Airtac ACE Compact Cylinder ACE16X25B
The AirTAC Airtac ACE Compact Cylinder ACE16X25B is a genuine double acting ISO 21287 compact air cylinder with a Ø16mm bore and 25mm 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 ACE16X25B
This AirTAC ACE16X25B is a double acting ISO 21287 compact cylinder with a 16 mm bore and a 25 mm stroke, delivering 100.5 N of push force at 0.5 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it a fit for tight automation cells where space is at a premium.
With a male rod thread (B code) and a hard-anodized aluminium body over an S45C hard-chrome rod, this unit is built for repeated cycling. The fixed TPU bumper at both ends absorbs end-of-stroke energy, but it does not lock or hold a load; for a held position, use a rod lock or pilot check valve. As a practical rule, plan for about 60 N of real work at 0.5 MPa, which lifts roughly 6 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE16X25B Is Used
Small Part Clamping
Use in a fixture to clamp small plastic or aluminum parts during drilling or light milling, where the 100.5 N push force holds components securely without distortion.
Label Applicator
Drive a label applicator head in a packaging line, cycling at moderate speeds to press labels onto small boxes or bottles, with the compact body fitting under existing guards.
Test Probe Actuator
Actuate a spring-loaded test probe in an electronics bench fixture, using the 25 mm stroke to make contact with circuit boards, and the male rod thread for easy probe attachment.
Is the Airtac ACE Compact Cylinder ACE16X25B the Right Cylinder?
For lighter duty, the ACE12X25 offers 56.5 N push at 0.5 MPa, while stepping up to the ACE20X25 gives you 157.1 N push at the same pressure. This ACE16X25B sits in between, ideal for small part clamping or light actuation where a compact footprint is key. 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. The M5x0.8 port suits 4 mm or 6 mm tubing with the right fittings.
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 ACE16X25B 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), with a proof pressure of 1.5 MPa (215 psi).
Yes, it is an ISO 21287 compact cylinder, about 50% shorter than an ISO 15552 profile cylinder, saving space in tight jigs. However, this model (without the -S code) has no magnet, so you cannot mount CMSE or DMSE sensors. Order the -S variant if you need position sensing. The fixed TPU bumper at both ends absorbs end-of-stroke impact but does not act as a brake.
