This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X125-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X125-100 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 ACPJ16X125-100
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X125-100 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 ACEJ16X125-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X125-100
Double acting and adjustable, the ACPJ16X125-100 is a DIN-standard compact cylinder with a 16 mm bore and a 125 mm stroke that a stop screw can trim by up to 100 mm, giving a usable extend range of 25-125 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 125 mm stroke is longer than the 75 mm standard maximum for this bore, so it is a made-to-order build. This model is discontinued - the current-production replacement is the ACEJ16X125, and buyers should confirm ISO 21287 mounting dimensions before swapping.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding. For sizing, treat roughly 60 N as the practical working force at 0.5 MPa, which lifts about 6 kg vertically - and halve that for a 2:1 margin on real part weight. FA/FB flanges and LB feet bolt to the ISO 21287 face, and the fixed TPU bumpers at both ends simply decelerate the rod; they never hold a load. Note there is no magnet fitted, so position switches cannot be used unless the optional -S magnet is ordered.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X125-100 (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 ACEJ16X125-100 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 ACPJ16X125-100 Is Used
Fixture clamp with trimmable reach
On a small CNC jig, the 100 mm window lets one ACPJ16X125-100 clamp parts of varying depth; its 100.5 N push at 0.5 MPa suits light clamping of aluminium brackets.
Ejector on a compact indexing dial
The short body fits under a dial-plate guard where a full-length cylinder will not, and the 25-125 mm extend range handles part ejection once the -S magnet and a CMSE switch are ordered.
Small carton push-off station
Pushing lightweight cartons off a benchtop conveyor, the 16 mm bore delivers about 6 kg of vertical-lift equivalent at 0.5 MPa, with the stop screw set to the exact throw needed.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X125-100 with the ACEJ16X125-100
At 16 mm bore this sits between the 12 mm (56.5 N push at 0.5 MPa) and 20 mm (157.1 N push at 0.5 MPa) sizes, so pick up or down based on the 100.5 N push figure. The 100 mm adjustment window means one cylinder can serve several fixture variants, but remember the stop only shortens the extend stroke - it is not a mid-stroke lock, and on air loss the piston drifts. If you need reed or solid-state sensing with CMSE / DMSE switches, order the -S code, since this version has no magnet. FA/FB flange and LB foot mountings match the ISO 21287 face. For new projects, specify the ACEJ16X125 instead, as the ACPJ is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X125-100
- ✓ 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 ACPJ16X125-100 FAQ
It is double acting: push 100.5 N and pull 75.4 N at 0.5 MPa, push 140.7 N and pull 105.6 N at 0.7 MPa, with a theoretical maximum of 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, and the port is M5x0.8 with an M4x0.7 female rod thread. The 125 mm stroke is a made-to-order length above the 75 mm standard maximum for bore 16.
The -100 code gives a 100 mm adjustment window: an external stop screw shortens the 125 mm extend stroke on site, so the usable range is 25-125 mm. The fixed TPU bumpers at each end only decelerate the rod near the ends and never lock or hold a load. The ACPJ family is discontinued; the current drop-in is the ACEJ16X125 (same bore, stroke and force class), and you should confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
