This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-40 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 ACPJ20X160-40
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40 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 ACEJ20X160-40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40
This ACPJ20X160-40 is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 160 mm stroke by up to 40 mm on site, giving a usable range of 120-160 mm. The 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. Note the 160 mm stroke is beyond the 100 mm standard maximum for bore 20, so it is a made-to-order stroke. This model is discontinued; the current-production replacement is ACEJ20X160, same bore, stroke and force class.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and gantries. A fixed TPU bumper sits at both ends and the hard-anodized aluminium body carries an S45C hard-chrome 10 mm rod with a female M6x1.0 thread. For sizing, plan on roughly 94 N (about 9.6 kg of thrust) of real work at 0.5 MPa, and expect around 8 kg of vertical lift capability with a 2:1 margin. No magnet is fitted, so position switches cannot be used unless you order the -S variant; speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-40 (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 ACEJ20X160-40 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 ACPJ20X160-40 Is Used
Fixture clamp tuning
The 40 mm adjustment window lets a jig builder dial in the exact clamp position on a 157.1 N push at 0.5 MPa without shimming.
Small part ejector
Ejects molded caps or stamped blanks from a die, with the 120-160 mm stroke range matched to the part drop height.
Gate diverter pusher
Pushes cartons off a light conveyor lane; the compact body fits between guard rails where a full-length cylinder will not.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40 with the ACEJ20X160-40
Choose this model when a 20 mm bore fits the load: 157.1 N push at 0.5 MPa covers light clamping and indexing, while a 16 mm bore gives only 100.5 N and a 25 mm class step up is needed for more force. The -40 window suits fixtures where the final extend position is tuned during commissioning; remember the stop only shortens the stroke and does not hold a load if air is lost. Mount with FA/FB flange or LB foot on the ISO 21287 face, and order the -S code if CMSE / DMSE switches are planned. Before ordering, confirm the made-to-order 160 mm stroke lead time and verify ACEJ20X160 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-40
- ✓ 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 ACPJ20X160-40 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. The -40 code gives a 40 mm adjustment window, so the 160 mm extend stroke can be trimmed anywhere in a 120-160 mm range. The 160 mm stroke is a made-to-order length since bore 20 tops out at 100 mm standard.
An external stop screw mechanically limits the extend stroke within the ordered 40 mm window; it shortens the stroke only and never lengthens it past 160 mm. It is an end stop, not a mid-stroke lock, so the rod still drifts if air pressure is lost. This version has no magnet, so CMSE or DMSE switches cannot be fitted; order the -S variant to enable them.
