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

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40B
This is a double acting compact cylinder with an adjustable extend stroke, built on a hard-anodized aluminium body with an S45C hard-chrome rod. 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 peak of 32 kgf at 1.0 MPa. Its 160 mm stroke is a made-to-order length, since the standard catalog limit for this bore is 100 mm. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding where a full-length body cannot.
The -40 code gives a 40 mm adjustment window: an external stop screw trims the extend stroke anywhere within 120-160 mm on site, so one cylinder can serve several fixture positions. Plan on about 94 N of usable push at 0.5 MPa, which lifts roughly 9 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, and the B code specifies a male rod thread. Note this model is discontinued; the current-production drop-in is the 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 ACEJ20X160-40B (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 ACEJ20X160-40B 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 ACPJ20X160-40B Is Used
Fixture clamping on a CNC jig
The 120-160 mm adjustable range lets one cylinder clamp different part heights on a machining fixture, with about 94 N of usable push at 0.5 MPa for light clamping plates.
Reject pusher on a packaging line
A stop screw trims the extend stroke to match lane width, and the compact body fits inside conveyor guarding where a full-length profile cylinder will not.
Sample lift in a lab automation gantry
With a 10 mm male-thread rod and roughly 9 kg vertical lift capacity at a 2:1 margin, it raises small sample trays inside tight Z-axis frames.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40B with the ACEJ20X160-40B
Size against the load: the 20 mm bore gives 157.1 N push at 0.5 MPa, while a 16 mm bore manages only 100.5 N and a 25 mm-class step up adds force you may not need. If the cylinder must hold a load through a power loss, remember the stop screw sets the end position only - the piston still drifts when air is lost, so add a separate locking solution. Mounting uses FA/FB flanges or LB feet on the ISO 21287 face, and position sensing requires the optional -S magnet code for CMSE / DMSE switches; this unit has no magnet fitted. Order the ACEJ20X160 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-40B
- ✓ 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 ACPJ20X160-40B 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. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 160 mm extend stroke to any length from 120 to 160 mm. It sets the end position only and does not hold a load on air loss.
No - the ACPJ family is discontinued. The current-production drop-in is the ACEJ20X160, which swaps the P for an E and matches the same 20 mm bore, 160 mm stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. Also note the 160 mm stroke is a made-to-order length, and sensors need the optional -S magnet with CMSE / DMSE switches.
