Airtac ACE Compact Cylinder ACE100X125
The AirTAC Airtac ACE Compact Cylinder ACE100X125 is a genuine double acting ISO 21287 compact air cylinder with a Ø100mm bore and 125mm stroke, 1/4" 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 ACE100X125
This AirTAC ACE100X125 is a double acting compact cylinder with a 100 mm bore and 125 mm stroke, delivering 3927 N of push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length cylinder will not.
With a 20 mm hard-chrome plated rod and a fixed TPU bumper at both ends, it handles speeds from 30 to 500 mm/s. For real work, plan for about 2356 N (0.6 times the push force) as a safe load at 0.5 MPa, which lifts roughly 240 kg vertically with a 2:1 safety margin. The optional -S magnet is not fitted here, so CMSE or DMSE sensors cannot be mounted unless you order the -S version.

Where the Airtac ACE Compact Cylinder ACE100X125 Is Used
CNC Machine Guard Door
Push open a sliding safety guard on a CNC milling machine. The 3927 N force at 0.5 MPa easily moves the 40 kg door, and the short body fits inside the machine frame without protruding into the work area.
Pallet Stop on Conveyor
Act as a pallet stop on a gravity conveyor in a packaging line. The 125 mm stroke lifts a steel stop pin to release pallets, with the fixed TPU bumper absorbing the impact of each pallet at speeds up to 500 mm/s.
Press Ram for Small Parts
Drive a small press ram for stamping metal brackets in a fabrication shop. The 5497.8 N push at 0.7 MPa provides enough force for light forming, and the compact body allows mounting in a tight press frame.
Is the Airtac ACE Compact Cylinder ACE100X125 the Right Cylinder?
For lighter duty, the ACE80X125 offers 2513 N push at 0.5 MPa, while the ACE125X125 provides 6135.9 N push at the same pressure. This 100 mm bore model suits medium-to-heavy automation tasks where a compact footprint is critical. Since the stroke is 125 mm, well under the 300 mm maximum standard, it is a stock item with no custom lead time. Mounting options like FA/FB flanges, LB foot, or CA/CB clevis bolt directly to the ISO 21287 face, and the 1/4" port matches standard air lines. Without the -S magnet, no sensor feedback is possible, so plan for limit switches or order the magnet option if you need position sensing.
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 ACE100X125 FAQ
At 0.5 MPa, push is 3927 N and pull is 3769.9 N. At 0.7 MPa, push is 5497.8 N and pull is 5277.9 N. The theoretical maximum force is 800.9 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).
The ACE is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder. This lets it fit into tight jigs and guards. It has a fixed TPU bumper at both ends, not an adjustable air cushion, and it does not lock or hold a load when air pressure is lost. For holding, use a rod lock or pilot check valve.
