This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X70S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X70S 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 ACP20X70S
The AirTAC Airtac ACP Compact Cylinder ACP20X70S 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 ACE20X70S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X70S
The ACP20X70S is a double acting DIN-standard compact cylinder with a 20 mm bore and 70 mm stroke. Air drives the rod in both directions, and fixed TPU bumpers at each end take the end-of-travel shock. 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 ceiling of 32 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures a full-length cylinder cannot reach.
The S in the code means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the hard-anodized aluminium body. In practice, plan on about 94 N of usable push at 0.5 MPa, which lifts roughly 4.8 kg vertically with a 2:1 margin - enough for small clamps, ejectors and light part transfer. Note this model is discontinued: the current-production replacement is ACE20X70, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X70S (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 ACE20X70S 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 ACP20X70S Is Used
Small jig clamping
With 157.1 N push at 0.5 MPa, the 20 mm bore clamps light aluminium brackets or plastic housings in drilling and assembly jigs where the 70 mm stroke sets the clamp travel.
Light part lifting
The usable vertical lift of about 4.8 kg with a 2:1 margin suits raising small machined blanks or SMT trays out of a nest at a test station.
Position-checked ejection
Because the -S magnet is fitted, CMSE or DMSE switches confirm end-of-stroke on a 70 mm ejector that pushes rejected components off a small conveyor line.
Replacing the Airtac ACP Compact Cylinder ACP20X70S with the ACE20X70S
Size between neighbours: the 16 mm bore gives 100.5 N push at 0.5 MPa, while the 25 mm bore reaches 245.4 N - pick the 20 mm when your load sits between those bands. The 70 mm stroke is within the 100 mm maximum standard stroke for this bore, so it is a catalogue item. Remember the plain cylinder drifts when air is lost; add a rod lock or pilot check valve if the load must stay put. This unit carries the optional -S magnet for CMSE / DMSE switches, uses a female M6x1.0 rod thread, and is discontinued in favour of ACE20X70.
Replacement checklist
- ✓ Current-production ACE → ACE20X70S
- ✓ 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 ACP20X70S 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 double acting with a 20 mm bore, 70 mm stroke, 10 mm rod, M5x0.8 ports, 0.15-1.0 MPa (22-145 psi) operating pressure, 1.5 MPa (215 psi) proof pressure, -20 to +70 C temperature range and 30-500 mm/s speed. The model is discontinued; ACE20X70 is the replacement.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow guards and tight gantries. The S code means the optional magnet is on this unit, so CMSE or DMSE reed or solid-state switches mount directly on the body for end-of-stroke signalling. FA/FB flange, LB foot and CA/CB clevis mountings are available, and the ACE20X70 successor should be checked against ISO 21287 dimensions before you swap.
