This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X20SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X20SB 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.

About the Airtac ACP Compact Cylinder ACP20X20SB
The ACP20X20SB is a double acting DIN-standard compact cylinder with a 20 mm bore and a 20 mm stroke, built around a hard-anodized aluminium body and an S45C hard-chrome piston rod. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical peak 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 jigs and guarding where a full-length body will not fit. The B code gives a male rod thread and the S code fits the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted directly on the tube.
This model is discontinued and no longer in production; the current drop-in successor is the ACE20X20, which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to the DIN standard. For planning, treat about 94 N (roughly 0.6 of the push force) as the usable working thrust at 0.5 MPa, which corresponds to lifting about 9 kg vertically - halve that to around 5 kg if you want a 2:1 margin on a real part weight. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X20SB (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 ACE20X20SB 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 ACP20X20SB Is Used
Small-part ejection on assembly fixtures
The 157.1 N push at 0.5 MPa is enough to kick finished bushings or caps off a nest, and the 20 mm stroke keeps the ejector flush inside a compact fixture plate.
Position-verified clamping of PCB test pallets
With the -S magnet fitted, CMSE or DMSE switches confirm clamp and release on each pallet, while the short body fits inside the guard envelope of a bench-top test rig.
Light press-fit and marking stations
About 9 kg of vertical thrust equivalent at 0.5 MPa suits staking small terminals or date-coding plastic housings on a rotary indexing table.
Replacing the Airtac ACP Compact Cylinder ACP20X20SB with the ACE20X20SB
At 20 mm bore this sits between the 16 mm (100.5 N push at 0.5 MPa) and the 25 mm (245.4 N push), so pick down if your load is under about 9 kg equivalent and up if you need more thrust margin. The 20 mm stroke is well inside the 100 mm maximum standard stroke for this bore, so it is a catalog item, not made to order. Note that a plain cylinder of this type does not hold position when air is lost - the piston drifts - so add a rod lock or pilot check valve if the load must stay put. Match FA/FB flange, LB foot or CA/CB clevis mounting to your fixture, and remember the -S magnet on this unit is what enables CMSE / DMSE switch position sensing. Order the ACE20X20 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACE20X20SB
- ✓ 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 ACP20X20SB 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. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s. Plan on roughly 94 N of usable working thrust at 0.5 MPa, about 9 kg of vertical lift equivalent.
Order the ACE20X20, the current ISO 21287 successor with the same 20 mm bore, 20 mm stroke and force class; confirm the mounting dimensions before swapping because the ACP followed the DIN standard. The ACP20X20SB itself is a compact double-acting cylinder with a hard-anodized aluminium body, male rod thread (B code), M5x0.8 ports, a fixed TPU bumper at both ends, and the optional -S magnet fitted so CMSE / DMSE switches can be mounted.
