High Precision Custom CNC Aluminum Bushings Machining Steel Lock Pins For Automotive
Our company specializes in manufacturing high-precision aluminum sleeve bushings and steel lock pins tailored to your exact needs. These parts are designed for demanding applications in the automotive sector, industrial equipment, automation systems, and more. Every component is custom-machined using advanced CNC turning and milling processes to ensure optimal fit, durability, and long-term reliability.
The aluminum bushings are made from pure, high-quality aluminum with a natural finish by default. Optional surface treatments such as anodizing or polishing are available upon request. Standard dimensions are approximately 20mm in length and 10mm in width, but we offer complete customization to suit your unique technical specifications, assembly requirements, or prototype designs.
Our steel lock pins are precision-machined from carbon steel or stainless steel, providing excellent strength and alignment in mechanical assemblies. These pins can be finished with corrosion-resistant coatings, including zinc plating, black oxide, and nickel, depending on the environmental requirements of your application. They're ideal for use in transmission housings, engine systems, equipment frames, and other scenarios where stability and accurate positioning are critical.
