About the Airtac ACE Compact Cylinder ACE20X30SBH
This AirTAC ACE20X30SBH is a double acting compact cylinder built to ISO 21287, with a 20 mm bore and a 30 mm stroke that suits short-travel automation tasks. Its hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at each end absorbs impact without the need for adjustment.
At 0.5 MPa the push force is 157.1 N and the pull is 117.8 N, so plan for about 94 N of real work using a 0.6 safety factor, or roughly 9.6 kg of vertical lift with a 2:1 margin. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it a fit for tight fixtures where space is limited. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for position sensing.

Where the Airtac ACE Compact Cylinder ACE20X30SBH Is Used
Fixture Clamping
Use the ACE20X30SBH to clamp small plastic housings in a CNC fixture, where the 30 mm stroke and 157.1 N push at 0.5 MPa hold parts firmly without taking up jig space.
Part Ejection
On a packaging conveyor, this cylinder can push finished components off a guide rail at 30 mm stroke, with the compact body fitting under the belt line and the magnet enabling position feedback.
Guard Door Interlock
In a light assembly machine, the ACE20X30SBH actuates a small safety guard door, using its 157.1 N push to move the door and the optional -S magnet to confirm closure via a CMSE switch.
Is the Airtac ACE Compact Cylinder ACE20X30SBH the Right Cylinder?
For a 20 mm bore, the ACE20X30SBH delivers 157.1 N push at 0.5 MPa, which is a good middle ground between the lighter ACE16 (100.5 N) and the stronger ACE25 (245.4 N). If your load is under 9 kg and you need a compact package, this bore works; for heavier parts, step up to the 25 mm bore. The male rod thread (B) simplifies mounting with rod-end accessories, and the M5x0.8 port is standard for this bore size. Since the magnet is fitted, you can add CMSE sensors for end-of-stroke detection, but remember this cylinder does not hold position when air is removed - use a rod lock or pilot check valve for load holding.
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 ACE20X30SBH FAQ
At 0.5 MPa, the push force is 157.1 N and the 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 at 1.0 MPa is 32 kgf. These are based on a 20 mm bore with a 10 mm rod.
No, the magnet is optional. The 'S' in the model code ACE20X30SBH indicates that this specific unit has the optional -S magnet fitted, which allows mounting of CMSE or DMSE reed and solid-state switches. Without the -S code, no magnet is present, so sensors cannot be used.
