This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X100B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X100B 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 ACP20X100B
The ACP20X100B is a double acting compact cylinder with a 20 mm bore and 100 mm stroke, built to the DIN-standard short-body format with a hard-anodized aluminium body, an S45C hard-chrome piston rod and a fixed TPU bumper at each end. 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 maximum of 32 kgf at 1.0 MPa. The B code gives a male rod thread on the 10 mm rod, and the air port is M5x0.8.
Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding where a full-length body will not fit. For sizing, treat roughly 0.6 of the push force as usable work at 0.5 MPa, about 94 N, which corresponds to lifting roughly 9 kg vertically - halve that to about 5 kg if you want a 2:1 margin. Note that this unit is discontinued: the current-production drop-in is the ACE20X100, so confirm the ISO 21287 mounting dimensions before swapping. The optional -S magnet code enables CMSE or DMSE switches; without it no magnet is fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X100B (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 ACE20X100B 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 ACP20X100B Is Used
Small-parts ejection on assembly benches
The 157.1 N push at 0.5 MPa is enough to kick finished connectors or PCBs out of a nest, and the 100 mm stroke clears a full bin width while the short body hides inside the bench frame.
Sample vial clamping in lab automation
With about 94 N of practical working force at 0.5 MPa, the cylinder grips 20-30 mm vials and sample trays firmly without crushing, and the M5x0.8 port keeps tubing runs compact.
Carton flap tucking on a packaging line
Running at 30-500 mm/s, the male-threaded rod drives a flap-tuck paddle through 100 mm of travel, folding top flaps on cosmetic or pharmaceutical cartons at moderate line speeds.
Replacing the Airtac ACP Compact Cylinder ACP20X100B with the ACE20X100B
At 20 mm bore this sits in the light-duty band: the 16 mm bore delivers 100.5 N push at 0.5 MPa while the 25 mm bore reaches 245.4 N, so step up if your mechanism needs more than about 94 N of working force. The 100 mm stroke is the maximum standard stroke for this bore, so longer strokes become made-to-order items. Choose the male rod thread (B) when your linkage screws onto the rod, and add FA/FB flange, LB foot or CA/CB clevis mounting to match the fixture. Remember the piston drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Order the ACE20X100 for current production and verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ACE20X100B
- ✓ 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 ACP20X100B FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa that rises to 219.9 N push and 164.9 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), speed range is 30-500 mm/s, and the fluid is air filtered to 40 um. It is double acting with a fixed TPU bumper at both ends.
Order the ACE20X100, the ISO 21287 successor: swap the P for an E and you get the same 20 mm bore, 100 mm stroke and force class in a matching short body. Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before the swap. If you need position feedback, the ACE accepts the same optional -S magnet arrangement for CMSE / DMSE switches.
