This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X10-10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X10-10SB 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 ACPJ20X10-10SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X10-10SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 10mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X10-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X10-10SB
The ACPJ20X10-10SB is a double acting, adjustable-stroke compact cylinder with a 20 mm bore and a short 10 mm stroke that an external stop screw trims anywhere in a 10 mm window, so the usable extend range is 0-10 mm. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N on the extend side at 0.7 MPa. The B code gives a male rod thread on the 10 mm rod, and 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.
This is a discontinued DIN-standard compact unit, not a current-production line item: the drop-in successor is the ACEJ20X10 in the ISO 21287 family, which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP series follows the older DIN footprint. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarded stations. For sizing, treat roughly 0.6 of the push force as usable, so about 94 N of real work at 0.5 MPa, or roughly 8 kg of vertical lift with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X10-10SB (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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
The ACEJ20X10-10SB 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 ACPJ20X10-10SB Is Used
Micro press ejection
A 10 mm extend stroke trimmed by the stop screw ejects finished watch or connector parts from a die, with 157.1 N of push at 0.5 MPa enough for shallow pockets.
Switched clamp check
Because the S magnet is fitted, a CMSE switch on the body confirms the rod is fully forward before a small PCB test fixture releases its guard.
Bottle-capping punch
In a cosmetics line, the male-threaded 10 mm rod drives a short crimp punch over a 0-10 mm range, cycling at 30-500 mm/s between TPU-bumpered ends.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X10-10SB with the ACEJ20X10-10SB
At 157.1 N push at 0.5 MPa this 20 mm bore sits mid-range: step down to a 16 mm bore (100.5 N push) for lighter pick-and-place, or up to a 25 mm class bore when you need more margin. The 10 mm adjustment window only shortens the extend stroke, and the stop is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. FA/FB flange and LB foot mountings plus I/Y rod knuckles bolt to the face. If you are specifying new equipment, order the ACEJ20X10 instead, and verify the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X10-10SB
- ✓ 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 ACPJ20X10-10SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N; theoretical maximum is 32 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: a stop screw on the extend side shortens the 10 mm stroke on site, giving a usable range of 0-10 mm. It runs double acting on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, at 30-500 mm/s, with a fixed TPU bumper at both ends.
No, the ACPJ family is discontinued. The current-production replacement is the ACEJ20X10, an ISO 21287 compact cylinder in the same bore, stroke and force class with a matching short body and mounting family. Because the ACP series is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before ordering the swap. This unit carries the optional -S magnet, so CMSE / DMSE switches work on it; the ACEJ equivalent should be ordered with the S code if sensing is needed.
