This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X50SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X50SB 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 ACP25X50SB
The AirTAC Airtac ACP Compact Cylinder ACP25X50SB is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X50SB
The ACP25X50SB is a double acting compact cylinder in the DIN-standard ACP series, with a 25 mm bore and 50 mm stroke pushing 245.4 N at 0.5 MPa. Its hard-anodized aluminium body and S45C hard-chrome rod keep the short ISO 21287-class build rigid, and the fixed TPU bumpers at both ends simply decelerate the piston. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for position feedback, and the B code gives a male rod thread.
Space is the real selling point: the short body saves roughly 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. For planning, treat about 147 N (0.6 of the 245.4 N push) as the usable working force at 0.5 MPa, which is roughly 15 kg of vertical lift with a 2:1 margin. Note that ACP25X50SB is discontinued; the current-production successor is ACE25X50, a drop-in in the same bore, stroke and force class.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X50SB (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 ACE25X50SB 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 ACP25X50SB Is Used
Small-parts ejection on assembly fixtures
The 245.4 N push at 0.5 MPa and 50 mm stroke suit knocking finished bushings or pins off a jig, with the -S magnet feeding a CMSE switch to confirm ejection each cycle.
Carton hold-down on a packing bench
About 15 kg of practical vertical force with a 2:1 margin is enough to clamp lightweight cartons flat while taping, and the short body fits under low bench frames.
Slide positioning in a compact gauge station
The male rod thread drives an I or Y knuckle on a short slide, while DMSE solid-state switches on the -S magnet report both end positions inside tight guard space.
Replacing the Airtac ACP Compact Cylinder ACP25X50SB with the ACE25X50SB
At 245.4 N push and 206.2 N pull on 0.5 MPa, the 25 mm bore sits between the 20 mm (157.1 N push) and 32 mm (402.1 N push) sizes; step up to 32 mm if your load needs more than about 147 N of working force. The 50 mm stroke is well inside the 150 mm standard limit for this bore, so no made-to-order stroke is involved. This version pairs the -S magnet with a male rod thread, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. Remember the rod drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put, and confirm ISO 21287 mounting dimensions before swapping to ACE25X50.
Replacement checklist
- ✓ Current-production ACE → ACE25X50SB
- ✓ 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 ACP25X50SB FAQ
Push is 245.4 N and pull 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 double acting with a 25 mm bore, 50 mm stroke, 10 mm rod, M5x0.8 ports, male rod thread, operating range 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s and temperature -20 to +70 C.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded zones. This model carries the optional -S magnet, so CMSE or DMSE switches can be clipped on for end-of-stroke signals. The model is discontinued; ACE25X50 is the current drop-in successor, so verify ISO 21287 mounting dimensions before ordering.
