Description:
Our stainless steel sleeve bushings are meticulously CNC-machined from premium 304, 316, or 17-4 PH stainless steel to deliver exceptional wear resistance and long-term durability. Utilizing state-of-the-art turning, milling, and precision grinding, we maintain tolerances as tight as ±0.005 mm and achieve flawless surface finishes. Engineered to withstand harsh environments, these corrosion-resistant components are ideally suited for industrial machinery, automotive systems, and aerospace assemblies. Backed by comprehensive OEM and custom manufacturing services, we offer expert design consultation, rapid prototyping, and scalable production runs. All parts conform to ASTM specifications and are fully customizable to your exact requirements.
