This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-100 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 ACPJ20X110-100
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100 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 ACEJ20X110-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100
The ACPJ20X110-100 is a double acting, adjustable-stroke compact cylinder in the discontinued AirTAC ACPJ family. Its 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa (219.9 N push at 0.7 MPa), with a theoretical peak of 32 kgf at 1.0 MPa. The 110 mm stroke exceeds the 100 mm standard limit for this bore, so it is a made-to-order build. The -100 code sets a 100 mm adjustment window: an external stop screw trims the extend stroke anywhere from 10 mm to the full 110 mm on site.
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 gantries. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper at each end, and an M6x1.0 female rod thread with M5x0.8 ports. No magnet is fitted on this version - the optional -S code adds one for CMSE / DMSE switches. In practice, plan on about 94 N (roughly 9.6 kg of push) for real work at 0.5 MPa, or about 8 kg of vertical lift with a 2:1 margin. This model is discontinued; the current drop-in is the ACEJ20X110 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-100 (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 ACEJ20X110-100 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 ACPJ20X110-100 Is Used
In-die part ejection on a punch press
The 157.1 N push at 0.5 MPa ejects stamped brackets from a die, while the stop screw trims the extend stroke to match shallow die pockets without shimming.
Gate indexing on a small assembly machine
The 10-110 mm adjustable range lets one cylinder serve several fixture variants; the short body fits where an ISO 15552 profile cylinder cannot.
Sample press in a lab fixture
With a 2:1 margin the bore 20 rod lifts about 8 kg vertically, enough to lower and press sample trays in compact test rigs running 0.15-1.0 MPa (22-145 psi) air.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100 with the ACEJ20X110-100
Size against the load: bore 16 gives 100.5 N push at 0.5 MPa, while this 20 mm bore gives 157.1 N push and 117.8 N pull - pick the 20 mm when the extra 56 N matters or when the 10-110 mm trim range is needed. The stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts on air loss; add a separate valve or clamp if you must hold position. FA/FB flanges and LB feet bolt to the standard face, and CMSE / DMSE switches work only if you order the -S magnet version. Since ACPJ is discontinued, spec the ACEJ20X110 as the current-production equivalent and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-100
- ✓ 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 ACPJ20X110-100 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. It is double acting with a 20 mm bore, 110 mm made-to-order stroke (standard max for this bore is 100 mm), a 100 mm adjustment window, M5x0.8 ports, an M6x1.0 female rod thread, 10 mm rod, speed 30-500 mm/s, -20 to +70 C, air filtered to 40 um, and a fixed TPU bumper at both ends.
No. The maximum standard stroke for a 20 mm ACPJ bore is 100 mm, so the 110 mm stroke is a non-standard, made-to-order build. The whole ACPJ family is discontinued; the current-production drop-in is the ACEJ20X110 (same bore, stroke and force class). Because ACP is DIN-standard, confirm the ISO 21287 mounting dimensions of the ACEJ before swapping. Also note this version has no magnet - order the -S code if you need CMSE / DMSE switch sensing.
