This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X70 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X70 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 ACP20X70
The AirTAC Airtac ACP Compact Cylinder ACP20X70 is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X70 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X70
The ACP20X70 is a double acting DIN-standard compact cylinder with a 20 mm bore and 70 mm stroke, built around a hard-anodized aluminium body and an S45C hard-chrome rod. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N push at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The short ISO 21287-class body saves about 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.
Practical sizing: plan on roughly 94 N (about 9.6 kg of vertical lift) of real work at 0.5 MPa, halving the 16 kgf theoretical lift for a 2:1 margin. The fixed TPU bumper at each end only softens end-of-travel; it never holds a load, so use a rod lock or pilot check valve if the position must survive lost air. Note that this model is discontinued - the current-production drop-in is the ACE20X70, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X70 (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 ACE20X70 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 ACP20X70 Is Used
Small-parts clamping fixture
A CNC side clamp on aluminium brackets needs about 90 N of holding force; the 157.1 N push at 0.5 MPa covers it with margin inside a 70 mm stroke.
Packaging line pusher
Diverting cartons on a conveyor at 30-500 mm/s suits the short body, which fits under low guard rails where a full-length profile cylinder cannot.
Lab test station actuator
Pressing sample trays into a test nest uses the 117.8 N pull stroke for retraction, with the M5x0.8 ports fed from a compact manifold.
Replacing the Airtac ACP Compact Cylinder ACP20X70 with the ACE20X70
For a 70 mm stroke in this force band, compare the 16 mm bore (100.5 N push at 0.5 MPa) if the load is light, or step up to the 25 mm bore (245.4 N push) for heavier clamping. The 20 mm bore keeps the body short while still delivering 157.1 N. Rod end is female M6x1.0 with a PT port; FA/FB flange, LB foot and CA/CB clevis mounts bolt to the standard face. Position sensing requires the optional -S magnet code with CMSE or DMSE switches - without -S there is no magnet. Order the ACE20X70 as the current replacement and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE20X70
- ✓ 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 ACP20X70 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N. Theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um.
No - the ACP family is discontinued. The current-production drop-in is the ACE20X70 (swap the P for an E), which matches the same 20 mm bore, 70 mm stroke and force class in the ISO 21287 short body. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the DIN standard.
