This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X100S in place of this model. 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 ACP25X100S
The AirTAC Airtac ACP Compact Cylinder ACP25X100S is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X100S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X100S
A double acting compact cylinder with a 25 mm bore and 100 mm stroke, the ACP25X100S pushes 245.4 N and pulls 206.2 N at 0.5 MPa (343.6 N / 288.6 N at 0.7 MPa). The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing. Its hard-anodized aluminium body and S45C hard-chrome rod run on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a fixed TPU bumper at each end.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guard rails. Practical sizing: keep real work to about 147 N (roughly 0.6 of the push rating), which corresponds to lifting about 12 kg vertically with a 2:1 margin. Note that this model is discontinued; the current-production drop-in is ACE25X100, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X100S (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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
The ACE25X100S 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 ACP25X100S Is Used
Carton push-off on case packers
Ejects filled cartons from a forming station; the 245.4 N push at 0.5 MPa clears a 10 kg pack easily and the 100 mm stroke matches typical lane widths.
Position-verified clamp on an assembly jig
With the fitted magnet and a DMSE switch, the PLC confirms the clamp is fully advanced before the press cycle starts.
Small part press-fit station
Seats bushings into plastic housings on an electronics line; about 147 N of usable force at 0.5 MPa suits light interference fits.
Replacing the Airtac ACP Compact Cylinder ACP25X100S with the ACE25X100S
At 245.4 N push at 0.5 MPa this 25 mm bore sits between the 20 mm (157.1 N) and 32 mm (402.1 N) sizes; step up to 32 mm if your load needs more than about 147 N of usable force. The 100 mm stroke is within the 150 mm standard range for this bore. This unit carries the optional -S magnet, so CMSE / DMSE switches work out of the box; FA/FB flange, LB foot and CA/CB clevis mounts are available. A plain cylinder drifts when air is lost, so add a rod lock or pilot check valve for held loads. Replacement: ACE25X100.
Replacement checklist
- ✓ Current-production ACE → ACE25X100S
- ✓ 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 ACP25X100S FAQ
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa, 343.6 N push and 288.6 N pull. Theoretical maximum is 50.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um. Plan real work around 147 N and about 12 kg of vertical lift for margin.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends, M6x1.0 female rod thread and M5x0.8 ports. FA/FB flange, LB foot and CA/CB clevis mount on the standard face. The ACP25X100S is discontinued; the current drop-in is ACE25X100 in the same bore, stroke and force class - confirm ISO 21287 mounting dimensions before ordering.
