Custom CNC Turned Stainless Steel Multi-Hole Spacer Sleeve, Precision Circular Connecting Collar | Chenrong Precision

Product Overview

This custom CNC turned stainless steel multi-hole spacer sleeve is a precision circular mechanical component with evenly distributed through holes. It is manufactured by high-precision CNC turning to guarantee concentricity and consistent hole position tolerance. The brushed machined surface offers good wear resistance and corrosion resistance. Widely used as spacer ring, connecting collar and positioning part for automation equipment, mechanical assemblies and transmission systems. We accept custom manufacturing according to your CAD drawings or samples, supporting prototype and small batch orders.
