Airtac ACE Compact Cylinder ACE20X50S
The AirTAC Airtac ACE Compact Cylinder ACE20X50S is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 50mm stroke, M5×0.8 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 ACE20X50S
This AirTAC ACE20X50S is a double acting compact cylinder that uses air to both extend and retract its 10 mm rod. With a 20 mm bore it delivers a 157.1 N push force at 0.5 MPa, which is enough for light assembly tasks and small clamp actions.
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits inside tight machine guards and compact jigs. The optional -S magnet is fitted on this model, allowing CMSE or DMSE reed and solid-state switches to sense the piston position. For a real-world load, plan on about 9.6 kg of safe vertical lift at 0.5 MPa, using a 2:1 safety margin from the rated force.

Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 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 ACE20X50S Is Used
Small Part Clamping
Use in a benchtop fixture to clamp small electronic components during soldering or inspection, where the 157.1 N push force holds parts securely without damage.
Label Applicator
Drive a label tamp head in a packaging line, where the 50 mm stroke and compact body fit between conveyor rails and apply labels with consistent pressure.
Guard Door Interlock
Actuate a small safety guard latch on a machine, using the double acting retract to pull the latch clear and the 157.1 N push to re-engage it positively.
Is the Airtac ACE Compact Cylinder ACE20X50S the Right Cylinder?
For a lighter push, the 16 mm bore ACE16X50 provides 100.5 N at 0.5 MPa, while stepping up to the 25 mm bore ACE25X50 gives you 245.4 N at the same pressure. Choose this 20 mm version when you need a balance of compact size and moderate force for short-stroke operations. The M5x0.8 port suits small-bore air lines, and the female M6x1.0 rod thread accepts standard clevis or rod-end accessories. Since the magnet is fitted, you can directly mount CMSE or DMSE sensors for position feedback.
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 ACE20X50S FAQ
At 0.5 MPa, the push force is 157.1 N and the pull force is 117.8 N. At 0.7 MPa, push is 219.9 N and pull is 164.9 N. The theoretical maximum force is 32 kgf at 1.0 MPa. These figures are based on the 20 mm bore and assume clean, dry air.
The ACE20X50S follows ISO 21287, which makes the body about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces. It has a fixed TPU bumper at each end that absorbs impact at stroke limits, but it is not adjustable and does not lock or hold a load. For holding a position, use a separate rod lock or pilot check valve.
