This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X100-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X100-20S 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 ACPJ16X100-20S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X100-20S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X100-20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X100-20S
Double acting and adjustable, the AirTAC ACPJ16X100-20S pushes 100.5 N (pull 75.4 N) at 0.5 MPa from a 16 mm bore, with a stop screw that trims the 100 mm extend stroke by up to 20 mm for an 80-100 mm working range. The 100 mm stroke exceeds the 75 mm maximum standard stroke for bore 16, so it is a made-to-order build. Its hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into shallow jigs and guarding where a full-length body will not fit.
The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped on for end-of-stroke signals. A fixed TPU bumper sits at both ends, the S45C hard-chrome rod carries a female M4x0.7 thread, and ports are M5x0.8. For sizing, treat roughly 60 N as the practical push budget at 0.5 MPa, which lifts about 6 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACEJ16X100, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X100-20S (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 ACEJ16X100-20S 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 ACPJ16X100-20S Is Used
Fixture clamping on CNC jigs
The 80-100 mm trim range lets one cylinder serve several fixture heights on a machining jig, with 100.5 N push at 0.5 MPa holding light parts against a hard stop.
Position feedback on assembly stations
With the -S magnet fitted, CMSE or DMSE switches confirm the rod has reached the trimmed extend position on a small electronics assembly line.
Ejector in compact packaging heads
The short body, about 50% shorter than an ISO 15552 profile cylinder, fits inside tight packaging machine frames to push 75.4 N on retract for tray ejection.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X100-20S with the ACEJ16X100-20S
Size between bores: a 12 mm bore gives 56.5 N push at 0.5 MPa, while a 20 mm bore reaches 157.1 N, so pick the 16 mm when your load sits between roughly 40 and 60 N of real work. The stop screw only shortens the extend stroke and is not a mid-stroke lock; on air loss the piston still drifts, so add a separate valve or clamp if you need holding. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. This unit is discontinued and the ACEJ16X100 is the current replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X100-20S
- ✓ 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 ACPJ16X100-20S FAQ
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, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window, so the stop screw trims the 100 mm extend stroke anywhere in an 80-100 mm range. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 100 mm stroke is a made-to-order length because the bore 16 standard maximum is 75 mm.
Order the ACEJ16X100, the current-production ISO 21287 successor: swap the P for an E and you get the same 16 mm bore, 100 mm stroke and force class with a matching short body and mounting family. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. The -S magnet on this model carries over as an option on the ACEJ, enabling CMSE / DMSE switches, and FA/FB flange or LB foot mountings bolt straight to the face.
