Airtac ACE Compact Cylinder ACE50X45
The AirTAC Airtac ACE Compact Cylinder ACE50X45 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 ACE50X45
This AirTAC ACE50X45 is a double acting compact cylinder built to ISO 21287, with a 50 mm bore and 45 mm stroke. It delivers 981.7 N of push force at 0.5 MPa, so it can handle moderate pushing tasks in tight spaces.
Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for cramped fixtures. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a safe working load, plan for about 589 N (60 kg) of real work at 0.5 MPa, not the full rating.

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 ACE50X45 Is Used
Fixture Clamping
Use in a jig to clamp sheet metal parts during drilling or welding. The 981.7 N push holds parts firmly, and the compact body fits under a workbench guard.
Package Stop Gate
Mount on a conveyor line to stop or divert boxes weighing up to 60 kg. The 45 mm stroke is enough to extend a stop finger, and the short body saves space between rollers.
Press Guard Interlock
Actuate a safety guard on a small press. The double acting action retracts the guard positively, and the fixed TPU bumper prevents noise at high cycle rates up to 500 mm/s.
Is the Airtac ACE Compact Cylinder ACE50X45 the Right Cylinder?
For a lighter duty, consider the ACE40X45 with 628.3 N push at 0.5 MPa, or step up to the ACE63X45 for 1558.6 N push. This model uses a 1/8" port and has a female M10x1.5 rod thread. It does not include a magnet, so order the -S code if you need to mount CMSE or DMSE sensors. Mounting options like FA/FB flange, LB foot, or CA/CB clevis bolt directly to 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 ACE50X45 FAQ
At 0.5 MPa, it pushes with 981.7 N and pulls with 881.2 N. At 0.7 MPa, it pushes with 1374.4 N and pulls with 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. These figures are for the double acting cylinder with a 50 mm bore and 16 mm rod.
Yes, it is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends, not an adjustable cushion, and operates at speeds from 30 to 500 mm/s. The port is 1/8" and the rod thread is M10x1.5.
