This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X70-75B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X70-75B 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 ACPJ16X70-75B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-75B 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 ACEJ16X70-75B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-75B
Double acting and adjustable, the ACPJ16X70-75B trims its extend stroke on site with an external stop screw: the -75 code sets a 75 mm window, so the usable extend range runs from 0 up to the full 70 mm stroke. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those figures rise to 140.7 N and 105.6 N. The male rod thread (B code) bolts straight to I/Y knuckles. Note this model is discontinued - the current-production drop-in is the ACEJ16X70, so confirm ISO 21287 mounting dimensions before swapping.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body cannot. A fixed TPU bumper sits at both ends and simply decelerates the piston - it never locks or brakes a load, and on air loss the piston still drifts. For sizing, plan on roughly 60 N of real work at 0.5 MPa (about 0.6 of the push rating), which is a vertical lift of about 5 kg - halve that to roughly 2.5 kg for a 2:1 margin. No magnet is fitted on this version; order the -S code to enable CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X70-75B (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 ACEJ16X70-75B 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 ACPJ16X70-75B Is Used
Bench-top press fixture
The 100.5 N push at 0.5 MPa is enough to seat small terminals or dowel pins in electronics assembly, and the 0-70 mm adjustable range lets one cylinder serve several part heights.
Compact jig clamping
With about 50% of the mounting length of an ISO 15552 profile cylinder, this 16 mm bore clamps aluminium machined parts inside dense drilling jigs where space is scarce.
Gantry eject with position check
Order the -S magnet version and add CMSE / DMSE switches to confirm part ejection on a pick-and-place gantry; the male rod thread takes a knuckle directly.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-75B with the ACEJ16X70-75B
At 16 mm bore this sits mid-range: the 12 mm bore gives 56.5 N push at 0.5 MPa for lighter clamping, while the 20 mm bore reaches 157.1 N when you need more force in the same short envelope. The 70 mm stroke is within the 75 mm maximum standard stroke for bore 16, so no made-to-order build is required. Match FA/FB flange or LB foot mounts to the ISO 21287 face, and remember the stop screw shortens the extend stroke only - it is not a mid-stroke lock. Since ACPJ is discontinued, order the ACEJ16X70 as the current replacement and verify mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X70-75B
- ✓ 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 ACPJ16X70-75B 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; theoretical maximum is 20.5 kgf at 1.0 MPa. The -75 code gives a 75 mm adjustment window, so the stop screw can trim the 70 mm extend stroke anywhere from 0 to 70 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, rod 8 mm with male thread.
It is a short ISO 21287-class compact cylinder with a hard-anodized aluminium body, S45C hard-chrome rod and a fixed TPU bumper at both ends that only decelerates - it never holds a load. FA/FB flange and LB foot mounts bolt to the standard face. Switches are CMSE / DMSE, but only when you order the optional -S magnet; this B-code version has no magnet fitted. The model is discontinued, so specify the ACEJ16X70 replacement and confirm ISO 21287 dimensions.
