About the Airtac ACE Compact Cylinder ACE80X250S
This AirTAC ACE80X250S is a double acting compact cylinder that uses air to both extend and retract its 20 mm rod. It delivers a 2513.3 N push and 2356.2 N pull at 0.5 MPa, making it a strong choice for medium-duty automation. The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames where a longer cylinder would not.
With the optional -S magnet already fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. For a safe working load, plan for about 1508 N of real work at 0.5 MPa, or roughly 154 kg lifted vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE80X250S Is Used
Machine Guard Door
Move a 40 kg polycarbonate guard door on a CNC mill. The 250 mm stroke and 2513.3 N push at 0.5 MPa open and close the door smoothly, while the short body fits the machine's frame profile.
Parcel Stop Gate
In a parcel sorting line, this cylinder raises a 300 mm long stop gate to divert boxes weighing up to 20 kg. The 2356.2 N pull retracts the gate quickly, and the optional -S magnet signals the gate position to the PLC.
Press Feed Pusher
On a small stamping press, push metal blanks from a magazine into the die area. The 250 mm stroke covers the feed distance, and the 2513.3 N push at 0.5 MPa handles blanks up to 5 mm thick without stalling.
Is the Airtac ACE Compact Cylinder ACE80X250S the Right Cylinder?
For a lighter application, consider the ACE63X250S with a 1558.6 N push at 0.5 MPa, while the ACE100X250S offers a 3927.0 N push for heavier loads. This 80 mm bore model balances force and size for many industrial tasks. The fixed TPU bumper absorbs end-of-stroke energy but does not hold a load in position; if the load must stay put when air is lost, add a rod lock or pilot check valve. The 1/4" port and M12x1.75 female rod thread match standard ISO 21287 accessories.
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 ACE Compact Cylinder ACE80X250S FAQ
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2356.2 N. At 0.7 MPa, push is 3518.6 N and pull is 3298.7 N. The theoretical maximum force is 512.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The ACE80X250S has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. This lets you install it in machine guards, jigs, or gantries where a full-length cylinder would not fit. The fixed TPU bumper at both ends absorbs impact, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
