Airtac ACED Double-acting Compact Cylinder ACED125X200SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X200SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 200mm stroke, 1/4" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACED Double-acting Compact Cylinder ACED125X200SB
The ACED125X200SB is a double acting, double-rod ISO 21287 compact cylinder: a 25 mm rod exits both covers, so thrust is identical on every stroke - 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction, peaking at 1201.3 kgf at 1.0 MPa. Because the through-rod is symmetric, the piston resists rotation and side load, and the rear rod can carry a sensor flag or drive a second fixture. Air supply is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, running 30-500 mm/s over a 200 mm stroke.
The hard-anodized aluminium body with S45C hard-chrome-plated rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, letting this 125 mm bore slot into heavy press fixtures and gantries where a full-length body will not fit. At 0.5 MPa, plan on about 3534 N of real work (roughly 360 kg of vertical lift, halved to 180 kg for a 2:1 margin). The -S magnet is fitted on this model, so CMSE / DMSE switches mount directly in the body slots, and a fixed TPU bumper at each end absorbs end-of-stroke shock.

Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø125mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 5890 N |
| 0.7 MPa | 8247 N |
| Max (@1.0 MPa) | 1201 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED125X200SB Is Used
Heavy press and forming fixtures
The 5890.5 N symmetric thrust at 0.5 MPa suits aluminium die spotting and riveting heads where equal force is needed on both the approach and return stroke.
Reciprocating transfer beams
A rod on each cover lets the through-rod push a pallet lift from either side of a 200 mm stroke conveyor gantry, resisting the rotation a single rod would allow.
Position-verified clamping stations
With the fitted -S magnet, CMSE or DMSE switches confirm full clamp and full retract on machining-centre fixtures running 0.15-1.0 MPa (22-145 psi) air.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X200SB the Right Cylinder?
At 5890.5 N per direction at 0.5 MPa, this bore sits at the top of the ACED range - step down to ACED100 for 3769.9 N or up from ACED80 at 2356.2 N. The 200 mm stroke is within the 300 mm standard limit for bore 125, so no made-to-order build is needed. Note that with air lost the piston drifts freely; add a rod lock or pilot check valve if the load must stay put. FA/FB flanges, LB foot and FTC brackets plus I and Y rod knuckles bolt straight to the ISO 21287 face, and the male (B) rod thread suits externally clamped tooling.
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 ACED125X200SB FAQ
Output is equal in both directions because both strokes use the rod-side area: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa each way, with a maximum of 1201.3 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed range 30-500 mm/s over the 200 mm stroke.
The ISO 21287 short body cuts about 50% of the mounting length of an ISO 15552 profile cylinder, so the 125 mm bore fits tight machine frames. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for end-of-stroke signalling. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA/FB flange, LB foot or FTC mounts bolt directly to the standard face.
