This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X100LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X100LB 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 ACP25X100LB
The AirTAC Airtac ACP Compact Cylinder ACP25X100LB is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X100LB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X100LB
The ACP25X100LB is a double acting DIN-standard compact cylinder with a 25 mm bore and 100 mm stroke, foot mounted via the LB code. 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. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding where a full-length body will not fit. Air supply is 0.15-1.0 MPa (22-145 psi), speed range 30-500 mm/s, and the hard-anodized aluminium body carries an S45C hard-chrome rod with a female M6x1.0 thread.
Plan on about 147 N of usable push at 0.5 MPa, roughly 15 kg of real work once you keep a margin below the 245.4 N rating; vertically that means it lifts about 12 kg with a 2:1 safety factor. This model is discontinued: the current-production drop-in is ACE25X100, which matches the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping. The fixed TPU bumper at each end only decelerates the piston; it never holds a load, so add a rod lock or pilot check valve if the rod must stay put when air is lost. No magnet is fitted - order the -S code if you need CMSE or DMSE switch sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X100LB (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 ACE25X100LB 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 ACP25X100LB Is Used
Bench-top press fixture
With 245.4 N push at 0.5 MPa, the 25 mm bore stakes small terminals or crimps wire ferrules on an electronics assembly bench, and the 100 mm stroke clears part loading by hand.
Packaging line pusher
Foot-mounted LB bodies bolt flat under a conveyor frame; the short body tucks between rollers to kick cartons off a belt at up to 500 mm/s.
Gantry part ejector
In a CNC cell, the compact body ejects finished aluminium brackets from a jig where an ISO 15552 profile cylinder would be about twice as long.
Replacing the Airtac ACP Compact Cylinder ACP25X100LB with the ACE25X100LB
At 25 mm bore this sits mid-range: step down to the 20 mm bore (157.1 N push at 0.5 MPa) for lighter clamping, or up to 32 mm (402.1 N) when the load needs nearly double the force. The 100 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. LB foot mounting suits horizontal runs bolted to a machine base; switch to FA/FB flange or CA/CB clevis if the fixture demands it. Remember the position-holding limit: without a rod lock or pilot check valve the piston drifts when pressure drops. For new designs, specify ACE25X100 instead - this ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE25X100LB
- ✓ 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 ACP25X100LB FAQ
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N. At 0.7 MPa push is 343.6 N and pull 288.6 N. 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, running on air filtered to 40 um at 30-500 mm/s.
Order ACE25X100, the current ISO 21287 successor: swap the P for an E and you keep the same 25 mm bore, 100 mm stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the older DIN-standard compact pattern. Also note the ACE only senses position if you order the -S magnet code for CMSE or DMSE switches.
