Hub Spacer With Circular Spoked Mounting Spacer and Peripheral Alignment Tabs

Drone motor mounts, automotive sub-frame standoffs, and medical device sensor mounting rings use a circular spoked mounting spacer where hub bore diameter tolerance and spoke end tab true position together determine shaft fit and bolt pattern alignment; hub bore outside H7 tolerance prevents hub-to-shaft engagement under installation force, while spoke end tab position outside ±0.1 mm from the bolt circle nominal displaces the tab centreline off the mating hole and prevents simultaneous engagement of all mounting bolts without generating bending moment at the spoke roots. Foshan Zhengshang Precision Hardware (Foshan, Guangdong, ISO 9001, ISO 14001, ISO 45001 certified) turns and mills this hub spacer with circular spoked mounting spacer and peripheral alignment tabs at their roughly 2,000 m² Foshan facility using milling & turning and CNC milling, with hub bore diameter, spoke end tab position, and spacer face flatness confirmed to your drawing requirements at first-off inspection. Zhengshang serves automotive, medical equipment, drones, energy storage, and fastener circular spoked mounting spacer applications. Provide hub bore, tab position tolerance, spacer face flatness, and material and your drawing for quoting. For a production quote from our foshan facility. Applications cover communication, fasteners, and toys and gifts industry.
