Hydraulic & Pneumatic Piston Parts Manufacturing

CNC Swiss turning of hydraulic & pneumatic piston parts on the Goodway SW-20: rod ends, plunger pistons, orifices, gland nuts. 15 families, 144 types, ⌀4–20 mm. Quote by drawing.

Manufacturing Scope

These rotating parts run inside hydraulic and pneumatic cylinders and are used in construction and agricultural machinery, presses and automation lines, furniture machines and general machine building. The category spans 15 families: piston rod end, pusher rod, plunger piston, adjustment spindle, spring pusher, rod eye stud, tapered guide rod, cylinder head bushing, sealing ring, guide and threaded guide bushings, orifice restrictor, throttle screw, back-up ring support and gland nut. On surfaces that directly affect sealing — such as the plunger piston and guide bushings — we hold h6/H7 fit tolerances and, where required, ±0.01 mm precision with a ground cylindrical surface. We machine steel, stainless steel, brass and aluminum, turning the O-ring seat, threaded body, hex wrench flat and conic chamfer in a single setup. Production runs on the Goodway SW-20 Swiss-type lathe in the ⌀4–20 mm range. Alongside 144 standard types, we manufacture custom piston parts to your technical drawing. Pricing is by quote — specify the part, material and quantity to request one.

The defining part here is HIDA-ITM-04 at L/D 10 — the slenderness a sliding-head lathe is built for. Lengths across the 144 variants run 3–120 mm, the longest being HIDA-ITM-16 at 120 mm, still inside the 207 mm single-setup limit. Operations: 60× thread turning, 27× hex flat milling, 76× axial bore, 27× taper turning, 12× knurling.

108 of the 144 variants reference a DIN or ISO standard; the tolerance classes in use are 6H, 6g, H7, H8, f7, h6, h7, h8, h9.

Every part is CNC-turned to your drawing — series, small batches and custom turned parts. Send your drawing (PDF/DWG/STEP) for a quote.

These parts are turned from bar stock in a single setup on the Goodway SW-20 CNC Swiss-type lathe. The threaded end, stepped body and conic chamfer are machined in the same operation; the sealing-critical cylindrical surface of the plunger piston is ground where needed to reach the required surface finish and diameter tolerance. The Swiss-type design gives runout-free, repeatable production on thin, long shafts in the ⌀4–20 mm range.
