This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X150-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X150-30 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 ACPJ20X150-30
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-30 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X150-30 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-30
This is a double acting compact cylinder with an adjustable extend stroke: the -30 code gives a 30 mm window, so the external stop screw trims the 150 mm stroke anywhere down to 120 mm on site. The 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa (219.9 N / 164.9 N at 0.7 MPa, 32 kgf theoretical max at 1.0 MPa). The 150 mm stroke exceeds the 100 mm standard limit for bore 20, so it is a made-to-order build. Note this model is discontinued - the current-production replacement is the ACEJ20X150, so confirm ISO 21287 mounting dimensions before swapping.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits long-stroke jobs inside tight gantries and sliding guards. In practice, plan on about 94 N (roughly 9.6 kgf) of usable push at 0.5 MPa, enough to lift about 8 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X150-30 (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 ACEJ20X150-30 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 ACPJ20X150-30 Is Used
Pick-and-place elevator arm
With about 8 kg of vertical lift capacity at a 2:1 margin, the 150 mm stroke raises small plastic trays between a conveyor and an inspection bench.
Conveyor gate diverter
The 120-150 mm adjustable throw pushes cartons off a packaging line into a reject lane, with the stop screw tuned to the lane width.
Gantry slide feed
The short body fits inside a compact CNC loading gantry where a full-length profile cylinder would not, feeding parts 150 mm into a fixture.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-30 with the ACEJ20X150-30
Size up from the 16 mm bore (100.5 N push at 0.5 MPa) if 157.1 N is more than the job needs, or step to a larger bore for heavier clamping. The adjuster is a mechanical end stop for the extend stroke only - it does not hold a load if air is lost, so add a separate lock for suspended weight. FA/FB flanges and LB feet bolt to the ISO 21287 face; order the -S code if you later want CMSE / DMSE switches, since this version has no magnet. For new designs, specify the ACEJ20X150 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X150-30
- ✓ 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 ACPJ20X150-30 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; theoretical maximum is 32 kgf at 1.0 MPa. The -30 code sets a 30 mm adjustment window: a stop screw shortens the extend stroke from 150 mm down to 120 mm. The 150 mm stroke is non-standard for bore 20 (100 mm max standard) and is made to order.
The ISO 21287-class short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange and LB foot options on the standard face. The ACPJ family is discontinued; the current drop-in is the ACEJ20X150 (same bore, stroke and force class) - verify ISO 21287 mounting dimensions before swapping. This version has no magnet; the -S code adds one for CMSE / DMSE switches.
