About the Airtac ACE Compact Cylinder ACE16X20S
This AirTAC ACE16X20S is a double acting ISO 21287 compact cylinder that extends and retracts its 8 mm rod with air pressure. It delivers a 100.5 N push and 75.4 N pull at 0.5 MPa, with a theoretical maximum of 20.5 kgf at 1.0 MPa, making it a solid choice for light automation tasks.
Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine guards and compact jigs. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. For a safe working load, plan for about 60 N of real work at 0.5 MPa, which is roughly 6 kg of vertical lift with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE16X20S Is Used
Compact Jig Clamping
Use in a small pneumatic jig to hold a plastic housing during a drilling operation, where the 20 mm stroke and 100.5 N push provide enough force to secure the part without taking up much space.
Label Applicator
Drive a label applicator head in a packaging line, using the 75.4 N pull to retract the rod quickly after each label is placed, keeping the cycle time under 500 mm/s.
Guard Door Interlock
Activate a small safety interlock on a machine guard, where the compact body fits behind a panel and the 20 mm stroke moves a locking pin into place, with the optional -S magnet confirming the position via a CMSE switch.
Is the Airtac ACE Compact Cylinder ACE16X20S the Right Cylinder?
When sizing, consider the ACE12X20 for a lighter 56.5 N push at 0.5 MPa, or step up to the ACE20X20 for a stronger 157.1 N push. This 16 mm bore model with a 20 mm stroke suits short, repetitive movements where space is limited. The M5x0.8 port is standard for this bore, and the female M4x0.7 rod thread allows direct attachment. Since the magnet is fitted, you can add CMSE or DMSE switches for reliable end-of-stroke detection.
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 ACE16X20S FAQ
At 0.5 MPa, the push force is 100.5 N and the pull force is 75.4 N. At 0.7 MPa, push is 140.7 N and pull is 105.6 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s.
The ACE16X20S has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits into tight spaces. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet allows you to mount CMSE or DMSE switches for position sensing.
