Airtac ACED Double-acting Compact Cylinder ACED20X25
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X25 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED20X25
The ACED20X25 is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A 10 mm rod exits both covers, so output force is equal in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on every stroke, because both sides work on the rod-side area. The hard-anodized aluminium body with S45C hard-chrome plated rod and a fixed TPU bumper at each end keeps the unit serviceable and quiet at 30-500 mm/s.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs, guards and gantries. In practice, plan on roughly 70 N of usable work at 0.5 MPa (about 0.6 of the rating), which is the equivalent of lifting about 6 kg vertically with a 2:1 margin. The through-rod resists rotation and side load, and the back-end rod can carry a sensor flag. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face.

Where the Airtac ACED Double-acting Compact Cylinder ACED20X25 Is Used
Push-pull fixture clamping
The symmetric through-rod lets a small jig clamp and release from the same bore with equal 117.8 N force in both directions at 0.5 MPa, ideal for 25 mm-stroke workholding on CNC fixtures.
Gantry flag sensing
With the optional -S magnet ordered, CMSE / DMSE switches read position along the body, and the rear rod can carry a mechanical flag for vision or PLC checks on pick-and-place gantries.
Lab dosing slide
A 25 mm stroke at 30-500 mm/s suits reagent tray indexing and sample slides in compact analysers, where the short ISO 21287 body fits inside a guarded benchtop frame.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X25 the Right Cylinder?
For a 25 mm stroke at this force class, the ACED20X25 delivers 117.8 N both ways at 0.5 MPa; step down to the ACED16X25 (75.4 N) for lighter clamps or up to the ACED25X25 (206.2 N) when the load grows. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must be held. Rod end is female M6x1.0 and the port is M5x0.8; the max standard stroke for this bore is 100 mm, so 25 mm is a stock length. Position sensing needs the optional -S magnet code with CMSE / DMSE switches - without -S there is no magnet fitted.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACED Double-acting Compact Cylinder ACED20X25 FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal both ways: 117.8 N at 0.5 MPa, 164.9 N at 0.7 MPa, with a maximum of 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 20 mm bore takes an M5x0.8 port with a female M6x1.0 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and fixed TPU bumpers absorb end-of-stroke energy at both ends. For switching, order the optional -S magnet code - only then can CMSE / DMSE reed or solid-state switches be mounted on the body; without -S the cylinder carries no magnet.
