Airtac ACE Compact Cylinder ACE50X45B
The AirTAC Airtac ACE Compact Cylinder ACE50X45B is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 45mm stroke, 1/8" 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 ACE50X45B
This AirTAC ACE50X45B is a double acting ISO 21287 compact cylinder with a 50 mm bore and 45 mm stroke, delivering 981.7 N push and 881.2 N pull at 0.5 MPa. The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames where a full-length unit will not.
With a male rod thread (B code) and no optional -S magnet, this unit cannot accept CMSE or DMSE sensors unless you order the -S variant. For a real-world load, plan on about 60 kg of safe vertical lift at 0.5 MPa (981.7 N divided by 9.81, then halved for a 2:1 margin), making it a solid choice for light assembly presses and clamping fixtures.

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 ACE50X45B Is Used
Light Assembly Press
Use the 981.7 N push at 0.5 MPa to press small bushings or bearings into aluminum housings on a workbench fixture, where the short body keeps the tool low and accessible.
Conveyor Stop Gate
Mount this cylinder with an LB foot bracket to raise a stop gate on a packaging line, cycling at 30-500 mm/s to sort boxes without taking up extra conveyor-side space.
Pallet Clamp
In a warehouse transfer station, use the 881.2 N pull at 0.5 MPa to clamp a pallet against a guide rail during automated wrapping, thanks to the compact body fitting under the conveyor frame.
Is the Airtac ACE Compact Cylinder ACE50X45B the Right Cylinder?
For a lighter duty, the ACE40X45 offers 628.3 N push at 0.5 MPa, while the ACE63X45 steps up to 1558.6 N push for heavier parts. Since this is a plain double acting cylinder, it will not hold its position if air pressure is lost or the valve is centered - add a rod lock or pilot check valve for load holding. The 1/8" port and male rod thread suit standard fittings, and you can add FA/FB flange, LB foot, or CA/CB clevis mounts to match your fixture.
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 ACE50X45B 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), with a proof pressure of 1.5 MPa (215 psi).
No, the ACE50X45B as ordered has no magnet because the -S code is absent. To use CMSE or DMSE reed or solid-state switches, you must order the ACE50X45BS variant with the optional magnet. The fixed TPU bumper at both ends absorbs end-of-stroke energy but does not lock or hold a load.
