This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X75S 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 ACP20X75S
The AirTAC Airtac ACP Compact Cylinder ACP20X75S is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X75S
Double acting on a 20 mm bore, the ACP20X75S delivers 157.1 N push and 117.8 N pull at 0.5 MPa, 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 cuts 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. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the barrel for end-of-stroke sensing.
Build quality is typical AirTAC: a hard-anodized aluminium body with threaded aluminium covers, an S45C hard-chrome piston rod, a two-way grease-storing piston seal and fixed TPU bumpers at both ends. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it covers 30-500 mm/s between -20 and +70 C. Note that ACP is discontinued: the current-production successor is the ACE20X75, so confirm ISO 21287 mounting dimensions before ordering. As a rule of thumb, plan on about 94 N (roughly 9.6 kg, or about 4.8 kg vertical with a 2:1 margin) of usable work from the 157.1 N push rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X75S (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 ACE20X75S 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 ACP20X75S Is Used
Small-parts clamping on CNC fixtures
The 157.1 N push at 0.5 MPa is enough to hold aluminium or plastic workpieces in a drilling or milling jig, and the short body fits inside fixture plates where clamp space is scarce.
Indexed slide with position feedback
Because the -S magnet is fitted, CMSE or DMSE switches confirm extend and retract on a 75 mm indexing move in electronics assembly or lab automation at up to 500 mm/s.
Push-off on compact packaging heads
With about 9.6 kg of practical working force, the cylinder ejects cartons or blisters from a forming station on a packaging line without needing a longer ISO 15552 body.
Replacing the Airtac ACP Compact Cylinder ACP20X75S with the ACE20X75S
At 75 mm stroke this sits inside the 100 mm standard stroke limit for the 20 mm bore, so no made-to-order barrel is needed. If 157.1 N push at 0.5 MPa is marginal for the load, step up to the 25 mm bore (245.4 N push); if the force is generous, the 16 mm bore (100.5 N push) saves space. The female M6x1.0 rod thread and PT ports suit standard fittings, and FA/FB flange, LB foot or CA/CB clevis mounts keep fixture changes simple. For a load that must stay put when air is lost, add a rod lock or pilot check valve - the bumper does not hold position. Order the ACE20X75 as the current drop-in replacement.
Replacement checklist
- ✓ Current-production ACE → ACE20X75S
- ✓ 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 ACP20X75S 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. The theoretical maximum is 32 kgf at 1.0 MPa. It is double acting, so air drives the rod in both directions, and speed ranges from 30-500 mm/s at 0.15-1.0 MPa (22-145 psi) supply.
Order the ACE20X75, the current ISO 21287 successor: swap the P for an E and you get the same 20 mm bore, 75 mm stroke and force class in a matching short body. The ACE keeps the FA/FB flange, LB foot and CA/CB clevis mounting family, but because the ACP was built to the DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping.
