This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X150-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X150-50 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 ACPJ16X150-50
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-50 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 ACEJ16X150-50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-50
This is a double acting compact cylinder with an adjustable stroke: air drives the rod out and pulls it back, and a stop screw on the body trims the extend stroke anywhere inside the ordered 50 mm window, giving a usable range of 100-150 mm. At 0.5 MPa the 16 mm bore delivers 100.5 N push and 75.4 N pull, rising to 140.7 N push at 0.7 MPa, with a theoretical peak of 20.5 kgf at 1.0 MPa. The 150 mm stroke is longer than the 75 mm standard limit for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into cramped slide assemblies and fixture plates. In practice, plan on about 60 N of real work at 0.5 MPa, which lifts roughly 3 kg vertically once you keep a 2:1 margin. Note the fixed TPU bumper at each end only softens the ends of travel - it never holds or brakes a load, and on air loss the piston drifts. This model is discontinued; the current-production drop-in is ACEJ16X150, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X150-50 (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 ACEJ16X150-50 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 ACPJ16X150-50 Is Used
Fixture clamping on CNC pallets
The 100.5 N push at 0.5 MPa seats aluminium brackets into a drilling jig, and the 50 mm window lets one cylinder serve pallets of two different part heights between 100 and 150 mm of travel.
Packaging line reject pusher
A short body that is about 50% shorter in mounting length than an ISO 15552 profile cylinder fits beside a narrow conveyor frame, kicking light cartons sideways at 30-500 mm/s.
Sample press in a lab autosampler
The female M4x0.7 rod thread picks up a small pressing plate to apply about 60 N of usable force to vial caps, with the stop screw dialling the stroke down for shallow trays.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-50 with the ACEJ16X150-50
Size against neighbours: the 12 mm bore gives 56.5 N push at 0.5 MPa, while stepping up to 20 mm reaches 157.1 N - pick the 16 mm when you need roughly 100 N with an 8 mm rod. If the machine must hold position through a power cut, add an external locking unit, because the stop screw only sets the extend stroke and does not lock the piston. Order the -S version if you later want CMSE / DMSE switches; this code has no magnet. FA flange or LB foot mount on the standard face, and ACEJ16X150 is the current replacement to quote.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X150-50
- ✓ 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 ACPJ16X150-50 FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those figures rise to 140.7 N push and 105.6 N pull, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window, so the stop screw trims the 150 mm extend stroke down to any length from 100 to 150 mm. The 150 mm stroke is a made-to-order length, since the standard maximum for a 16 mm bore is 75 mm.
It is a short-body compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome rod, M5x0.8 ports and a fixed TPU bumper at both ends that only decelerates end of travel. This code has no magnet, so no switch can be read - order the -S variant to enable CMSE or DMSE switches. The model is discontinued; ACEJ16X150 is the current-production successor in the same bore, stroke and force class, so verify the ISO 21287 mounting dimensions before you swap.
