Airtac ACED Double-acting Compact Cylinder ACED125X70SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X70SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 70mm 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 ACED Double-acting Compact Cylinder ACED125X70SB
A double acting compact cylinder built to ISO 21287, the ACED125X70SB pushes a 125 mm bore through a 70 mm stroke with a 25 mm rod exiting BOTH covers. Because both strokes work on the rod-side area, output is identical in each direction: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, with a peak of 1201.3 kgf at 1.0 MPa. The through-rod resists rotation and side load and gives a symmetric mount, while the back-end rod can carry a sensor flag or a second tooling plate.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a fixed TPU bumper at each end. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy press fixtures and gantries where a full-length body will not fit. Plan on roughly 3534 N (about 360 kg of thrust) as the usable working force at 0.5 MPa rather than the full rating. The S in this model code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted anywhere along the body slots.

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 (Ø125mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 5890 N |
| 0.7 MPa | 8247 N |
| Max (@1.0 MPa) | 1201 kgf |
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 ACED125X70SB Is Used
Heavy press-fit and staking fixtures
The 5890.5 N both-ways output at 0.5 MPa presses bearings and bushings into housings on an automotive assembly line, with the 70 mm stroke clearing the part quickly between cycles.
Steel coil and pallet clamps
In a metalworking cell, the through-rod clamps a 300 kg coil fixture symmetrically from either side, and the short ISO 21287 body fits inside the guard where a profile cylinder cannot.
Position-verified stamping gantry
With the fitted -S magnet driving CMSE or DMSE switches, a stamping line gantry confirms both end positions of the 70 mm stroke before the next sheet is fed.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X70SB the Right Cylinder?
At this force class the 125 mm bore delivers 5890.5 N both ways at 0.5 MPa; step down to the 100 mm bore (3769.9 N) for lighter clamping or up from the 80 mm bore (2356.2 N) if 70 mm of stroke must move heavier tooling. The 70 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so it ships as a standard build. Remember that a plain double-rod cylinder drifts when air is lost - for a held load add a rod lock or pilot check valve. Mount with FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles on the ISO 21287 face, and order PT (blank) or G ports; the male rod thread (B code) on this unit bolts straight to external tooling.
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 ACED125X70SB FAQ
Yes - this is a double-rod cylinder, so a 25 mm rod exits both covers and every stroke uses the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in EITHER direction, peaking at 1201.3 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 70 mm stroke is within the 300 mm standard maximum for this bore.
It is an ISO 21287 compact cylinder: a roller-burnished, hard-anodized aluminium body with threaded aluminium covers, an S45C hard-chrome rod and a fixed TPU bumper at each end that decelerates the piston at stroke ends. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. The S in ACED125X70SB means the optional -S magnet is fitted, so CMSE / DMSE switches mount in the body slots; FA/FB flanges, LB foot and FTC brackets plus I/Y knuckles bolt to the standard ISO 21287 face.
