Airtac ACE Compact Cylinder ACE50X35
The AirTAC Airtac ACE Compact Cylinder ACE50X35 is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 35mm 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 ACE50X35
This AirTAC ACE50X35 is a double acting compact cylinder that extends and retracts its 16 mm hard-chrome rod with air pressure on both strokes. At 0.5 MPa it delivers 981.7 N of push force and 881.2 N of pull, so it suits medium-duty clamping and transfer tasks in tight spaces.
The ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, which helps when fitting into guarded machine zones or compact gantries. The hard-anodized aluminium body and S45C rod resist wear, and the fixed TPU bumper at each end softens impact. For a safe working load, plan around 589 N (about 60 kg) at 0.5 MPa rather than the full rating, leaving a margin for real-world friction and speed.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACE50X35 Is Used
Fixture Clamping
Use in a CNC fixture to clamp a 50 mm thick aluminum plate during drilling. The 981.7 N push holds the part firmly, and the short body fits between the vise jaws and the machine table.
Package Stop Gate
Mount on a conveyor line to stop cardboard boxes weighing up to 40 kg. The 35 mm stroke lifts a stop finger quickly, and the fixed TPU bumper handles repeated cycles at 300 mm/s without damage.
Carton Tucking
In a packaging cell, push a folded carton flap into place before sealing. The 881.2 N pull retracts the rod smoothly, and the compact body fits behind the sealing head where space is tight.
Is the Airtac ACE Compact Cylinder ACE50X35 the Right Cylinder?
For lighter work, the ACE40X35 offers 628.3 N push at 0.5 MPa, while the ACE63X35 steps up to 1558.6 N push. This 50 mm bore with a 35 mm stroke fits between those options, giving a compact envelope with a solid force reserve. Since this model has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted; order the -S variant if you need position sensing. Mounting options like FA/FB flange, LB foot, or CA/CB clevis bolt to the ISO 21287 face, and the female M10x1.5 rod thread accepts standard attachments.
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 ACE50X35 FAQ
At 0.5 MPa, push is 981.7 N and pull 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 apply to this 50 mm bore with a 16 mm rod.
No, this specific ACE50X35 has no magnet because the -S code was not ordered. Without the optional -S magnet, CMSE or DMSE switches cannot detect the piston position. If you need sensing, order the ACE50X35S variant. The cylinder has a fixed TPU bumper at both ends, not an adjustable air cushion.
