This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X120S, the same code under the new prefix. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACP Compact Cylinder ACP100X120S
The AirTAC ACP Compact Cylinder ACP100X120S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 120mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X120S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X120S
The ACP100X120S is a double acting DIN-standard compact cylinder with a 100 mm bore and 120 mm stroke, delivering 3927 N push and 3681.6 N pull at 0.5 MPa, rising to 5497.8 N push at 0.7 MPa. Its hard-anodized aluminium body with an S45C hard-chrome rod is a short ISO 21287-class build that saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy gantries and press fixtures where a full-length body will not fit. The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the tube.
At this bore the theoretical peak is 800.9 kgf at 1.0 MPa, but a practical rule of thumb is to plan on about 60% of the 0.5 MPa push force, which works out near 240 kg of usable vertical lift - enough to raise a loaded pallet fixture or a die cart directly. Note the fixed TPU bumpers only decelerate the piston at each end; they never lock it, so if the valve is centred or air is lost the rod will drift under load - add a rod lock or pilot check valve for held positions. This model is discontinued: the current-production direct is ACE100X120, same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X120S (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | 5154 N |
| Max (@1.0 MPa) | 801 kgf | |
The ACE100X120S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP100X120S Is Used
Pallet-stamp lift station
With about 240 kg of practical vertical lift at 0.5 MPa, the 100 mm bore raises a loaded pallet under a stamping head in a warehouse line, with the 120 mm stroke clearing the die.
Press-fit fixture actuator
3927 N push at 0.5 MPa drives bearing or bushing press-fit operations on an assembly bench, and the short ISO 21287-class body fits inside the guard where a profile cylinder cannot.
Heavy gate diverter on a conveyor
The 5497.8 N push at 0.7 MPa swings a heavy sorting gate on a bottling conveyor, and the fitted -S magnet with a DMSE switch confirms gate position to the PLC.
Replacing the Airtac ACP Compact Cylinder ACP100X120S with the ACE100X120S
Size both ways before committing: if your load needs only about 982 N push at 0.5 MPa, a bore 50 unit is cheaper and lighter; if you need more than 3927 N, there is no larger ACP bore, so verify the ACE100X120 covers the duty. Stroke 120 mm sits well inside the 300 mm maximum standard stroke for bore 100, so no made-to-order build is needed. This unit carries the optional -S magnet for CMSE / DMSE switches, and the female M16x1.5 rod thread with a 1/4" PT port matches the standard fixture face. Remember it will not hold a load on lost air - pair it with a rod lock or pilot check valve where position must be kept. Order ACE100X120 as the current replacement and confirm ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE100X120S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP100X120S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa it pushes 5497.8 N and pulls 5154.2 N; theoretical maximum is 800.9 kgf at 1.0 MPa. It is a double acting compact cylinder, 100 mm bore with a 25 mm rod, 1/4" PT port, running on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-500 mm/s. The model is discontinued - ACE100X120 is the current replacement.
FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287-class face, so it drops into standard fixtures. The S code means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed or solid-state switches clamp onto the tube for end-of-stroke signals. The fixed TPU bumpers only soften the ends of travel and never hold the rod; use a rod lock or pilot check valve if the load must stay put.
