About the Airtac ACE Compact Cylinder ACE100X55SB
This AirTAC ACE100X55SB is a double acting compact cylinder that delivers 3927 N of push force at 0.5 MPa, making it a strong choice for medium-duty automation. Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames where a full-length cylinder would not.
With a 55 mm stroke and a 20 mm hard-chrome plated rod, this model includes the optional -S magnet, enabling CMSE or DMSE reed and solid-state switches for position sensing. For a safe vertical lift, plan for about 240 kg at 0.5 MPa with a 2:1 margin, based on the 3927 N push force, so you can match it to real part weights without over-engineering.

Where the Airtac ACE Compact Cylinder ACE100X55SB Is Used
Fixture Clamping
Use the 3927 N push force to clamp large workpieces in a CNC milling fixture, where the compact body fits under the table guard.
Carton Ejection
In a packaging line, this cylinder's 55 mm stroke pushes finished cartons off a conveyor onto a pallet, with the magnet tracking the piston for cycle confirmation.
Pallet Stops
Mount on a gravity conveyor to stop and release pallets; the 3769.9 N pull force retracts the stop quickly, and the short body keeps the profile low.
Is the Airtac ACE Compact Cylinder ACE100X55SB the Right Cylinder?
When sizing, compare this 100 mm bore unit against the 80 mm bore (2513 N push at 0.5 MPa) for lighter loads, or the 125 mm bore (6136 N push at 0.5 MPa) for heavier work. The 55 mm stroke is within the 300 mm standard maximum, so no custom order is needed. This model has a male rod thread (B code) and a 1/4" port, ready for standard fittings. Remember, this cylinder does not hold its position when air is lost; for a held load, add a rod lock or pilot check valve. The optional -S magnet is fitted here, so you can mount CMSE or DMSE switches directly on the body slots.
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 ACE100X55SB FAQ
At 0.5 MPa, the push force is 3927 N and the pull force 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. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with proof pressure at 1.5 MPa (215 psi).
The ACE100X55SB has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting space. It includes a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE switches for position sensing. The operating temperature range is -20 to +70 C, and speed is 30-500 mm/s.
