This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-10 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 ACPJ20X160-10
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-10 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X160-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-10
Double acting and adjustable in stroke, the ACPJ20X160-10 is a discontinued DIN-standard compact cylinder: a 20 mm bore pushing 157.1 N at 0.5 MPa (219.9 N at 0.7 MPa) through a 160 mm stroke that a stop screw trims by up to 10 mm, giving a usable 150-160 mm extend range. The 160 mm stroke exceeds the 100 mm standard limit for this bore, so it is made to order. Its hard-anodized aluminium short body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into cramped jig plates and guard frames.
For sizing, plan on about 94 N of real work at 0.5 MPa rather than the full 157.1 N rating - roughly 9.6 kgf, so it lifts about 4.8 kg vertically with a 2:1 margin. The rod end carries a female M6x1.0 thread and the ports are M5x0.8. This model is discontinued; the current-production drop-in is the ISO 21287 ACEJ20X160 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-10 (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 ACEJ20X160-10 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 ACPJ20X160-10 Is Used
Fixture clamp with trimmed stroke
On a CNC jig plate the 10 mm stop screw lets a machinist dial the 160 mm extend down to 150 mm so the clamp pad seats on a milled step without bottoming hard against the fixed TPU bumper.
Small-part pusher on a packaging line
With 157.1 N push at 0.5 MPa the cylinder ejects blister packs or carton blanks off a conveyor lane, and the short body fits the 120 mm gap beside the guide rail where a full-length cylinder cannot.
Sample lift in a lab automation rig
Lifting about 4.8 kg vertically with a 2:1 margin, the 20 mm bore raises microplate stacks or reagent trays between two deck heights at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-10 with the ACEJ20X160-10
At 20 mm bore this sits mid-range: the 16 mm bore delivers 100.5 N push at 0.5 MPa while the next size up in the family reaches 219.9 N at 0.7 MPa for heavier clamps. The -10 stop screw only shortens the extend stroke; it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. Order the -S code if you need the optional magnet for CMSE / DMSE switches - this version has no magnet, so no sensor can be mounted. FA/FB flange and LB foot mountings bolt to the standard face. Since the ACPJ is discontinued, spec the ACEJ20X160 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-10
- ✓ 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 ACPJ20X160-10 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, with a theoretical maximum of 32 kgf at 1.0 MPa. The -10 code gives a 10 mm adjustment window: a stop screw shortens the 160 mm extend stroke to as little as 150 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, -20 to +70 C, with a fixed TPU bumper at both ends.
The standard stroke limit for bore 20 is 100 mm, so 160 mm is a non-standard, made-to-order stroke - allow extra lead time. The ACPJ family itself is discontinued: the current-production replacement is the ACEJ20X160, an ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping, and add the -S code if you need the optional magnet for CMSE / DMSE switches.
