About the Airtac ACE Compact Cylinder ACE25X150SB
This AirTAC ACE25X150SB is a double acting compact cylinder built to ISO 21287, with a 25 mm bore and a 150 mm stroke. It delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, so it suits light assembly and clamping tasks. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which lets it fit into tight machine guards and compact jigs. The body is hard-anodized aluminium with an S45C hard-chrome rod, and the fixed TPU bumper at each end absorbs end-of-stroke energy.
This model includes the optional -S magnet, so you can mount CMSE or DMSE reed or solid-state switches for position sensing. The M5x0.8 port is standard for this bore. For a safe working load, plan for about 147 N of real work at 0.5 MPa, which is roughly 15 kg of vertical lift with a 2:1 safety margin. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s.

Where the Airtac ACE Compact Cylinder ACE25X150SB Is Used
Compact Jig Clamping
Use the ACE25X150SB to clamp small parts in a CNC fixture where the short ISO 21287 body fits under a workholding plate, and the 245.4 N push force holds components securely during drilling or milling.
Carton Tucking
In a packaging line, this cylinder can tuck flaps or push light cartons along a guide rail. The 150 mm stroke provides enough travel for indexing, and the optional magnet lets a PLC confirm each cycle.
Guard Door Interlock
Mount the ACE25X150SB on a machine guard to actuate a small interlock pin. The compact body saves space on the frame, and the 206.2 N pull force at 0.5 MPa retracts the pin reliably.
Is the Airtac ACE Compact Cylinder ACE25X150SB the Right Cylinder?
When sizing, compare this 25 mm bore with the 20 mm bore that pushes 157.1 N at 0.5 MPa for lighter tasks, or step up to the 32 mm bore that pushes 402.1 N at 0.5 MPa for heavier loads. The 150 mm stroke is the maximum standard stroke for this bore, so it is a made-to-order option if you need longer travel. This model has a male rod thread (B code) and a PT port thread, so verify your rod coupling and fitting compatibility. The built-in magnet from the -S code enables CMSE or DMSE sensors for reliable position feedback in automated cycles. Remember that this cylinder is double acting and does not hold its position when air pressure is lost; use a rod lock or pilot check valve if you need to hold a load in place.
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 ACE25X150SB 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. The bore is 25 mm, the rod is 10 mm, and the port is M5x0.8.
The ACE25X150SB has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. This makes it ideal for fitting inside machine guards, under conveyors, or in compact gantries. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors for position detection.
