This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X5B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X5B 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 ACP25X5B
The AirTAC Airtac ACP Compact Cylinder ACP25X5B is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X5B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X5B
The ACP25X5B is a double acting DIN-standard compact cylinder with a 25 mm bore and a very short 5 mm stroke, built around a hard-anodized aluminium body with an S45C hard-chrome piston rod. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa those figures rise to 343.6 N and 288.6 N, with a theoretical maximum of 50.1 kgf at 1.0 MPa. The B code gives a male rod thread, and the air ports are M5x0.8. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes this 5 mm stroke version ideal for clamping or ejecting inside tight fixture plates. Because roughly 60% of the push rating is a realistic working figure, plan for about 147 N of actual work at 0.5 MPa, which lifts about 15 kg vertically, or about 7 kg with a 2:1 margin. Note that this model is discontinued: the current-production replacement is the ACE25X5, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X5B (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 ACE25X5B 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 ACP25X5B Is Used
Fixture clamp ejection
The 245.4 N push at 0.5 MPa and 5 mm stroke suit short-travel workpiece ejection in CNC machining fixtures where a full-length cylinder will not fit.
Carton hold-down
A packaging line hold-down foot pressing flaps before taping, using the compact 25 mm bore body inside a tight guard frame.
Small part kick-off
Kicking small brackets off a conveyor stop with the 206.2 N pull stroke, with CMSE / DMSE switches available when the optional -S magnet is ordered.
Replacing the Airtac ACP Compact Cylinder ACP25X5B with the ACE25X5B
For a 5 mm stroke task, compare the 20 mm bore (157.1 N push at 0.5 MPa) if force is marginal, or step up to the 32 mm bore (402.1 N push at 0.5 MPa) for heavier clamping. The ACP25X5B does not hold position when air is lost - the piston drifts - so add a rod lock or pilot check valve for a held load. Mounting options include FA/FB flange, LB foot and CA/CB clevis, and the optional -S magnet code enables CMSE / DMSE switches; this unit has no magnet fitted. Order the ACE25X5 as the current drop-in successor and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE25X5B
- ✓ 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 ACP25X5B 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. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed range 30-500 mm/s. The rod is 10 mm with a male thread (B code) and the ports are M5x0.8.
This model is discontinued; the current-production replacement is the ACE25X5 (swap the P for an E), which matches the same 25 mm bore, 5 mm stroke and force class in the ISO 21287 family. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the standard face - confirm the ISO 21287 mounting dimensions before swapping, since the ACP was DIN-standard. The fixed TPU bumpers at both ends only decelerate the piston at stroke ends and never hold a load.
