This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X150SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X150SB 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 ACP25X150SB

About the Airtac ACP Compact Cylinder ACP25X150SB
The ACP25X150SB is a double acting compact cylinder in the DIN-standard ACP series, with a 25 mm bore pushing 245.4 N at 0.5 MPa (343.6 N at 0.7 MPa) over a 150 mm stroke. Its hard-anodized aluminium body with threaded aluminium covers and 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. This model carries the optional -S magnet code, so CMSE or DMSE reed and solid-state switches can be mounted for position feedback, and the B code gives a male rod thread.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this bore and stroke suit tight jigs, guarding and gantry axes. For sizing, plan on roughly 147 N of usable push at 0.5 MPa, which lifts about 12 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACE25X150, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X150SB (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 ACE25X150SB 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 ACP25X150SB Is Used
Small-part clamping fixture
Clamps aluminium brackets in a CNC secondary-operation jig, where the 245.4 N push at 0.5 MPa holds the part against a stop and the male rod thread takes a custom clamp tip.
Gantry pick station with position feedback
Because this unit carries the -S magnet, CMSE or DMSE switches confirm extend and retract on a 150 mm vertical lift of about 12 kg trays inside a compact machine frame.
Bottle-line reject pusher
Kicks off-spec cartons sideways on a packaging conveyor, using the short body that fits where an ISO 15552 profile cylinder would be about twice as long.
Replacing the Airtac ACP Compact Cylinder ACP25X150SB with the ACE25X150SB
At 25 mm bore the 245.4 N push at 0.5 MPa sits between the 20 mm bore (157.1 N) and the 32 mm bore (402.1 N), so step up to 32 mm if your tooling needs more than about 290 N of working force, or down to 20 mm for lighter clamping. The 150 mm stroke is the maximum standard stroke for this bore, so no made-to-order length is needed. If your valve centres or air drops, the rod will drift under load - add a rod lock or pilot check valve for held positions. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face, and the ACE25X150 is the current replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ACE25X150SB
- ✓ 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 ACP25X150SB FAQ
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa it pushes 343.6 N and pulls 288.6 N; the theoretical maximum is 50.1 kgf at 1.0 MPa. It runs double acting on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s with an M5x0.8 port and a 10 mm male-threaded rod. This model is discontinued - the current-production drop-in is the ACE25X150, same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before ordering.
The ACP25X150SB uses a hard-anodized aluminium body with threaded aluminium covers in the ISO 21287 short format, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder. Each end carries a fixed TPU bumper that simply decelerates the piston at the ends of travel - it is not adjustable and it never holds a load. FA/FB flange, LB foot and CA/CB clevis brackets mount on the standard face, and CMSE or DMSE switches work because this unit includes the optional -S magnet.
