrical shaft. Industrial/Automation Equipment: Is an important part in the assembly, connection and positioning of mechanical components in harsh environments or high ecological protection requirements.
