Airtac ACED Double-acting Compact Cylinder ACED125X55S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X55S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 55mm stroke, 1/4" air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED125X55S
The ACED125X55S is a double acting, double-rod compact cylinder built to ISO 21287: a 125 mm bore pushes and pulls with identical force because a 25 mm rod exits both covers and both strokes work on the rod-side area. At 0.5 MPa it delivers 5890.5 N in either direction, rising to 8246.7 N at 0.7 MPa. The hard-anodized aluminium body with an S45C hard-chrome plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with a fixed TPU bumper at each end and speeds of 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy-force class fits presses and gantries where a full-length body cannot. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted for end-of-stroke signalling. As a planning figure, about 3534 N (roughly 360 kg) is a comfortable working load at 0.5 MPa, and the rod-side force equates to lifting about 300 kg vertically with a 2:1 margin.

|---|---|
| 0.5 MPa | 5890 N |
| 0.7 MPa | 8247 N |

Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED125X55S Is Used
Baling and compacting stations
The 5890.5 N symmetric force at 0.5 MPa suits scrap balers and compacting fixtures where the 55 mm stroke compresses material between two opposing rods.
Pallet clamp and press fixtures
With about 360 kg of practical working force at 0.5 MPa, the through-rod clamps pallets or presses bearing housings in automotive assembly cells without a separate guide.
Counterbalanced lift columns
The rear rod acts as a counterbalance or sensor-flag carrier on vertical lift columns, while CMSE switches on the -S magnet confirm the 55 mm up and down positions.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X55S the Right Cylinder?
At 125 mm bore this is the top of the ACED range: 5890.5 N both ways at 0.5 MPa, roughly four times the 1458.1 N of a 63 mm bore. If your load needs under about 3000 N, the 100 mm bore (3769.9 N) is the smaller step; there is no larger ACED bore, so multi-cylinder layouts take over beyond 1201.3 kgf. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check valve if the 55 mm stroke must hold position. FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and the -S magnet in this model lets CMSE / DMSE switches report both end positions.
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 ACED Double-acting Compact Cylinder ACED125X55S FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, with a maximum of 1201.3 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, on air filtered to 40 um. The 1/4" port and M16x2.0 female rod thread match the 125 mm bore row of the ISO 21287 datasheet.
It is an ISO 21287 compact cylinder whose short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight press frames and gantries. A fixed TPU bumper at each end absorbs end-of-stroke energy; it does not lock or hold a load, so use a rod lock or pilot check where position must be kept. FA/FB flange, LB foot and FTC brackets mount on the standard face, and because this model carries the optional -S magnet, CMSE / DMSE switches can be clamped in the body slots for stroke signalling.
