This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X175 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X175 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 ACP20X175

About the Airtac ACP Compact Cylinder ACP20X175
The ACP20X175 is a double acting DIN-standard compact cylinder with a 20 mm bore and a 175 mm stroke, driving a 10 mm hard-chrome S45C rod through a female M6x1.0 thread. It 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. Air supply runs 0.15-1.0 MPa (22-145 psi) and rod speed 30-500 mm/s.
Because the short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into narrow slides and fixture plates a full-length body cannot reach. Plan on roughly 94 N of usable push at 0.5 MPa, which lifts about 8 kg vertically with a 2:1 margin. The 175 mm stroke is beyond the 100 mm standard for this bore, so it is made to order. This model is discontinued; the current-production drop-in is ACE20X175, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X175 (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 ACE20X175 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 ACP20X175 Is Used
Fixture clamping on a CNC jig
The 157.1 N push at 0.5 MPa holds small aluminium brackets against a locating stop inside a tight machining fixture where the short body fits between clamp posts.
Lift-assist ejector in a small press
With about 8 kg of vertical lift capacity at a 2:1 margin, the cylinder raises finished plastic caps clear of a mold nest on each cycle.
Pusher on a packaging line
The 175 mm made-to-order stroke sweeps cartons sideways across a 160 mm conveyor lane at up to 500 mm/s, using the fixed TPU bumper to decelerate at each end.
Replacing the Airtac ACP Compact Cylinder ACP20X175 with the ACE20X175
Size the load both ways: a 16 mm bore gives 100.5 N push at 0.5 MPa, while a 25 mm bore reaches 245.4 N, so the 20 mm sits between them at 157.1 N. If the load must stay put when air is lost, add a rod lock or pilot check valve, since the piston drifts once pressure drops. Order the -S code if you need the optional magnet for CMSE / DMSE switches; this plain model has no magnet. FA/FB flange, LB foot and CA/CB clevis brackets bolt to the standard face. The 175 mm stroke is non-standard, and the current replacement is ACE20X175.
Replacement checklist
- ✓ Current-production ACE → ACE20X175
- ✓ 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 ACP20X175 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. It is a double acting compact cylinder, 20 mm bore, 175 mm non-standard 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, with a fixed TPU bumper at both ends.
Order ACE20X175, the ISO 21287 successor made by swapping the P for an E. It matches the same 20 mm bore, 175 mm stroke and force class, so confirm the ISO 21287 mounting dimensions against your fixture before the swap. If you need position sensing, order the -S variant with the optional magnet for CMSE / DMSE switches.
