Black Oxide Flanged Shaft Bushing

Designed for the assembly of non-standard mechanical transmission and positioning components, this shaft bushing features a central through-hole and end-face mounting characteristics. With a square outer profile and circular inner bore, the part achieves rigid fixation via four countersunk screw holes on the end face. It is commonly used in motor mounts, bearing supports, or precision fixture connections to ensure a secure interface between rotating components and the machine frame.

During machining, strict control is maintained over the coaxiality of the inner hole and outer contour, as well as the flatness of the mounting surface, to guarantee positional accuracy and uniform load distribution after assembly. For such irregular block-shaped parts with chamfers and stepped surfaces, our factory utilizes CNC machining centers for multi-face milling. This ensures precise consistency across all feature dimensions, meeting the stringent interchangeability requirements of automated equipment.

Leveraging the manufacturing capabilities of Shenzhen Chaozhuo Quick Technology Co., Ltd., we offer custom production in materials such as carbon steel, stainless steel, and aluminum. The black matte finish, typically achieved through blackening or anodizing processes, not only enhances visual consistency but also improves corrosion resistance. Buyers can specify tolerance bands and surface treatment standards via 3D drawings, allowing us to evaluate the machining plan and provide accurate quotes and lead time support.
