About the Airtac ACE Compact Cylinder ACE20X45
This AirTAC ACE20X45 is a double acting compact cylinder built to ISO 21287, with a 20 mm bore and a 45 mm stroke. Its hard-anodized aluminium body and S45C hard-chrome rod deliver a 157.1 N push force at 0.5 MPa, while the fixed TPU bumper at each end absorbs impact without any adjustable settings.
At 0.5 MPa, this unit can safely lift about 9.6 kg vertically when you apply a 2:1 margin to the theoretical push force, making it a practical choice for light assembly tasks. The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a full-length unit will not. Since this model has no -S code, it has no magnet, meaning CMSE or DMSE sensors cannot be mounted unless you order the optional -S version.

Where the Airtac ACE Compact Cylinder ACE20X45 Is Used
Compact Jig Clamping
Use this ACE20X45 to clamp small plastic housings in an injection molding jig, where the 45 mm stroke and 157.1 N push at 0.5 MPa securely hold parts without taking up excessive space.
Light Conveyor Stop
In a packaging line, this cylinder can act as a stop gate for lightweight cartons moving at moderate speeds, leveraging its 117.8 N pull at 0.5 MPa to retract quickly and clear the path.
Test Fixture Actuator
For a benchtop durability test on small switches, this ACE20X45 provides repeatable 45 mm strokes at up to 500 mm/s, pushing a probe against the switch with a controlled force of about 157.1 N at 0.5 MPa.
Is the Airtac ACE Compact Cylinder ACE20X45 the Right Cylinder?
For a lighter duty application, consider the ACE16X45 with a 100.5 N push at 0.5 MPa, while the ACE25X45 offers a stronger 245.4 N push for heavier parts. This ACE20X45 suits medium-load tasks where space is limited, and the M5x0.8 port keeps plumbing simple. Remember that without the -S option, there is no built-in magnet for sensor feedback, so plan for external limit switches if position detection is needed. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face.
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 ACE20X45 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 rises to 219.9 N and pull to 164.9 N. The theoretical maximum force at 1.0 MPa is 32 kgf. These figures assume clean, filtered air and a properly aligned load.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight spaces like guard enclosures or multi-station tooling. The fixed TPU bumper at both ends absorbs end-of-stroke impacts, but it does not hold loads if air pressure is lost. For position holding, use a rod lock or pilot check valve. Also, this model has no magnet, so order the -S version if you need CMSE or DMSE sensors.
