This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X150-20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X150-20B 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 ACPJ16X150-20B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-20B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm 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 ACEJ16X150-20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-20B
This is a double acting compact cylinder with an adjustable extend stroke, built on the DIN-standard ACPJ short body: hard-anodized aluminium covers threaded onto the body, an S45C hard-chrome piston rod and a fixed TPU bumper at each end. The 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa. The 150 mm stroke is longer than the 75 mm standard maximum for this bore, so it is a made-to-order build. Note: the ACPJ family is discontinued; the current-production replacement is the ACEJ16X150, so confirm ISO 21287 mounting dimensions before swapping.
The -20 code gives a 20 mm adjustment window: a stop screw trims the extend stroke anywhere between 130 and 150 mm on site, so one cylinder serves several jig positions. In practice, plan on roughly 60 N of usable push at 0.5 MPa, which lifts about 3 kg vertically with a sensible margin. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and this unit has a male rod thread (B code) with PT ports. No magnet is fitted because the -S code was not ordered, so position switches cannot be mounted on this version.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X150-20B (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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
The ACEJ16X150-20B 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 ACPJ16X150-20B Is Used
Compact ejection station
A 150 mm throw with a 20 mm trim window ejects finished parts from a small fixture; the roughly 60 N usable push at 0.5 MPa handles light plastic or thin aluminium components.
Clamping on a multi-part jig
The 130-150 mm adjustable range lets one cylinder serve jig variants without re-plumbing; the male rod thread (B) accepts an I/Y knuckle for angled clamping pads.
Small parts press-fit
About 3 kg of vertical working force at 0.5 MPa presses dowels or bearings into housings on an assembly bench, with the TPU bumpers decelerating each end of travel.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-20B with the ACEJ16X150-20B
Size against neighbours: the 12 mm bore gives 56.5 N push at 0.5 MPa, while the 20 mm bore reaches 157.1 N - step up if your part weight or friction load exceeds the roughly 60 N usable figure of this 16 mm bore. The stop screw is a mechanical end stop for the extend stroke only; on air loss the piston still drifts, so it is not a mid-stroke lock. FA/FB flange or LB foot mounts bolt to the standard face, and ordering the -S variant adds the optional magnet for CMSE / DMSE switches. For new projects, specify the ACEJ16X150 instead, since this ACPJ model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X150-20B
- ✓ 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 ACPJ16X150-20B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. The -20 code gives a 20 mm window, so the extend stroke can be trimmed from 150 mm down to 130 mm with the stop screw. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 150 mm stroke is a made-to-order length since the bore 16 standard maximum is 75 mm.
Switches need the optional -S magnet, which this unit does not carry, so no CMSE / DMSE sensor can be mounted on this version - order an -S variant if sensing is required. The ACPJ family is discontinued; the current-production drop-in is the ACEJ16X150 in the same bore, stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping.
