Airtac ACE Compact Cylinder ACE50X225S
The AirTAC Airtac ACE Compact Cylinder ACE50X225S is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 225mm stroke, 1/8" 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 ACE50X225S
This AirTAC ACE50X225S is a double acting ISO 21287 compact cylinder with a 50 mm bore and a 225 mm stroke, delivering 981.7 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 guarding and compact jigs where a full-length cylinder would not.
With the optional -S magnet fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. For a 2:1 safety margin on vertical moves, plan to lift about 50 kg (half of the 100 kg theoretical lift at 0.5 MPa), and for horizontal work, budget around 589 N of usable force at 0.5 MPa.

Where the Airtac ACE Compact Cylinder ACE50X225S Is Used
Compact Jig Clamping
Use in a CNC fixture to clamp a 50 kg workpiece with a 2:1 safety margin at 0.5 MPa, fitting into a tight machine envelope where a longer cylinder would interfere.
Short-Stroke Transfer
Push a 40 kg box off a conveyor onto a chute in a packaging line, using the 225 mm stroke to clear the belt edge without needing a full-length actuator.
Guard Door Actuator
Open a small access door on a robotic cell, with the compact body mounted behind a safety guard and the magnet switch confirming the door position.
Is the Airtac ACE Compact Cylinder ACE50X225S the Right Cylinder?
Choose this 50 mm bore when you need a strong push in a short package; it provides 981.7 N push and 881.2 N pull at 0.5 MPa. For lighter duty, the 40 mm bore offers 628.3 N push, while stepping up to the 63 mm bore gives 1558.6 N push at the same pressure. The 225 mm stroke is within the 250 mm standard maximum for this bore, so it ships as a standard unit. Since the -S magnet is fitted, you can directly mount CMSE or DMSE switches; if you need to hold a load when air is removed, add a rod lock or pilot check valve because the TPU bumper does not lock the rod.
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 ACE50X225S FAQ
At 0.5 MPa, push is 981.7 N and pull is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. The port is 1/8 inch, and the rod has a female M10x1.5 thread.
The ACE body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in confined machine areas. It uses a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
