This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X90SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X90SB 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 ACP25X90SB
The AirTAC Airtac ACP Compact Cylinder ACP25X90SB is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X90SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X90SB
A double acting DIN-standard compact cylinder, the ACP25X90SB drives a 25 mm bore through a 90 mm stroke with a male threaded rod (the B code) and a fixed TPU bumper at each end. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N, rising to 343.6 N push at 0.7 MPa, with a theoretical ceiling of 50.1 kgf at 1.0 MPa. Air supply runs 0.15-1.0 MPa (22-145 psi) and rod speed 30-500 mm/s.
The hard-anodized aluminium body with S45C hard-chrome rod is an ISO 21287 class short build, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. Because the -S magnet is fitted on this model, CMSE or DMSE reed and solid-state switches mount directly for end-of-stroke sensing. Plan on about 147 N (roughly 15 kg of vertical lift) of real work at 0.5 MPa rather than the full rating. Note this model is discontinued: the current-production drop-in is ACE25X90, same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X90SB (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 ACE25X90SB 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 ACP25X90SB Is Used
Fixture clamping on CNC pallets
The 245.4 N push at 0.5 MPa clamps aluminium brackets in machining fixtures, and the 90 mm stroke clears part loading in a short envelope.
Position-verified ejector on assembly lines
With the -S magnet fitted, CMSE or DMSE switches confirm the eject stroke on small electronics assemblies before the next cycle starts.
Carton push-off in compact packaging heads
The short ISO 21287 class body fits inside packaging machine frames where a full-length profile cylinder cannot reach, pushing cartons at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP25X90SB with the ACE25X90SB
For a 90 mm stroke in the 245 N class, bore 25 is the right pick; step down to bore 20 (157.1 N push at 0.5 MPa) for lighter clamping, or up to bore 32 (402.1 N) when the part weight grows. Remember the plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. The male rod thread suits I/Y rod knuckles, and FA/FB flange, LB foot or CA/CB clevis mountings bolt to the same face. Since ACP25X90SB is discontinued, order ACE25X90 as the current equivalent and verify the ISO 21287 hole pattern against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACE25X90SB
- ✓ 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 ACP25X90SB FAQ
At 0.5 MPa the 25 mm bore delivers 245.4 N push and 206.2 N pull; at 0.7 MPa that rises to 343.6 N push and 288.6 N pull. The theoretical maximum is 50.1 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and rod speed spans 30-500 mm/s. For real work, budget about 147 N - roughly 15 kg of vertical lift.
No - the ACP family is discontinued. The current-production replacement is ACE25X90, an ISO 21287 compact cylinder in the same bore, stroke and force class with a matching short body and mounting family. Confirm the ISO 21287 mounting dimensions against your existing fixture before swapping, since the ACP was built to the older DIN standard.
