Hollow Tube Sleeve With Cylindrical Coupling Sleeve and Radial Through-Holes Chamfered Inner Edges

Bore diameter tolerance and radial through-hole true position drive the acceptance criteria for a hollow cylindrical coupling sleeve with radial through-holes and chamfered inner edges; bore diameter variation above ±0.01 mm changes the clearance or interference fit with the mating shaft and alters torque transmission capacity in drone actuator, automotive sensor, and energy storage drive applications. Radial through-hole position outside ±0.05 mm from the design angular spacing misaligns the locking pin or wire retention feature and prevents simultaneous engagement through the sleeve and shaft holes during assembly. Foshan Zhengshang Precision Hardware (Foshan, Guangdong, ISO 9001, ISO 14001, ISO 45001 certified) turns this hollow cylindrical coupling sleeve with radial through-holes and chamfered inner edges at their roughly 2,000 m² Foshan facility using Swiss machining and milling & turning, with bore diameter, radial hole true position, and chamfer geometry checked to your print requirements at initial sample inspection. Zhengshang serves automotive, medical equipment, drones, energy storage, and fastener cylindrical coupling sleeve applications.
