Airtac ACE Compact Cylinder ACE25X25SB
The AirTAC Airtac ACE Compact Cylinder ACE25X25SB is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACE Compact Cylinder ACE25X25SB
This AirTAC ACE25X25SB is a double acting compact cylinder that extends and retracts its rod with air pressure on both strokes, delivering a 245.4 N push and 206.2 N pull at 0.5 MPa. Its ISO 21287 short body cuts the mounting length by about half compared to an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a longer unit will not.
The hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling, while the fixed TPU bumper at each end softens the stop. Because this model carries the optional -S magnet, you can mount CMSE or DMSE reed or solid-state switches for position sensing. For a real part weight, plan on lifting about 15 kg vertically at 0.5 MPa with a 2:1 safety margin, since the theoretical max force is 50.1 kgf at 1.0 MPa.

Where the Airtac ACE Compact Cylinder ACE25X25SB Is Used
Fixture Clamping
Mount the ACE25X25SB in a drill jig to clamp small brackets during hole drilling; the 245.4 N push at 0.5 MPa holds parts firmly, and the compact body fits between vise jaws.
Light Part Ejection
Use it on a packaging line to push finished caps off a conveyor into a chute; the 25 mm stroke clears the part width, and the male rod thread connects to a simple pusher plate.
Guard Door Interlock
Install it on a machine guard to slide a locking pin into place; the double acting action retracts the pin positively, and the optional -S magnet lets a CMSE switch confirm the guard is closed.
Is the Airtac ACE Compact Cylinder ACE25X25SB the Right Cylinder?
Choose the ACE25X25SB when you need a 25 mm bore with a 25 mm stroke and a male rod thread for direct coupling. It produces 245.4 N push and 206.2 N pull at 0.5 MPa, which suits light clamping or pushing tasks; if you need more force, step up to the 32 mm bore that gives 402.1 N push at the same pressure, or drop to the 20 mm bore for 157.1 N push when space is tighter.
The M5x0.8 port is standard for this bore, and the male rod thread (B code) simplifies mounting to a clevis or rod end. Since the magnet is fitted with the -S code, you can add CMSE or DMSE switches for end-of-stroke detection, but remember this cylinder does not hold its position if air pressure is lost - use a rod lock or pilot check valve for load holding.
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 ACE25X25SB FAQ
At 0.5 MPa, it delivers 245.4 N push and 206.2 N pull. At 0.7 MPa, these rise to 343.6 N push and 288.6 N pull. The theoretical maximum force is 50.1 kgf at 1.0 MPa, so for a safe working load at 0.5 MPa, plan for about 147 N (or 15 kg vertical lift with a 2:1 margin).
The ACE25X25SB has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for compact machinery. It uses a fixed TPU bumper at both ends to absorb impact, and with the -S magnet fitted, you can add CMSE or DMSE switches for position feedback. The port is M5x0.8, and the rod has a male thread for easy mounting.
