This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X125-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X125-75S 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 ACPJ16X125-75S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X125-75S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X125-75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X125-75S
Double acting compact cylinder with an adjustable extend stroke, the ACPJ16X125-75S carries a 16 mm bore and a 125 mm stroke trimmed by a 75 mm stop-screw window, giving a usable range of 50-125 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. Note that the 125 mm stroke exceeds the 75 mm maximum standard stroke for this bore, so it is a made-to-order item.
In practice, plan on about 60 N of real work at 0.5 MPa (roughly 60% of the push rating), which corresponds to lifting about 6 kg vertically - halve that to around 3 kg if you want a 2:1 margin when raising a fixture or part. The -S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly. The ACPJ family is discontinued; the current-production drop-in is the ACEJ16X125, and buyers should confirm ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X125-75S (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 ACEJ16X125-75S 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 ACPJ16X125-75S Is Used
Fixture clamp with trimmed stroke
A 75 mm adjustment window lets a jig builder dial the 125 mm extend stroke down to 50-125 mm on a drilling fixture, with the 100.5 N push at 0.5 MPa suiting light clamping of aluminium brackets.
Position-verified ejector
Because the -S magnet is fitted, CMSE or DMSE switches confirm extend and retract on a small electronics-assembly ejector running at 30-500 mm/s, without adding an external stroke sensor.
Compact press assist
The short body, about 50% shorter in mounting length than an ISO 15552 profile cylinder, fits inside a benchtop labelling head where 140.7 N push at 0.7 MPa seats labels or snaps small caps.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X125-75S with the ACEJ16X125-75S
Size this bore both ways: the 12 mm bore delivers 56.5 N push at 0.5 MPa, while stepping up to the 20 mm bore gives 157.1 N - so the 16 mm at 100.5 N sits in the middle for light clamping and indexing. The stop screw only shortens the extend stroke within the 75 mm window; it is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost. Mounting options include FA/FB flanges and LB feet, plus I/Y rod knuckles. Since this model is discontinued, order the ACEJ16X125 as the current replacement and verify the mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X125-75S
- ✓ 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 ACPJ16X125-75S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa, 140.7 N push and 105.6 N pull; theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um, port M5x0.8, rod 8 mm with female M4x0.7 thread, and a fixed TPU bumper at both ends.
The -75 code sets a 75 mm window: an external stop screw shortens the 125 mm extend stroke on site, so the working range is 50-125 mm - it trims the stroke, it never extends it past the ordered value. The ACPJ family is discontinued; the current-production drop-in is the ACEJ16X125 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP was DIN-standard.
