This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X90-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X90-50S 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 ACPJ16X90-50S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-50S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X90-50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-50S
The ACPJ16X90-50S is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 90 mm stroke by up to 50 mm, giving a usable range of 40-90 mm on site. Air pushes the rod out and pulls it back, and a fixed TPU bumper decelerates the piston at both ends. At 0.5 MPa this 16 mm bore delivers 100.5 N push and 75.4 N pull; at 0.7 MPa that rises to 140.7 N push. In practice, plan on roughly 60 N of usable work at 0.5 MPa, which is about 3 kg lifted vertically with a 2:1 margin.
Note that the 90 mm stroke exceeds the 75 mm standard maximum for the 16 mm bore, so this unit is made to order. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. 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 replacement is the ACEJ16X90, a drop-in in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X90-50S (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 ACEJ16X90-50S 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 ACPJ16X90-50S Is Used
Carton ejector on a case packer
The 40-90 mm trim range lets one cylinder eject cartons of different depths; 100.5 N push at 0.5 MPa is enough for light corrugated cases.
Part present sensor on a CNC fixture
With the -S magnet fitted, a CMSE switch signals full extension of the 8 mm rod before the machining cycle starts.
Label press on a bottling line
The short body, about 50% shorter than an ISO 15552 profile cylinder, fits inside the guard where space is tight, and the stop screw sets press depth per bottle size.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-50S with the ACEJ16X90-50S
Size against the load: at 0.5 MPa the 16 mm bore gives 100.5 N push. If your tooling needs more, step up to the 20 mm bore (157.1 N push at 0.5 MPa); for lighter clamping, the 12 mm bore offers 56.5 N. The 50 mm window suits machines where one cylinder must serve several product lengths - set the stop screw once and the extend stroke lands anywhere from 40 to 90 mm. FA/FB flange and LB foot mounts bolt to the standard face, and I/Y rod knuckles fit the M4x0.7 female rod thread. The stop is a mechanical end stop only: on air loss the piston still drifts, so do not rely on it to hold a load mid-stroke. Order the ACEJ16X90 as the current replacement and verify mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X90-50S
- ✓ 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 ACPJ16X90-50S FAQ
Push is 100.5 N and pull 75.4 N at 0.5 MPa; at 0.7 MPa push is 140.7 N and pull 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) of air filtered to 40 um, proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C. Port is M5x0.8 and the rod thread is female M4x0.7. The 90 mm stroke is a made-to-order length above the 75 mm standard maximum for this bore.
The -50 code is a 50 mm window: an external stop screw shortens the 90 mm extend stroke down to 40 mm, so you can dial in the exact end position without changing cylinders. It is a mechanical stop for the extend direction only and never holds a load against air loss. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount on the body for end-of-stroke detection. Since the ACPJ is discontinued, order the ACEJ16X90 as the current drop-in and confirm ISO 21287 mounting dimensions before the swap.
