This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X15SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X15SB 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 ACP25X15SB
The AirTAC Airtac ACP Compact Cylinder ACP25X15SB is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X15SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X15SB
A double acting compact cylinder in the DIN-standard ACP series, the ACP25X15SB pairs a 25 mm bore with a 15 mm stroke and a male-threaded 10 mm rod. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N, rising to 343.6 N on the extend stroke at 0.7 MPa. The hard-anodized aluminium body with an S45C hard-chrome rod runs on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a fixed TPU bumper at each end.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. Because the -S magnet is fitted on this model, CMSE or DMSE reed and solid-state switches can be clamped straight onto the tube for end-of-stroke sensing. As a working rule, plan on roughly 147 N (about 15 kgf) of usable push at 0.5 MPa, enough to lift around 12 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACE25X15, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X15SB (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 ACE25X15SB 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 ACP25X15SB Is Used
Small-part press fitting
With 245.4 N of push at 0.5 MPa, the 15 mm stroke suits pressing dowel pins or bearings into aluminium housings on an electronics assembly bench.
Carton kick-off on packing lines
The short body and quick 15 mm stroke make it a fit for nudging cartons or blisters off a conveyor lane where a full-length cylinder will not fit.
Position-verified clamping
Because the -S magnet is fitted, CMSE or DMSE switches confirm clamp-open and clamp-closed on a fixture before the robot cycle is allowed to start.
Replacing the Airtac ACP Compact Cylinder ACP25X15SB with the ACE25X15SB
At 25 mm bore this sits mid-range: a 20 mm bore gives 157.1 N push at 0.5 MPa for lighter clamping, while a 32 mm bore reaches 402.1 N if your fixture grows. The 15 mm stroke is well inside the 150 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. Remember the rod drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the same face family as the ACE25X15 replacement, and the male rod thread (B code) suits I/Y rod knuckles.
Replacement checklist
- ✓ Current-production ACE → ACE25X15SB
- ✓ 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 ACP25X15SB FAQ
Push is 245.4 N and pull is 206.2 N at 0.5 MPa; at 0.7 MPa push rises to 343.6 N and pull to 288.6 N, with a theoretical maximum of 50.1 kgf at 1.0 MPa. It is a double acting compact cylinder, 25 mm bore, 15 mm stroke, 10 mm rod with male thread, M5x0.8 ports, operating on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a fixed TPU bumper at both ends. The model is discontinued; the ACE25X15 is the current replacement.
Yes - the S in the model code means the optional -S magnet is fitted on this unit, so CMSE reed or DMSE solid-state switches clamp directly onto the tube for end-of-stroke signals. Without the -S code there is no magnet in the piston. Also note the bumper only decelerates the piston at the ends; it never holds a load, so use a rod lock or pilot check valve where position must be kept on air loss.
