Airtac ACE Compact Cylinder ACE50X70S
The AirTAC Airtac ACE Compact Cylinder ACE50X70S is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 70mm 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 ACE50X70S
This AirTAC ACE50X70S is a double acting compact cylinder that delivers 981.7 N of push force at 0.5 MPa, with a 70 mm stroke in a body about 50% shorter than an ISO 15552 profile cylinder. The hard-anodized aluminium body and S45C hard-chrome plated rod are built for repeated cycling in tight automation cells.
Because the -S magnet is fitted, you can mount CMSE or DMSE switches for reliable end-of-stroke sensing. For real work, plan on about 60 kg of usable vertical lift at 0.5 MPa, which is a practical 2:1 margin over the theoretical 981.7 N rating. The fixed TPU bumper at both ends absorbs energy, but it does not hold a load if air pressure is lost.

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 ACE50X70S Is Used
Fixture Clamping
Use the ACE50X70S to clamp sheet metal parts in a CNC drilling fixture, where its 981.7 N push holds the workpiece firmly and the short body fits under the spindle guard.
Package Stop Gate
Mount it as a stop gate on a packaging conveyor, extending to divert boxes up to 60 kg at 0.5 MPa, with the magnet triggering a DMSE switch to confirm the gate is up.
Gantry Pick-Up
On a small gantry robot, use the ACE50X70S to lift a 30 kg tooling plate vertically, relying on the 881.2 N pull force to retract it cleanly within the 30-500 mm/s speed range.
Is the Airtac ACE Compact Cylinder ACE50X70S the Right Cylinder?
For a lighter duty, consider the ACE40X70 with 628.3 N push, or step up to the ACE63X70 for 1558.6 N push at 0.5 MPa. The 1/8" port suits standard flow controls, and the female M10x1.5 rod thread accepts common clevis or knuckle fittings. Since this model has the magnet, order CMSE or DMSE sensors separately to confirm position. If you need to hold a vertical load when air is off, add a rod lock or pilot check valve, as the bumper is not a brake.
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 ACE50X70S 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 is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The ACE50X70S has a body that is about 50% shorter than an ISO 15552 profile cylinder, saving mounting length in confined jigs and guards. It uses a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet enables CMSE or DMSE sensors for position feedback. The hard-anodized aluminium body and hard-chrome rod ensure durability in continuous cycling.
