This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-30 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 ACPJ20X110-30
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30 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 ACEJ20X110-30 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30
The ACPJ20X110-30 is a double acting compact cylinder with an adjustable stroke: a stop screw on the external stop trims the extend stroke by up to 30 mm, giving a usable range of 80-110 mm on site. Its 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N at 0.7 MPa, with a fixed TPU bumper at each end. The 110 mm stroke exceeds the 100 mm standard limit for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves roughly 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. In practice, plan on about 94 N of usable push at 0.5 MPa, which lifts roughly 8 kg vertically with a 2:1 margin. Note this model is discontinued; the current-production drop-in is the ACEJ20X110, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-30 (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 ACEJ20X110-30 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 ACPJ20X110-30 Is Used
Fixture clamping on CNC jigs
Trims the extend stroke from 110 mm down to 80 mm with the stop screw so the clamp nose seats on varying part heights without repositioning the cylinder.
Packaging line push-off arms
The 157.1 N push at 0.5 MPa nudges cartons off a conveyor lane, and the short body fits under low guard rails.
Lab sample press station
About 8 kg of vertical lift capacity with a 2:1 margin suits pressing sample trays or lids in small automated test rigs.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30 with the ACEJ20X110-30
At 20 mm bore this sits above the 16 mm size (100.5 N push at 0.5 MPa) and below the 25 mm class, so choose it when 157.1 N at 0.5 MPa covers the job with margin. The stop screw only shortens the extend stroke within the 30 mm window and does not lock the piston - on air loss the rod still drifts, so add a separate clamp if you must hold a load. FA/FB flange and LB foot mountings bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches; this code has no magnet. Order the ACEJ20X110 instead, as this model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-30
- ✓ 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 ACPJ20X110-30 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. The -30 code gives a 30 mm adjustment window, so the extend stroke is trimmed anywhere between 80 and 110 mm. The 110 mm stroke is a non-standard, made-to-order length because the bore's standard limit is 100 mm.
The hard-anodized aluminium body follows the short ISO 21287-class format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with M5x0.8 ports, an M6x1.0 female rod thread and fixed TPU bumpers at both ends. The ACPJ family is discontinued; the current drop-in is the ACEJ20X110 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Add the -S code if you need the optional magnet for CMSE / DMSE switches.
