Plunger Piston

Manufacturing Scope

Plunger Piston is a Hydraulic & Pneumatic Pistons family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀6–20 mm, lengths 24–67 mm, standard material Stainless Steel (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 HIDA-DLP-20 at 67 mm. Besides turning, the family requires thread turning (M8), taper turning and axial drilling (⌀4 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 HIDA-DLP-06: 24 mm long at ⌀6 mm, L/D 4.0. This ratio is achievable on a conventional lathe as well; the sliding-head advantage in series work is that the part never leaves the machine, so the size does not drift from variant to variant.

Variants are machined to h6 tolerance; the smallest is HIDA-DLP-06 (⌀6 mm) and the largest HIDA-DLP-20 (⌀20 mm). The family includes threaded, tapered, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
