Manufacturing Scope
Bored Spacer Washer is a Spacers & Standoffs family precision-turned on a Goodway SW-20, covering 11 variants — diameters ⌀6–20 mm, lengths 4–18 mm, standard material Steel (also stainless steel, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request a quote with the code you need.
The family is machined from ⌀20 mm bar stock; its longest variant is ARAB-BOR-20 at 18 mm. The family is produced by turning alone. Bores in this family run ⌀3.2–10.5 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 ARAB-BOR-20: 18 mm long at ⌀20 mm, L/D 0.9. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to h9 tolerance; the smallest is ARAB-BOR-06 (⌀6 mm) and the largest ARAB-BOR-20 (⌀20 mm). The family includes bored variants. Custom sizes, tolerances or materials are produced to the part code on request.
