About the Airtac ACE Compact Cylinder ACE25X75SB
This AirTAC ACE25X75SB is a double acting ISO 21287 compact cylinder with a 25 mm bore and a 75 mm stroke, delivering 245.4 N of push force at 0.5 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight automation cells where space is at a premium.
With the optional -S magnet 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 demanding cycles, while the fixed TPU bumper absorbs end-of-stroke impact. As a practical guide, plan for about 147 N of usable force at 0.5 MPa, which lifts roughly 15 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE25X75SB Is Used
Fixture Clamping
Use in a machining fixture to clamp small parts with 245.4 N force at 0.5 MPa, ensuring stable positioning during drilling or milling operations.
Label Applicator
Drive a label applicator head in a packaging line, where the 75 mm stroke and compact body fit within tight guard rails and cycle at speeds up to 500 mm/s.
Sorting Gate
Actuate a diverter gate on a conveyor, using the fitted -S magnet with a DMSE sensor to confirm the gate position for reliable sorting of products.
Is the Airtac ACE Compact Cylinder ACE25X75SB the Right Cylinder?
For lighter duty, the ACE20X75 offers 157.1 N push at 0.5 MPa, while the ACE32X75 provides 402.1 N push for heavier loads. This 25 mm bore version balances compactness and force, suitable for clamping, pressing, or positioning tasks in small fixtures. Since it is double acting, air both extends and retracts the rod; for holding a load when air is lost, add a rod lock or pilot check valve. The male rod thread (B) simplifies mounting with rod-end accessories, and the M5x0.8 port suits small-bore air circuits.
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 ACE25X75SB FAQ
At 0.5 MPa, the push force is 245.4 N and pull is 206.2 N. At 0.7 MPa, push is 343.6 N and pull is 288.6 N. The theoretical maximum force is 50.1 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and speed is 30-500 mm/s.
No, the magnet is optional. This model includes the -S option, so it has a built-in magnet for use with CMSE or DMSE switches. Without the -S code, there is no magnet. The cylinder has a fixed TPU bumper at both ends, not an adjustable cushion, and it does not lock or hold a load when air pressure is lost.
