This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X150-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X150-20 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 ACPJ16X150-20
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-20 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 ACEJ16X150-20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-20
A double acting compact cylinder with an adjustable extend stroke, the ACPJ16X150-20 uses a 16 mm bore to deliver 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa. The -20 code adds a 20 mm adjustment window: a stop screw trims the 150 mm extend stroke down to 130 mm on site, so one cylinder covers a 130-150 mm range. Note this is a discontinued model; the current-production replacement is the ACEJ16X150 in the same bore, stroke and force class.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in slim jigs and guarded stations. The 150 mm stroke exceeds the 75 mm standard maximum for bore 16, so it is a made-to-order build. With the 100.5 N push figure, plan on roughly 60 N (about 6 kg) of usable vertical work at 0.5 MPa instead of the full rating. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper at each end, and an M4x0.7 female rod thread; the optional -S magnet enables CMSE / DMSE switches, and without -S no magnet is fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X150-20 (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 ACEJ16X150-20 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 ACPJ16X150-20 Is Used
Fixture clamp with trimmable stroke
On a small machining fixture, the 20 mm window lets a technician dial the 150 mm extend stroke down to 130 mm so the 100.5 N push seats the clamp exactly on the part.
Sensed part ejection on an assembly line
Ordered with the optional -S magnet, CMSE or DMSE switches confirm eject position in a compact assembly station where the short body fits beside neighboring tooling.
Carton push-off at a packing bench
The 130-150 mm adjustable range pushes lightweight cartons off a conveyor lane, with the fixed TPU bumper softening both ends at speeds from 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-20 with the ACEJ16X150-20
At 100.5 N push and 75.4 N pull at 0.5 MPa, bore 16 suits light clamping and part-presenting tasks; step down to bore 12 (56.5 N push) for tighter force budgets or up to bore 20 (157.1 N push) when the load grows. The stop screw only shortens the extend stroke and is not a mid-stroke lock, so the piston still drifts if air is lost. Match FA/FB flange or LB foot mounts and the I/Y rod knuckles to your fixture, order the -S code if CMSE / DMSE sensing is planned, and confirm ISO 21287 mounting dimensions before swapping to the ACEJ16X150 replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X150-20
- ✓ 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 ACPJ16X150-20 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, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window: the external stop screw shortens the 150 mm extend stroke to as little as 130 mm. It cannot lengthen the stroke past 150 mm, and the stop is not a load-holding brake. The 150 mm stroke is a made-to-order build since bore 16 tops out at 75 mm standard.
No - the ACPJ family is discontinued. The current-production drop-in is the ACEJ16X150, which matches the same 16 mm bore, 150 mm stroke and force class, but you should confirm the ISO 21287 mounting dimensions before swapping because the ACP was built to a DIN standard. Also note the port is M5x0.8, the rod thread is female M4x0.7, and position sensing requires the optional -S magnet with CMSE / DMSE switches.
