About the Airtac ACE Compact Cylinder ACE100X125B
This AirTAC ACE100X125B is a compact double-acting cylinder that uses air to extend and retract its 20 mm hard-chrome rod. Its 100 mm bore delivers 3927 N of push force at 0.5 MPa, making it a strong choice for medium-duty automation where space is tight.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into compact jigs and guarded cells. With a male rod thread (B code) and a 1/4" PT port, it connects directly to standard fittings. This unit has no magnet, so it cannot use CMSE or DMSE sensors unless you order the optional -S version. For a safe working load, plan for about 2356 N (0.6 x 3927 N) at 0.5 MPa, which lifts roughly 240 kg vertically with a 2:1 margin.

Where the Airtac ACE Compact Cylinder ACE100X125B Is Used
Press Fit Station
Use the 3927 N push at 0.5 MPa to press bushings or bearings into housings on a workbench fixture, where the compact body fits under a guarding hood.
Parcel Pusher
Mount this cylinder sideways on a conveyor frame to divert boxes weighing up to 200 kg onto a sorting lane, using the 125 mm stroke for a quick shove.
Clamp for Welding Jig
Hold sheet metal parts firmly against a welding fixture with the 3769.9 N pull force at 0.5 MPa, while the short body leaves room for torch access.
Is the Airtac ACE Compact Cylinder ACE100X125B the Right Cylinder?
Choose this 100 mm bore cylinder when you need a strong push in a short envelope. It delivers 3927 N push and 3769.9 N pull at 0.5 MPa, while a smaller 80 mm bore gives 2513.3 N push and a larger 125 mm bore gives 6135.9 N push. The 125 mm stroke is well within the 300 mm maximum standard stroke for this bore.
Since this model has no magnet, it cannot trigger proximity sensors. If you need position sensing, order the ACE100X125SB version with the optional -S magnet. The male rod thread simplifies mounting with rod clevis or knuckle attachments. Remember, this cylinder does not hold its position when air pressure is lost; use a rod lock or pilot check valve for load holding.
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 ACE100X125B FAQ
At 0.5 MPa, push force is 3927 N and 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. This is a double-acting cylinder, so air powers both extension and retraction.
The ACE100X125B follows ISO 21287, a compact standard that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends to absorb impact, but it is not adjustable. This model has no magnet, so it cannot work with CMSE or DMSE switches; you must order the -S version to add the optional magnet for sensor detection.
