Material & Tolerance
The standard material is listed below; also available in steel, stainless, brass and aluminium. Dimensions in mm; tolerances machined to ISO. Deviations (mm) are given for the nominal diameter according to the ISO 286-2 tables; thread tolerances (6g/6H) are to ISO 965. For custom sizes/tolerances, contact us with the part code.
Manufacturing Scope
Conical Fitting End is a Fittings family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀9.2–19.6 mm, lengths 16–33 mm, standard material Stainless Steel (also 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 RAKB-KNU-10 at 33 mm. Besides turning, the family requires thread turning (7 sizes from M5 to M12x1.5), hex flat milling (AF 8–17), taper turning and axial drilling (⌀2–6.5 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 RAKB-KNU-07: 17 mm long at ⌀9.2 mm, L/D 1.8. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to 6g tolerance; the smallest is RAKB-KNU-07 (⌀9.2 mm) and the largest RAKB-KNU-10 (⌀19.6 mm). The family includes threaded, hex-drive, tapered, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
