Airtac ACE Compact Cylinder ACE20X90B
The AirTAC Airtac ACE Compact Cylinder ACE20X90B is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 90mm 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 ACE20X90B
This AirTAC ACE20X90B is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 90 mm stroke, delivering 157.1 N of push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, freeing up valuable space in tight machine frames and guarding. The male rod thread (B code) simplifies direct attachment of custom tooling without needing a rod-end adapter.
For real-world sizing, plan for roughly 94 N of usable work at 0.5 MPa, which translates to lifting about 9.6 kg vertically with a 2:1 safety margin. The fixed TPU bumper at both ends absorbs impact energy, but it does not lock the rod in place; if you need to hold a load when air pressure drops, add an external rod lock or pilot check valve. This version has no magnet, so CMSE or DMSE proximity switches cannot be fitted unless you order the optional -S code.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE20X90B Is Used
PCB Depanelization Press
Use the 157.1 N push force to gently snap scored PCB panels apart on a benchtop fixture, where the short body fits under a safety light curtain and the 90 mm stroke clears the board edge.
Blister Pack Ejector
Mount this cylinder in a blister packaging line to push formed trays out of a die. The 117.8 N retract force reliably pulls the pusher back, while the compact length keeps the station within the machine guard.
Lab Sample Dispenser
In a diagnostic instrument, this cylinder actuates a syringe plunger to dispense reagents. The male rod thread connects directly to a Luer lock adapter, and the fixed TPU bumper prevents hard stops that could shatter glass vials.
Is the Airtac ACE Compact Cylinder ACE20X90B the Right Cylinder?
When sizing this ACE20X90B, compare it against the smaller ACE16X90, which offers 100.5 N push, or step up to the ACE25X90 for 245.4 N push at the same 0.5 MPa. For a 90 mm stroke, the 20 mm bore is a balanced choice for light assembly tasks, but if your application involves side loads or requires precise positioning, consider a larger bore or a guided variant like the TACE non-rotating model. The M5x0.8 port suits small-bore tubing and fittings common in compact automation cells.
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 ACE20X90B 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 is 219.9 N and pull is 164.9 N. The theoretical maximum 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).
No, this ACE20X90B does not have a magnet, so CMSE or DMSE reed switches cannot be attached. To use sensors, you must order the model with the optional -S suffix, which adds the magnet for switch detection. The cylinder itself has a fixed TPU bumper at both ends to absorb impact, not an adjustable air cushion.
