About the Airtac ACE Compact Cylinder ACE50X40SBH
This AirTAC ACE50X40SBH is a double acting compact cylinder delivering 981.7 N push and 881.2 N pull at 0.5 MPa, with a 1374.4 N push at 0.7 MPa. Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight automation cells.
For real-world work, plan on about 589 N (60 kg) of usable force at 0.5 MPa, so it can lift roughly 30 kg vertically with a 2:1 safety margin. The optional -S magnet is fitted here, enabling CMSE or DMSE reed and solid-state switches for position sensing, and the male rod thread simplifies coupling to tooling.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 ACE50X40SBH Is Used
Fixture Clamping
Clamp small parts in a CNC fixture with 981.7 N push at 0.5 MPa, using the compact body to fit under a workholding table.
Stop Gate
Actuate a stop gate on a packaging conveyor, where the 40 mm stroke and 881.2 N pull retract the gate quickly between cycles.
Press Plunger
Drive a plunger in a bench press for light stamping, relying on the 1374.4 N push at 0.7 MPa to form thin sheet metal.
Is the Airtac ACE Compact Cylinder ACE50X40SBH the Right Cylinder?
When sizing, compare this 50 mm bore to a 40 mm bore (628.3 N push) for lighter loads, or a 63 mm bore (1558.6 N push) if you need more margin. The 40 mm stroke suits short indexing moves, and the fixed TPU bumper handles speeds up to 500 mm/s without adjustment.
For mounting, choose FA/FB flange, LB foot, CA/CB clevis, or SDB pivot brackets that bolt to the ISO 21287 face. Since this model carries the -S magnet, you can add CMSE or DMSE sensors; without the -S code, no magnet is present, so order accordingly.
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 ACE50X40SBH FAQ
At 0.5 MPa, push is 981.7 N and pull is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi).
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, saving mounting length in guards and gantries. The fixed TPU bumper absorbs end-of-stroke energy, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
