About the Airtac ACE Compact Cylinder ACE20X5B
This AirTAC ACE20X5B is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 5 mm stroke, delivering 157.1 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 ideal for tight automation cells where space is at a premium.
The male rod thread (B code) simplifies attachment of custom tooling, while the hard-anodized aluminium body and S45C hard-chrome rod resist wear in high-cycle applications. At 0.5 MPa, a practical safe working load is about 94 N (roughly 9.6 kg) when you apply a 0.6 safety factor, so plan your real workload accordingly. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and since this model has no -S code, it has no magnet and cannot accept CMSE or DMSE sensors.

Where the Airtac ACE Compact Cylinder ACE20X5B Is Used
Precision Clamping Jig
Use the ACE20X5B to clamp small plastic parts in a CNC fixture, where its 5 mm stroke and 157.1 N push force securely hold components without excess travel.
Short-Stroke Alignment
In a packaging line, this cylinder can nudge cartons into alignment on a conveyor, using its compact body to fit between guide rails and its 117.8 N pull force to retract quickly.
Compact Tool Changer
Mount the ACE20X5B in a robotic end-of-arm tool to actuate a small gripper or pin, where the short stroke and male rod thread allow direct coupling to a custom bracket.
Is the Airtac ACE Compact Cylinder ACE20X5B the Right Cylinder?
For a 20 mm bore, the ACE20X5B offers a compact stroke of just 5 mm, ideal for short indexing or clamping tasks. If you need more force, consider the ACE25X5B with 245.4 N push at 0.5 MPa, or step down to the ACE16X5B with 100.5 N push for lighter duty. This model uses an M5x0.8 port and operates on filtered air (40 um) at 0.15-1.0 MPa (22-145 psi). Because it lacks the optional -S magnet, it cannot be used with CMSE or DMSE switches; order with -S if you need position sensing. The fixed TPU bumper does not hold a load, so use a rod lock or pilot check valve if you must maintain position when air pressure is lost.
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 ACE20X5B FAQ
At 0.5 MPa, the push force is 157.1 N and pull is 117.8 N. At 0.7 MPa, push rises to 219.9 N and pull to 164.9 N. The theoretical maximum force is 32 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, so its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight fixtures. However, this model has no -S code, meaning it has no magnet and cannot be used with CMSE or DMSE switches. The fixed TPU bumper absorbs end-of-stroke energy, but it does not provide adjustable cushioning or load holding.
