About the Airtac ACE Compact Cylinder ACE50X25SH
This AirTAC ACE50X25SH is a double acting compact cylinder that delivers 981.7 N of push force at 0.5 MPa, with a pull force of 881.2 N on retraction. Its ISO 21287 short body takes up about half the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length unit will not.
A practical rule for sizing is to plan for about 589 N of real work at 0.5 MPa, which translates to lifting roughly 60 kg vertically with a 2:1 safety margin. The optional -S magnet is fitted on this model, so CMSE or DMSE reed and solid-state switches can be mounted directly to sense the piston position. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling applications.

Where the Airtac ACE Compact Cylinder ACE50X25SH Is Used
Fixture Clamping
Use the ACE50X25SH to clamp sheet metal parts in a CNC machining fixture. The 981.7 N push force at 0.5 MPa holds thin workpieces securely, while the compact body fits between vise jaws and spindle guards.
Carton Ejection
Mount this cylinder on a packaging line to push filled cartons off a conveyor onto a transfer chute. The 25 mm stroke is enough to clear the belt edge, and the short body keeps the mechanism inside the machine guard envelope.
Press Ram Stop
In a small pneumatic press, use the ACE50X25SH as a stop pin that extends to block a sliding die carrier. The 881.2 N pull force retracts the pin quickly, and the TPU bumper prevents shock to the frame at high cycle rates.
Is the Airtac ACE Compact Cylinder ACE50X25SH the Right Cylinder?
For lighter duty in the same compact footprint, the ACE40X25 offers 628.3 N push at 0.5 MPa, while stepping up to the ACE63X25 gives 1558.6 N push for heavier clamping or pressing tasks. This 50 mm bore with a 25 mm stroke is a balanced choice for medium-force operations where space is limited. The fixed TPU bumper at both ends absorbs end-of-stroke impact, but it does not hold a load if air pressure is lost, so use a rod lock or pilot check valve for vertical applications that must stay put. The 1/8" port and M10x1.5 female rod thread match standard fittings and attachments, and the -S magnet enables position sensing with CMSE or DMSE switches.
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 ACE50X25SH FAQ
At 0.5 MPa, the push force is 981.7 N and the pull force is 881.2 N. At 0.7 MPa, push increases to 1374.4 N and pull to 1233.7 N. The theoretical maximum force at 1.0 MPa is 200.2 kgf. These numbers are based on the 50 mm bore and 16 mm rod, with a 1/8" port.
The ACE50X25SH saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight spaces. It has a fixed TPU bumper at both ends to absorb impact, but it is not an adjustable cushion. This model includes the optional -S magnet, so you can mount CMSE or DMSE reed or solid-state switches to detect piston position.
