About the Airtac ACE Compact Cylinder ACE25X80S
This AirTAC ACE25X80S is a double acting ISO 21287 compact cylinder with a 25 mm bore and 80 mm stroke, delivering 245.4 N of push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guard enclosures where a full-length cylinder would not. The S45C piston rod is hard-chrome plated for wear resistance, and a fixed TPU bumper at each end absorbs impact energy.
With the optional -S magnet fitted, this model accepts CMSE or DMSE reed and solid-state switches for position sensing. For real-world sizing, plan for about 15 kg of safe vertical lift at 0.5 MPa (245.4 N divided by 9.81, then halved for a 2:1 safety margin). The M5x0.8 port suits small-bore pneumatic circuits, and the operating pressure range is 0.15-1.0 MPa (22-145 psi) with speeds from 30 to 500 mm/s.

Where the Airtac ACE Compact Cylinder ACE25X80S Is Used
Fixture Clamping
Use the ACE25X80S to clamp small aluminum parts in a CNC milling fixture. The 80 mm stroke clears the workpiece, and the 245.4 N push force holds it firmly during light machining operations.
Carton Tamping
In a packaging line, this cylinder can tamp down folded cardboard boxes before sealing. The compact body fits between conveyor rails, and the 206.2 N pull retracts the tamper quickly for the next cycle.
Guard Door Interlock
Mount the ACE25X80S on a machine safety guard to slide a bolt into a latch. The 80 mm stroke moves the bolt fully, and the optional -S magnet lets a CMSE switch confirm the guard is closed before the machine starts.
Is the Airtac ACE Compact Cylinder ACE25X80S the Right Cylinder?
Choose the ACE25X80S when you need a compact, double acting cylinder with a 25 mm bore and 80 mm stroke. It produces 245.4 N push and 206.2 N pull at 0.5 MPa, which is stronger than the ACE20 (157.1 N push) yet lighter than the ACE32 (402.1 N push) - ideal for mid-range clamping or light pressing tasks. The stroke of 80 mm is within the 150 mm maximum standard stroke for this bore, so no special order is needed. Mounting options include FA/FB flanges, LB foot brackets, CA/CB clevises, and SDB pivots, all compatible with the ISO 21287 face. Since the magnet is fitted, you can directly attach CMSE or DMSE switches for end-of-stroke detection. Remember, this cylinder does not hold its position when air is removed; for load holding, add a pilot check valve or rod lock.
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 ACE25X80S FAQ
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. At 0.7 MPa, push is 343.6 N and pull is 288.6 N. The theoretical maximum force at 1.0 MPa is 50.1 kgf. These values apply to the 25 mm bore with an 80 mm stroke.
The ACE25X80S has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight spaces. It uses a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE sensors to detect the piston position. The body is hard-anodized aluminium with a hard-chrome plated rod for durability.
