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
Plain Ferrule is a Custom Turned Parts family precision-turned on a Goodway SW-20, covering 11 variants — diameters ⌀6–20 mm, lengths 8–32 mm, standard material Brass (also steel, stainless steel 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 OZEB-FRL-20 at 32 mm. The family is produced by turning alone. Bores in this family run ⌀3.2–14 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 OZEB-FRL-08: 17 mm long at ⌀9 mm, L/D 1.9. 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 OZEB-FRL-05 (⌀6 mm) and the largest OZEB-FRL-20 (⌀20 mm). The family includes bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
