This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X20 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 ACP20X20
The AirTAC Airtac ACP Compact Cylinder ACP20X20 is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X20
A double acting compact cylinder in the DIN-standard ACP series, the ACP20X20 pairs a 20 mm bore with a 20 mm stroke and delivers 157.1 N push and 117.8 N pull at 0.5 MPa (219.9 N / 164.9 N at 0.7 MPa). The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped fixtures where a full-length body cannot. Air supply is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and speed runs 30-500 mm/s.
Practical sizing: plan on about 94 N of real work at 0.5 MPa (roughly 60% of the rated push), which means this unit lifts about 8 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and the rod ends in a female M6x1.0 thread with an M5x0.8 supply port. This model is discontinued; the current-production drop-in is ACE20X20, so confirm ISO 21287 mounting dimensions before swapping. Note there is no magnet fitted - order the -S code to enable CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X20 (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 ACE20X20 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 ACP20X20 Is Used
Small-part ejection on rotary tables
A 20 mm stroke is ideal for knocking finished bushings or spacers off a rotary indexing table into a chute, with 157.1 N push at 0.5 MPa ample for light aluminium parts.
Lab sample press fixture
Compact benchtop test rigs pressing sensor caps or vial stoppers benefit from the short body; about 8 kg of vertical lift capacity covers typical sample weights with margin.
Carton flap tuck station
Tucking minor flaps on cosmetic or pharmaceutical cartons needs a fast, short-throw push - the 30-500 mm/s speed range and fixed TPU bumpers suit high-cycle tuck arms.
Replacing the Airtac ACP Compact Cylinder ACP20X20 with the ACE20X20
At 157.1 N push at 0.5 MPa, the 20 mm bore sits between the 16 mm bore (100.5 N push) and the 25 mm bore (245.4 N push) - step down for lighter clamping, up if your load needs more margin. Remember a plain ACP drifts when air is lost; add a rod lock or pilot check valve if the load must hold. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the standard face, and the optional -S magnet enables CMSE / DMSE position switches. For new builds, order ACE20X20 instead - it is the current ISO 21287 successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACE20X20
- ✓ 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 ACP20X20 FAQ
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It is double acting with a 20 mm bore, 20 mm stroke, 10 mm rod, M5x0.8 port and female M6x1.0 rod thread, running on 0.15-1.0 MPa (22-145 psi) air at 30-500 mm/s. The model is discontinued - ACE20X20 is the current replacement.
The short ISO 21287-class body cuts mounting length by about 50% versus an ISO 15552 profile cylinder, and FA/FB flange, LB foot or CA/CB clevis mountings bolt straight on. Sensing requires the optional -S magnet code - without it no magnet is fitted and no switch can be used; with -S, CMSE or DMSE switches track rod position. Confirm ISO 21287 dimensions before swapping to the ACE20X20 successor.
