This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X20-10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X20-10SB 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 ACPJ12X20-10SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X20-10SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm 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 ACEJ12X20-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X20-10SB
This is a double acting, adjustable-stroke compact cylinder from AirTAC's discontinued ACPJ range, built to the DIN-standard short-body format with a hard-anodized aluminium body and an S45C hard-chrome rod. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N push at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures where a full-length body cannot.
The -10 code gives a 10 mm adjustment window: a stop screw trims the 20 mm extend stroke down to as little as 10 mm on site, so the usable range is 10-20 mm. As a working rule, plan on about 34 N of real work at 0.5 MPa (roughly 60% of the push rating), which corresponds to lifting about 3 kg vertically with a 2:1 margin. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing. The model is discontinued; the current-production replacement is the ACEJ12X20, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X20-10SB (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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACEJ12X20-10SB 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 ACPJ12X20-10SB Is Used
Small-part ejection on assembly jigs
The trimmed 10-20 mm extend range ejects finished micro-components from a fixture pocket without overshoot, using 56.5 N of push at 0.5 MPa.
Position-verified clamping in test rigs
With the -S magnet fitted, CMSE or DMSE switches confirm the clamped position on an electronics test bench, while the stop screw sets exact clamp travel.
Compact press-fit of connectors
About 3 kg of vertical working force with margin suits light press-fit of terminals and connectors inside tight machine guards where a long body will not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X20-10SB with the ACEJ12X20-10SB
Size the load against 56.5 N push at 0.5 MPa: if the task needs more, step up to the 16 mm bore (100.5 N push at 0.5 MPa); if less, the same bore with a shorter adjustment window may suit. Remember the stop screw only trims the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. The male rod thread (B code) suits external knuckles, and FA flange or LB foot mounts bolt to the ISO 21287 face. This model is discontinued; order the ACEJ12X20 as the drop-in successor and verify mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X20-10SB
- ✓ 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 ACPJ12X20-10SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window, so the stop screw trims the 20 mm extend stroke anywhere between 10 and 20 mm. Speed range is 30-500 mm/s and operating pressure is 0.15-1.0 MPa (22-145 psi).
No - the ACPJ family is discontinued. The current-production replacement is the ACEJ12X20 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class with the same FA/LB mounting family and optional magnet for CMSE / DMSE switches. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping.
