This precision CNC machined two-piece rotary housing assembly is purpose-engineered for medical device and surgical instrument applications demanding exceptional structural strength, precise rotational motion control, and long-term surface durability under rigorous clinical operating conditions.
Material & Performance
Manufactured from Aluminum Alloy 7075, this aerospace-grade material delivers outstanding tensile strength, superior fatigue resistance, and excellent dimensional stability. It provides a significantly stronger and more reliable structural solution than conventional 6061 alloy for high-load medical motion control and robotic surgical system components.
Design Features
Precision-turned upper cap with conical funnel-bore aperture for accurate specimen or instrument introduction
Precision-ground mating interface between upper and lower bodies ensuring smooth, controlled relative rotation with minimal axial play
Lower cylindrical base incorporating circumferential array of radially distributed threaded and through-ports for multi-point mounting attachment, pneumatic actuation, or sensor integration
All mating surfaces machined to tight concentricity tolerances within ±0.003mm
The assembly ensures frictionless rotational performance and accurate angular positioning critical to surgical robotic actuators and precision diagnostic instrument platforms.
Surface Finish & Durability
The natural Type II anodizing finish produces a dense, uniform aluminum oxide layer that is non-toxic, chemically stable, and fully compliant with ISO 10993 biocompatibility standards. The anodized surface withstands repeated autoclaving, disinfectant exposure, and clinical washdown protocols without surface degradation or dimensional change.
Quality Assurance
All components are manufactured under ISO 13485 certified quality systems with full CMM verification, anodizing thickness testing, rotational fit inspection, and complete material traceability documentation per batch.
