Airtac ACE Compact Cylinder ACE50X40S
The AirTAC Airtac ACE Compact Cylinder ACE50X40S is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 40mm 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 ACE50X40S
This AirTAC ACE50X40S is a double acting compact cylinder that delivers 981.7 N of push force at 0.5 MPa, making it a solid choice for mid-range automation tasks. Its ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length unit will not.
With the optional -S magnet already fitted, you can mount CMSE or DMSE reed and solid-state switches for reliable position sensing. For a real-world load, plan on about 60 kg of safe vertical lifting at 0.5 MPa (981.7 N divided by 9.81, then halved for a 2:1 safety margin), so match it to parts that weigh up to that figure.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE50X40S Is Used
Jig Clamping
Use in a CNC fixture to clamp a 50 mm wide workpiece with 981.7 N force, where the short body fits under the spindle guard.
Parcel Stop Gate
Actuate a stop gate on a parcel conveyor, lifting a 5 kg flap with a 40 mm stroke to divert boxes at speeds up to 500 mm/s.
Press Ram
Drive a small arbor press ram for inserting bushings into aluminum housings, relying on the 881.2 N pull force for the return stroke.
Is the Airtac ACE Compact Cylinder ACE50X40S the Right Cylinder?
When sizing, consider the ACE40X25 (628.3 N push at 0.5 MPa) if you need a lighter, more compact option, or step up to the ACE63X40 (1558.6 N push at 0.5 MPa) for higher force in the same envelope. This 50 mm bore with a 40 mm stroke suits short-stroke clamping, pressing, and transfer applications where space is at a premium. Since the magnet is fitted, order CMSE or DMSE switches separately to confirm position. Remember, this cylinder does not hold its load if air pressure is lost - use a rod lock or pilot check valve for safety-critical 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 ACE50X40S 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. Operating pressure range is 0.15-1.0 MPa (22-145 psi).
The hard-anodized aluminum body is about 50% shorter than an ISO 15552 profile cylinder, so it saves mounting length in confined jigs and guards. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE switches for position sensing.
