Lens Cell Barrel
Stepped externally threaded lens cell barrel with a seating bore shoulder.
Manufacturing Scope
Lens Cell Barrel is a Opto-Mechanical Parts family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀12–20 mm, lengths 13–26 mm, standard material Aluminium (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 OPTA-LCB-16T at 26 mm. Besides turning, the family requires thread turning (6 sizes from M8 to M18), taper turning and knurling. Bores in this family run ⌀6–15 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 OPTA-LCB-10L: 23 mm long at ⌀14 mm, L/D 1.6. 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 OPTA-LCB-08 (⌀12 mm) and the largest OPTA-LCB-18 (⌀20 mm). The family includes threaded, tapered, knurled, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
