This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-30B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-30B 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 ACPJ20X160-30B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-30B 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 ACEJ20X160-30B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-30B
This double acting compact cylinder gives a 20 mm bore with a 160 mm stroke and a 30 mm adjustment window: a stop screw trims the extend stroke on site anywhere between 130 and 160 mm, so one unit covers several fixture positions. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, and the short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight gantries and guarding. Note that the 160 mm stroke exceeds the 100 mm maximum standard stroke for this bore, so it is a made-to-order build.
The B code gives a male rod thread on the 10 mm rod, and the port is M5x0.8. The body is hard-anodized aluminium with an S45C hard-chrome rod and fixed TPU bumpers at both ends; speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Because the adjuster is a mechanical end stop only, the piston will still drift if air is lost. As a rule of thumb, plan on roughly 94 N (about 9.6 kg of force) of real work at 0.5 MPa, and expect it to lift about 8 kg vertically with a 2:1 margin. This model is discontinued: the current drop-in is the ACEJ20X160, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-30B (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 ACEJ20X160-30B 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 ACPJ20X160-30B Is Used
Indexing fixture on a CNC line
The 130-160 mm adjustable extend stroke lets a machinist dial in clamp position per part family, with 157.1 N at 0.5 MPa enough for light aluminum jigs.
Carton kick-off on a packing table
A 160 mm push at 30-500 mm/s nudges boxes sideways into a lane; the male rod thread takes a knuckle for a swiveling push pad.
Small parts eject under a press
About 8 kg of vertical lift with a 2:1 margin clears stamped blanks off the die; the short body fits where a full-length profile cylinder cannot.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-30B with the ACEJ20X160-30B
Size against neighbours: the 16 mm bore pushes 100.5 N at 0.5 MPa, while the 20 mm bore here gives 157.1 N push and 117.8 N pull; step up only if you need more than about 94 N of usable force. The male rod thread (B) suits I/Y rod knuckles and external tooling, and FA/FB flange or LB foot mounts bolt to the standard face. If you need position sensing, order the -S version, since this code has no magnet and no switch can be fitted. For new builds, specify the ACEJ20X160 instead - it is the current-production successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-30B
- ✓ 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 ACPJ20X160-30B FAQ
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The 20 mm bore has an M5x0.8 port, a 10 mm male-thread rod, a 30 mm stroke adjustment window (usable 130-160 mm), and runs at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air. The 160 mm stroke is made to order, since the standard maximum for this bore is 100 mm.
An external stop screw shortens the extend stroke by up to 30 mm on site; it cannot lengthen the stroke past the ordered 160 mm, and it is not a mid-stroke lock, so the rod still drifts on air loss. This ACPJ is discontinued. The current-production replacement is the ACEJ20X160 (swap the P for an E) in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, because the ACP was built to the DIN standard.
