This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X150-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X150-40 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 ACPJ16X150-40
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-40 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X150-40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-40
Double acting compact cylinder with an adjustable extend stroke, the ACPJ16X150-40 uses a 40 mm stop-screw window so the effective stroke can be trimmed anywhere between 110 and 150 mm on site. At 0.5 MPa the 16 mm bore delivers 100.5 N push and 75.4 N pull, rising to 140.7 N push at 0.7 MPa. The 150 mm stroke is longer than the 75 mm standard limit for bore 16, so it is a made-to-order build. Note this model is discontinued; the current-production replacement is ACEJ16X150, same bore, stroke and force class.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters in slim gantries and guarded cells. A practical sizing rule: keep real work to about 60 N (roughly 6 kgf) at 0.5 MPa, enough to lift about 5 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome rod, a female M4x0.7 rod thread and fixed TPU bumpers at both ends; the magnet is the optional -S code, so this unit has none and no CMSE / DMSE switch can be fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X150-40 (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 ACEJ16X150-40 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 ACPJ16X150-40 Is Used
Fixture clamp with trimmed throw
A 40 mm window lets a jig builder set the exact clamp position between 110 and 150 mm, using the 100.5 N push at 0.5 MPa to seat small aluminium parts against a nest.
Packaging line ejector
At 30-500 mm/s the rod can push lightweight cartons off a belt; the compact body fits the narrow frame space an ISO 15552 profile cylinder cannot.
Lab feed station
The female M4x0.7 rod thread accepts small tooling for dosing or sample indexing, with the 6 kgf usable force matching light vials and trays.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-40 with the ACEJ16X150-40
Size between bores: the 12 mm ACPJ12 gives 56.5 N push at 0.5 MPa, while the 20 mm ACPJ20 reaches 157.1 N, so the 16 mm at 100.5 N sits mid-range for light clamping and indexing. Remember the stop screw trims the extend stroke only and is not a mid-stroke lock - on air loss the rod still drifts. FA/FB flange and LB foot mountings bolt to the standard face. Order the -S variant if position sensing via CMSE / DMSE switches is needed. For new designs specify ACEJ16X150 and confirm ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X150-40
- ✓ 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 ACPJ16X150-40 FAQ
At 0.5 MPa: 100.5 N push and 75.4 N pull. 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), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um.
The -40 code gives a 40 mm window: an external stop screw shortens the 150 mm extend stroke to as little as 110 mm; it cannot lengthen it. Fixed TPU bumpers decelerate at both ends. The ACPJ family is discontinued - order ACEJ16X150 as the drop-in successor and confirm ISO 21287 mounting dimensions first.
