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

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-30
This double acting ACPJ20X160-30 is a discontinued DIN-standard compact cylinder with a 30 mm adjustment window: a stop screw trims the 160 mm extend stroke down to 130 mm on site, so one unit covers a 130-160 mm working range. 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 fixed TPU bumper at each end and speeds of 30-500 mm/s. Note the 160 mm stroke exceeds the 100 mm standard maximum for this bore, so it is made to order.
The hard-anodized aluminium body with an S45C hard-chrome 10 mm rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped jigs and gantries. In practice, plan on about 94 N of usable push at 0.5 MPa (a 0.6 derating rule), which lifts roughly 8 kg vertically with a 2:1 margin. This model has no magnet fitted; order the optional -S code if you need CMSE / DMSE switch sensing. It 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 ACEJ20X160-30 (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 ACEJ20X160-30 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 ACPJ20X160-30 Is Used
Fixture clamping with trimmed stroke
On a CNC jig for aluminium brackets, the stop screw sets the clamp stroke anywhere from 130 to 160 mm, and the 157.1 N push at 0.5 MPa seats the part without crushing thin walls.
Small parts ejector on a press bench
Pushes finished bushings off a die plate at up to 500 mm/s; the roughly 8 kg vertical-lift equivalent means it also handles light lift-and-lower chutes.
Product divert on a packaging line
The short body fits under a tight conveyor guard where a full-length profile cylinder will not, kicking cartons onto a reject lane within the 130-160 mm stroke range.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-30 with the ACEJ20X160-30
Size both ways: the 16 mm bore gives 100.5 N push at 0.5 MPa if your load is lighter, while the 25 mm class in the ACE range adds margin if 157.1 N feels tight. Remember the stop screw only shortens the extend stroke within the 30 mm window and is not a mid-stroke lock - the rod still drifts if air is lost, so add a separate valve or clamp for load holding. FA/FB flange and LB foot mountings bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches. For new projects, specify the ACEJ20X160 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-30
- ✓ 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 ACPJ20X160-30 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. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s. The 160 mm stroke is a made-to-order length above the 100 mm standard maximum for the 20 mm bore.
An external stop screw shortens the extend stroke by up to 30 mm inside the ordered window, giving a usable 130-160 mm range; it cannot lengthen the stroke past 160 mm and it does not hold a load on air loss. This ACPJ is discontinued - the current-production replacement is the ACEJ20X160 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the older DIN-standard footprint.
