This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X30SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X30SB 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 ACP20X30SB
The AirTAC Airtac ACP Compact Cylinder ACP20X30SB is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X30SB
The ACP20X30SB is a double acting compact cylinder in the DIN-standard ACP series, with a 20 mm bore, 30 mm stroke and a male-threaded 10 mm 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 hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be fitted for end-position sensing.
Note for buyers: the ACP family is discontinued and AirTAC's current drop-in is the ISO 21287 ACE20X30, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on about 94 N (roughly 9.6 kg of vertical lift) of real work at 0.5 MPa rather than the full 157.1 N rating. The fixed TPU bumpers at both ends soften end-of-travel only; they do not hold a load, so use a rod lock or pilot check valve where position must be retained. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to +70 C.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X30SB (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 ACE20X30SB 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 ACP20X30SB Is Used
Small-part ejection from plastic moulds
The 157.1 N push at 0.5 MPa is enough to kick lightweight moulded clips off a ejector plate, and the 30 mm stroke matches shallow cavity depth.
Position-verified test fixture clamping
With the -S magnet fitted, CMSE or DMSE switches confirm the rod is fully forward before a PCB or sensor test cycle starts.
Packaging line pusher for carton diverting
A 30 mm stroke diverts small cartons between conveyor lanes, and the short body fits inside the machine frame where a longer cylinder cannot.
Replacing the Airtac ACP Compact Cylinder ACP20X30SB with the ACE20X30SB
At 157.1 N push at 0.5 MPa this 20 mm bore suits light clamping and small part transfer. If your load needs more, the 25 mm bore delivers 245.4 N at the same pressure; if less is enough, the 16 mm bore gives 100.5 N. The 30 mm stroke sits well inside the 100 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order length. The B code gives a male rod thread (M6x1.0 female is the alternative), and the PT port thread takes M5x0.8 fittings. Foot, flange and clevis brackets bolt to the standard face, and the fitted -S magnet lets CMSE / DMSE switches report rod position. Order the ACE20X30 instead - this ACP model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE20X30SB
- ✓ 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 ACP20X30SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa push is 219.9 N and pull 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 runs 30-500 mm/s across a 0.15-1.0 MPa (22-145 psi) supply.
Yes - the ACE20X30, AirTAC's current-production ISO 21287 compact cylinder, covers the same 20 mm bore, 30 mm stroke and force class. Because the ACP was built to a DIN standard, verify the ISO 21287 mounting dimensions and port orientation before ordering the swap.
