Precision Piston & Cylinder Manufacturing

At AXIOM Precision Engineering, we manufacture a wide range of piston and cylinder components — from hydraulic pistons to pneumatic cylinder liners — on our CNC turning and grinding machines to Ra ≤ 0.4 µm surface quality. Sealing integrity, wear resistance and dimensional accuracy are documented on every part.

AXIOM Piston & Cylinder Manufacturing

Piston & Cylinder Types We Manufacture

Custom piston and cylinder components for every application — from high-pressure hydraulic systems to clean-room pneumatics.

Hydraulic Piston

Hydraulic cylinder pistons manufactured with hardened and honed surfaces, rated up to 400 bar working pressure. O-ring and seal grooves machined to full tolerance.

  • Working pressure: max 400 bar
  • 42CrMo4 / C45 / Stainless
  • Honing Ra ≤ 0.4 µm
Pneumatic Piston

Lightweight, low-friction pneumatic cylinder pistons for working pressures up to 10 bar. Aluminium and stainless steel options; material alternatives suitable for clean rooms and food industry.

  • Pressure: max 10 bar
  • Aluminium / Stainless 316L
  • ISO 6432 / ISO 15552 compliant
Cylinder Liner

Engine cylinder liners and custom hydraulic cylinder tubes; inner surface honed to Ra ≤ 0.4 µm with IT6 cylindricity tolerance. Cast iron, steel or stainless options available.

  • Inner diameter: Ø20 – Ø500 mm
  • Honing IT6 tolerance
  • Cast iron / Steel / 316L
Double-Acting Cylinder

Double-acting cylinder bodies applying active pressure in both forward and return strokes. Preferred for automotive and heavy industry applications requiring high force and precise control.

  • Pressure: max 350 bar
  • Diameter range: Ø32 – Ø320 mm
  • ISO 6020-2 compliant flange
Single-Acting Cylinder

Cylinder components applying pressure in one direction only, with return movement provided by spring or gravity. Ideal for clamping and holding systems requiring compact design and low energy consumption.

  • Compact body geometry
  • Spring force calculation included
  • Aluminium & steel options
Custom Profile Piston

Fully bespoke piston and cylinder solutions for applications requiring non-standard dimensions, materials or sealing designs. Special variants for defence, medical and energy sectors.

  • FEA-assisted design
  • PEEK / Ti-6Al-4V options
  • Delivery with certificate
Process

Our Manufacturing Process

In our piston and cylinder manufacturing, dimensional accuracy, surface quality and sealing integrity are controlled and documented at every stage. Fast transition from prototype to series production is ensured.
