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

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-100
This is a double acting compact cylinder with an adjustable extend stroke, built on the DIN-standard ACPJ short body: hard-anodized aluminium with an S45C hard-chrome 10 mm rod and a fixed TPU bumper at each end. The 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa (219.9 N / 164.9 N at 0.7 MPa), running on 0.15-1.0 MPa (22-145 psi) filtered air at 30-500 mm/s. Note that the 160 mm stroke exceeds the 100 mm standard maximum for bore 20, so this unit is a made-to-order build.
The -100 code is the adjustment window: a stop screw trims the extend stroke anywhere in a 60-160 mm range, so one cylinder serves several fixture positions. As a rule of thumb, plan on about 94 N of usable work at 0.5 MPa, which lifts roughly 4 kg vertically with a 2:1 margin. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange or LB foot mounts bolt straight on. This model is discontinued; the current-production replacement is ACEJ20X160, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-100 (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 ACEJ20X160-100 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 ACPJ20X160-100 Is Used
Bench-top press fixture
The 157.1 N push at 0.5 MPa suits light staking and marking on small aluminium brackets, with the 60-160 mm adjustable range letting one setup handle several part heights.
Compact pick-and-place gantry
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight Z-axes on electronics assembly gantries lifting parts up to about 4 kg.
Carton eject on packaging lines
At 30-500 mm/s the rod kicks finished cartons off a conveyor lane, and the stop screw lets operators dial the eject stroke down to 60 mm for narrow boxes.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-100 with the ACEJ20X160-100
Size up or down by force: bore 16 gives 100.5 N push at 0.5 MPa for lighter clamping, while stepping beyond bore 20 moves you toward larger compact frames. The stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, and on air loss the rod still drifts, so add a separate holding valve if the load must stay put. The female M6x1.0 rod thread takes standard I/Y knuckles; FA/FB flange and LB foot mounts fit the ISO 21287 face. If you need position feedback, order the -S variant with the optional magnet for CMSE / DMSE switches - this code has no magnet fitted. For new designs, specify the ACEJ20X160 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-100
- ✓ 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 ACPJ20X160-100 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. The theoretical maximum is 32 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s.
The -100 code is a 100 mm window: an external stop screw shortens the 160 mm extend stroke to any length down to 60 mm. It is an end stop, not a mid-stroke lock. The ACPJ family is discontinued; the current drop-in is the ACEJ20X160 in the same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping. Sensor-ready CMSE / DMSE switching requires the optional -S magnet code.
