Coupling Sleeve with Knurled Cylindrical Knob and Hollow Body, Splined Bore, End Slots

Material selection(aluminium alloy, steel, or brass)determines knurl grip torque and bore wear resistance for this knurled cylindrical knob with hollow body, splined bore, and end slots. Knurl OD and splined bore width are checked against your released print at initial sample inspection; knurl OD governs grip and retention force, and splined bore width determines shaft engagement without rocking. Both are logged in the production record before dispatch. End markets span automotive, aerospace, and medical equipment. Machined at Welltop's Dongguan facility under ISO 9001 controls via CNC milling and turning, the cylindrical body, splined bore, and end slot geometry are produced from your signed-off print. Bore roundness and knurl pattern pitch are verified during in-process sampling. Applications span consumer electronics control knobs, drone gimbal adjusters, and OEM instrument dial assemblies. The facility spans around 4,000 m².
