This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-100B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-100B 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 ACPJ20X160-100B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-100B 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 ACEJ20X160-100B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-100B
This discontinued AirTAC ACPJ20X160-100B is a double acting compact cylinder with an adjustable stroke: a stop screw trims the 160 mm extend stroke by up to 100 mm, giving a usable range of 60-160 mm. The 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N push at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa. Its 160 mm stroke exceeds the 100 mm standard maximum 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, which is why it slots into cramped gantries and guarding frames. Practical sizing: keep real work near 94 N (about 0.6 of the push rating), and for vertical lifts expect roughly 8 kg with a 2:1 margin. Note the male rod thread (B code) and PT ports; this unit has no magnet, since the magnet is only supplied with the optional -S code. Replacement: ACEJ20X160.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-100B (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 ACEJ20X160-100B 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 ACPJ20X160-100B Is Used
Small-parts press station
The 157.1 N push at 0.5 MPa suits light pressing of connectors or bushings in electronics assembly, with the 60-160 mm adjustable range tuned per fixture.
Pick-and-place lift on a compact gantry
Lifts about 8 kg vertically with a 2:1 margin, and the short body fits gantry beams where a full-length profile cylinder cannot.
Packaging line reject pusher
Trims the extend stroke down to 60 mm via the stop screw so cartons are nudged off a conveyor without overtravel, at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-100B with the ACEJ20X160-100B
Size against neighbours: a 16 mm bore gives 100.5 N push at 0.5 MPa, while stepping up to 25 mm-class bores adds force at the cost of length. For this 20 mm model, plan around 94 N of usable push at 0.5 MPa. The adjuster is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so do not treat it as a load-holding brake. 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 ACEJ20X160 as the current drop-in and confirm ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-100B
- ✓ 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 ACPJ20X160-100B FAQ
At 0.5 MPa: 157.1 N push and 117.8 N pull. At 0.7 MPa: 219.9 N push and 164.9 N pull. Theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um, M5x0.8 ports, 10 mm rod with male thread (B code).
An external stop screw shortens the 160 mm extend stroke by up to 100 mm, so the working range is 60-160 mm; it cannot lengthen the stroke beyond 160 mm. The fixed TPU bumper at both ends simply decelerates the piston at each end of travel. ACPJ is discontinued - the current-production replacement is ACEJ20X160, a drop-in in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, as the ACP series follows the DIN-standard footprint.
