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

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-100S
The ACPJ20X160-100S is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 160 mm stroke by up to 100 mm, giving a usable range of 60-160 mm. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke signalling. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The 160 mm stroke exceeds the 100 mm maximum standard stroke for the 20 mm bore, so it is a non-standard, made-to-order build.
The hard-anodized aluminium body with an S45C hard-chrome rod is an ISO 21287 class short build that saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jig plates and gantry frames. As a rule of thumb, plan on about 94 N (roughly 9.6 kg) of real work at 0.5 MPa, which lifts about 8 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, and the family is discontinued: the current-production drop-in is the ACEJ20X160, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-100S (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 ACEJ20X160-100S 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 ACPJ20X160-100S Is Used
Jig plate ejector
Trims from 160 mm down to 60 mm on the stop screw to eject machined aluminium housings from a drill jig, using about 94 N of usable push at 0.5 MPa.
Battery tray gate pusher
The 8 kg vertical-lift equivalent and 157.1 N push at 0.5 MPa suit pushing battery trays off a warehouse gate conveyor within the 60-160 mm trimmed range.
Pick station part present check
With the -S magnet fitted, a DMSE switch signals full extension on a small-parts pick station, confirming the gripper has seated the component.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-100S with the ACEJ20X160-100S
Size against neighbours: the 16 mm bore gives 100.5 N push at 0.5 MPa, while stepping up to a larger bore adds force if 157.1 N is marginal for your part weight. 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 where a load must stay put. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. Note the ACPJ line is discontinued; the ACEJ20X160 is the current replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-100S
- ✓ 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 ACPJ20X160-100S 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 -100 code gives a 100 mm adjustment window, so the stop screw trims the 160 mm extend stroke anywhere down to 60 mm. The 160 mm stroke is a non-standard, made-to-order length because the 20 mm bore normally tops out at 100 mm standard.
It is a short ISO 21287 class build in hard-anodized aluminium with an S45C hard-chrome rod, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and M5x0.8 ports. The ACPJ family is discontinued; the ACEJ20X160 is the current-production drop-in with the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
