This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X70-10B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X70-10B 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 ACPJ16X70-10B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-10B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X70-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-10B
Double acting and adjustable, the ACPJ16X70-10B is a discontinued DIN-standard compact cylinder with a 16 mm bore and 70 mm stroke. A stop screw trims the extend stroke by up to 10 mm on site, giving a usable 60-70 mm range, and a fixed TPU bumper sits at both ends. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa that rises to 140.7 N push and 105.6 N pull. 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 cannot.
The hard-anodized aluminium body carries an S45C hard-chrome rod with a male (B code) thread, and air ports are M5x0.8. Plan on about 60 N of real work at 0.5 MPa (0.6 x the 100.5 N push), which lifts roughly 6 kg vertically, or about 3 kg with a 2:1 margin. This model is discontinued: order the current ACEJ16X70, a drop-in successor in the same bore, stroke and force class, and confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X70-10B (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 ACEJ16X70-10B 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 ACPJ16X70-10B Is Used
Small-part ejection from fixtures
The 100.5 N push at 0.5 MPa is enough to kick machined aluminium or plastic parts off a CNC jig, and the 10 mm trim lets you tune the extend stroke to the part pocket without re-gapping the mount.
Light clamping on electronics assembly benches
With about 60 N of usable force at 0.5 MPa, the cylinder holds PCB trays or connector housings during screwdriving, and the compact body fits inside bench-top guarding where longer bodies will not.
Indexing slides on packaging micro-machines
Running at 30-500 mm/s, the 60-70 mm adjustable range advances small cartons or blisters between stations; order the -S magnet option if you later need CMSE or DMSE position switches.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-10B with the ACEJ16X70-10B
At 16 mm bore you sit mid-range: the 12 mm bore gives 56.5 N push at 0.5 MPa, while the 20 mm bore reaches 157.1 N, so step up if your part or fixture mass approaches the 6 kg vertical-lift equivalent. The 70 mm stroke is within the 75 mm maximum standard stroke for this bore, so no made-to-order build is needed. Mounting uses FA/FB flanges or LB feet, and the male rod thread suits knuckle brackets. Note the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a load-holding lock. No magnet is fitted on this code; if you need CMSE or DMSE switches, order the -S version or move to the current ACEJ16X70.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X70-10B
- ✓ 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 ACPJ16X70-10B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: a stop screw shortens the 70 mm extend stroke by up to 10 mm, so the working range is 60-70 mm. It cannot lengthen the stroke past 70 mm, and the stop is not a mid-stroke lock. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
No, the ACPJ16X70-10B is discontinued. The current-production replacement is the ACEJ16X70 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. It is a drop-in successor, but because the ACP is DIN-standard you should confirm the ISO 21287 mounting dimensions before swapping. The replacement keeps the M5x0.8 port, the 8 mm rod and the FA/FB and LB mounting family, and the magnet remains an optional -S code for CMSE / DMSE switches.
