This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X175S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X175S 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 ACP20X175S
The AirTAC Airtac ACP Compact Cylinder ACP20X175S is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 175mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X175S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X175S
A double acting compact cylinder in the DIN-standard ACP series, the ACP20X175S pairs a 20 mm bore with a 175 mm stroke and ships with the optional -S magnet already fitted, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those figures rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The 175 mm stroke is longer than the 100 mm standard limit for this bore, so it is a made-to-order build. Note this model is discontinued - the current-production replacement is ACE20X175.
The hard-anodized aluminium body with threaded aluminium covers and an S45C hard-chrome rod keeps the short ISO 21287-class body roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, which is why it slots into slim sliding doors and pick stations. For sizing, treat about 94 N (roughly 60% of the push rating) as the usable force at 0.5 MPa, and expect it to lift about 8 kg vertically with a 2:1 margin. A fixed TPU bumper at each end decelerates the piston, and speed runs 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X175S (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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
The ACE20X175S 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 ACP20X175S Is Used
Bottle rejection gates
The 175 mm reach swings a pusher arm across a bottling conveyor lane, with 157.1 N of push at 0.5 MPa clearing a rejected bottle in one cycle and the fitted magnet confirming the retracted position.
Small-parts lift tables
Raising fixtures of about 8 kg on an electronics assembly bench, where the 20 mm bore gives a 2:1 vertical margin and the made-to-order 175 mm stroke covers the full lift height.
Lab sample indexing
Advancing sample trays between test stations in a compact analyzer chassis, where the short body fits where a full-length profile cylinder cannot and CMSE switches mark each end of travel.
Replacing the Airtac ACP Compact Cylinder ACP20X175S with the ACE20X175S
At 157.1 N push at 0.5 MPa this 20 mm bore sits between the 16 mm bore (100.5 N) and the 25 mm bore (245.4 N); step up if your mechanism needs more than about 94 N of working force. The 175 mm stroke is non-standard for this bore - it is built to order. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face family, and the fitted -S magnet accepts CMSE / DMSE switches. Remember a plain cylinder drifts when air is lost, so add a rod lock or pilot check valve for held loads. For new projects order the ACE20X175, the current drop-in successor, and confirm ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACE20X175S
- ✓ 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 ACP20X175S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa, 219.9 N push and 164.9 N pull; theoretical maximum 32 kgf at 1.0 MPa. It is a double acting 20 mm bore with a 175 mm made-to-order stroke, 10 mm rod with female M6x1.0 thread, M5x0.8 ports, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and a fixed TPU bumper at both ends. The model is discontinued; ACE20X175 is the replacement.
The hard-anodized aluminium body is a short ISO 21287-class build, saving about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guards. This version carries the optional -S magnet, letting you fit CMSE or DMSE reed or solid-state switches for position feedback. FA/FB flange, LB foot and CA/CB clevis brackets are available. Before ordering, confirm ISO 21287 mounting dimensions for the ACE20X175 successor, since the ACP was built to a DIN standard.
