This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X20-10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X20-10SB 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 ACPJ16X20-10SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X20-10SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X20-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X20-10SB
Double acting and adjustable, the ACPJ16X20-10SB is a discontinued DIN-standard compact cylinder: 16 mm bore, 20 mm stroke with a 10 mm adjustment window, so an external stop screw trims the extend stroke anywhere between 10 and 20 mm on site. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa that rises to 140.7 N / 105.6 N, with a theoretical ceiling of 20.5 kgf at 1.0 MPa. 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.
The S code means the optional magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped straight onto the hard-anodized aluminium body, and the B code gives a male 8 mm rod thread. A practical sizing rule: about 60 N of that 100.5 N push is realistic working force at 0.5 MPa, which lifts roughly 6 kg vertically - halve it for a 2:1 margin and plan for about 3 kg. Note the stop screw is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts. For new builds, the current-production drop-in is the ACEJ16X20 - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X20-10SB (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 ACEJ16X20-10SB 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 ACPJ16X20-10SB Is Used
Small-parts ejection in plastic molding
A 10-20 mm trimmed extend stroke ejects finished clips or connectors from a compact mold nest, with the 100.5 N push at 0.5 MPa clearing parts up to about 6 kg of resisted drag.
Position-flagged test fixtures
Because the -S magnet is fitted, a CMSE switch on the body confirms clamp-made on an electronics test jig, while the stop screw dials the clamp travel between 10 and 20 mm.
Bench-top press and crimp station
The 140.7 N push at 0.7 MPa handles light crimping of wire terminals or pressing dowels into small housings, with the short body fitting under a low bench gantry.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X20-10SB with the ACEJ16X20-10SB
Size both ways: if 100.5 N at 0.5 MPa is marginal, step up to the 20 mm bore for 157.1 N; if the load is light, the 12 mm bore gives 56.5 N in the same short-body family. The 10 mm window suits fixtures where the stroke is finalized after installation - trim the extend stroke down from 20 mm, never past it. Match FA/FB flange or LB foot mounts and I/Y rod knuckles to the mounting face, and remember the male rod thread (B) here rather than the female default. This model is discontinued; order the ACEJ16X20 as the current replacement and verify ISO 21287 hole patterns first.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X20-10SB
- ✓ 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 ACPJ16X20-10SB 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. In practice plan on about 60 N of usable push at 0.5 MPa - roughly 6 kg vertical, or about 3 kg with a 2:1 safety margin. 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 -10 code sets a 10 mm adjustment window: a stop screw shortens the 20 mm extend stroke on site, giving a usable range of 10-20 mm, with fixed TPU bumpers at both ends. It is a mechanical end stop only - it never holds a load if air is lost. The ACPJ family is discontinued; the ACEJ16X20 is the current ISO 21287 drop-in in the same bore, stroke and force class, so confirm the mounting dimensions before swapping.
