Airtac ACE Compact Cylinder ACE50X40
The AirTAC Airtac ACE Compact Cylinder ACE50X40 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 ACE50X40
This AirTAC ACE50X40 is a double acting compact cylinder that uses air to both extend and retract the 16 mm rod. With a 50 mm bore it delivers 981.7 N of push force and 881.2 N of pull force at 0.5 MPa, making it a solid mid-range workhorse for automated assembly.
Its ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, so it fits into tight guarding and gantries. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper absorbs end-of-stroke impact. For a real-world load, plan on about 60 kg of safe vertical lift at 0.5 MPa, which is roughly 0.6 times the push force divided by gravity.

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 ACE50X40 Is Used
Jig Clamping
Use the 981.7 N push force to clamp sheet metal parts in a welding jig, holding them firmly during spot welding without taking up excessive space in the fixture.
Sorting Gate
Actuate a diverter gate on a packaging conveyor line, where the 40 mm stroke is enough to redirect boxes weighing up to 60 kg at line speeds of 0.5 m/s.
Press Plunger
Drive a small plunger in a bench-top press for inserting brass bushings into aluminum housings, relying on the 1374.4 N push at 0.7 MPa for consistent seating force.
Is the Airtac ACE Compact Cylinder ACE50X40 the Right Cylinder?
For lighter duty, the ACE40X40 offers 628.3 N push at 0.5 MPa, while the ACE63X40 steps up to 1558.6 N push. This ACE50X40 sits between them, giving you a balanced force-to-size ratio for medium-weight clamping or pressing tasks. The 1/8" port suits standard flow rates for speeds up to 500 mm/s.
This model has no magnet, so it cannot work with CMSE or DMSE sensors unless you order the optional -S version. Mounting options like FA/FB flange, LB foot, or CA/CB clevis bolt directly to the ISO 21287 face, making integration into existing fixtures straightforward.
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 ACE50X40 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 rises to 1374.4 N and pull to 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. These figures assume clean, dry air within the 0.15-1.0 MPa operating range.
No. This model has no magnet, so CMSE or DMSE switches cannot detect the piston position. You must order the ACE50X40S version, which includes the optional -S magnet, to use reed or solid-state sensors. The cylinder itself is compact, saving about 50% mounting length versus an ISO 15552 profile cylinder, and uses fixed TPU bumpers at both ends.
