This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X100-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X100-40 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 ACPJ16X100-40
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X100-40 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 ACEJ16X100-40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X100-40
Double acting and adjustable, the ACPJ16X100-40 runs on a 16 mm bore with a 100 mm stroke trimmed by a 40 mm window: an external stop screw shortens the extend stroke anywhere in the 60-100 mm range. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, so as a rule of thumb plan on roughly 60 N of real work, which lifts about 5 kg vertically with a 2:1 margin. The 100 mm stroke exceeds the 75 mm standard limit for this bore, so it is a made-to-order build.
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 guarding where a full-length body cannot. A hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and the rod ends in a female M4x0.7 thread with M5x0.8 ports. Note: this model is discontinued - the current-production replacement is ACEJ16X100, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X100-40 (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 ACEJ16X100-40 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 ACPJ16X100-40 Is Used
Fixture clamping on a CNC jig
Trims the clamp stroke between 60 and 100 mm so a 100.5 N push seats aluminium housings against a hard stop without over-squeezing.
Carton reject pusher
The 60 N usable force at 0.5 MPa nudges misaligned cartons off a conveyor lane, with the 40 mm window tuned to lane width on site.
Small-parts ejector with sensing
Order the -S code and a CMSE switch flags end-of-stroke on a 100 mm eject move in an electronics assembly cell.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X100-40 with the ACEJ16X100-40
Size against the 0.5 MPa figures: bore 12 gives 56.5 N push and bore 20 gives 157.1 N, so the 16 mm bore at 100.5 N sits between them - step up if your fixture needs more than about 60 N of usable force. The stop screw only trims the extend stroke and is not a mid-stroke lock; on air loss the piston still drifts, so do not rely on it to hold a load. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and if you need position sensing, order the -S variant to add the optional magnet for CMSE / DMSE switches - this non-S code has no magnet. For new builds, specify ACEJ16X100 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X100-40
- ✓ 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 ACPJ16X100-40 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), speed 30-500 mm/s, and the 100 mm stroke is a made-to-order length since the bore's standard maximum is 75 mm.
A stop screw shortens the extend stroke by up to 40 mm, giving a usable 60-100 mm range; it is a mechanical end stop, not a load-holding brake. The ACPJ family is discontinued - order ACEJ16X100, the current ISO 21287 drop-in in the same bore, stroke and force class, and confirm its mounting dimensions before swapping.
