Threaded Reduction Bush (Female-Female)
Bored reduction bush with internal threads of different sizes tapped from each end.
Manufacturing Scope
Threaded Reduction Bush (Female-Female) is a Nuts & Adapters family precision-turned on a Goodway SW-20, covering 7 variants — diameters ⌀9–20 mm, lengths 10–20 mm, standard material Brass (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.
The family is machined from ⌀20 mm bar stock; its longest variant is SOMB-RBC-10 at 20 mm. The family is produced by turning alone. Bores in this family run ⌀4.2–10.2 mm. All of it is completed in a single setup, without the part leaving the machine.
The variant with the highest length-to-diameter ratio is SOMB-RBC-02: 12 mm long at ⌀10 mm, L/D 1.2. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to 6H tolerance; the smallest is SOMB-RBC-01 (⌀9 mm) and the largest SOMB-RBC-10 (⌀20 mm). The family includes bored variants. Custom sizes, tolerances or materials are produced to the part code on request.
This is a dimension schematic, not a manufacturing drawing. Dimensions match the catalog data; request a quote with the part code to confirm before production.
