This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-30B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-30B 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 ACPJ Adjustable Compact Cylinder ACPJ20X110-30B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X110-30B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30B
The ACPJ20X110-30B is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 110 mm stroke by up to 30 mm, giving a usable range of 80-110 mm. It is discontinued, and the current-production replacement is the ACEJ20X110, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. At 0.5 MPa this 20 mm bore pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it reaches 219.9 N push and 164.9 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding where a full-length body will not fit. Note the 110 mm stroke exceeds the 100 mm maximum standard stroke for bore 20, so this unit is made to order. A practical sizing rule: about 94 N (roughly 9.6 kgf) of the 157.1 N push is realistically usable at 0.5 MPa, which lifts about 4.8 kg vertically with a 2:1 margin. The B code gives a male 10 mm rod thread; the port is M5x0.8, and no magnet is fitted because the -S code was not ordered.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-30B (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 ACEJ20X110-30B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30B Is Used
Small-parts ejection on assembly fixtures
The 157.1 N push at 0.5 MPa clears a machined housing or stamped clip off a nest, and the 30 mm window lets the technician dial the eject distance between 80 and 110 mm without re-plumbing.
Label-press anvil on packaging lines
About 9.6 kgf of usable press force at 0.5 MPa seats labels or gaskets on cosmetic cartons, and the compact body fits the shallow head space above a conveyor.
Sample vial indexing in lab automation
The male-threaded 10 mm rod drives a lightweight indexer between vial racks, with the stop screw trimmed so the probe stops short of the rack wall; speed range 30-500 mm/s covers gentle and fast cycles.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30B with the ACEJ20X110-30B
Size by force: bore 16 delivers 100.5 N push at 0.5 MPa while bore 25 steps up from this 20 mm bore's 157.1 N - pick the smaller bore if your load is under about 9 kgf of working force. The 30 mm window suits machines where the final position is tuned on commissioning; remember the stop screw only shortens the extend stroke and drifts on air loss, so it is not a mid-stroke lock. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. If you need position sensing, order the -S variant to enable CMSE / DMSE switches - this B-coded model has no magnet. Replacement: ACEJ20X110.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-30B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30B 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. The -30 code is a 30 mm adjustment window: the stop screw shortens the 110 mm extend stroke by up to 30 mm, so the working range is 80-110 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 110 mm stroke is a made-to-order length since bore 20 tops out at 100 mm standard.
It is a short-body ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome rod, M5x0.8 ports, a male rod thread (B code) and a fixed TPU bumper at each end that only decelerates at the ends. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. The magnet is the optional -S code, so CMSE / DMSE switches work only on -S models. The ACPJ family is discontinued; the current drop-in is the ACEJ20X110 - confirm ISO 21287 mounting dimensions before swapping.
