This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X15-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X15-10S 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 ACPJ20X15-10S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X15-10S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X15-10S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X15-10S
Double acting and adjustable, the ACPJ20X15-10S is a discontinued DIN-standard compact cylinder with a 20 mm bore, a 15 mm stroke and a 10 mm trim window: an external stop screw shortens the extend stroke on site to anywhere between 5 and 15 mm. Push force is 157.1 N at 0.5 MPa (219.9 N at 0.7 MPa), and the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped jigs and guarding where a full-length body will not fit.
The -S code on this model means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the hard-anodized aluminium body. For sizing, plan on about 94 N of real work at 0.5 MPa (roughly 0.6 of the push rating), which lifts about 8 kg vertically with a 2:1 margin. This model is discontinued; the current-production drop-in is the ACEJ20X15, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X15-10S (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 ACEJ20X15-10S 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 ACPJ20X15-10S Is Used
Small-parts ejection on assembly fixtures
The 157.1 N push at 0.5 MPa kicks finished bushings or terminals off a nest, and the 5-15 mm trimmed stroke keeps the ejector pin travel exactly where the fixture needs it.
Position-verified clamping in test rigs
With the fitted -S magnet and a CMSE switch, the PLC confirms the clamp has reached the trimmed stop before a leak test starts on automotive hose assemblies.
Crimp and press-fit of connector housings
About 94 N of usable force at 0.5 MPa presses ribbon-cable connectors into PCB housings, and the 30-500 mm/s speed range lets the cycle be tuned per part.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X15-10S with the ACEJ20X15-10S
At 20 mm bore this sits in the middle of the ACPJ range: the 16 mm bore delivers 100.5 N push at 0.5 MPa while the next step up, a 32 mm bore, reaches around 482 N, so drop to 16 for light clamping or step up if 157.1 N at 0.5 MPa is marginal. The stop screw trims the extend stroke only within the ordered 10 mm window and never lengthens it past 15 mm, and it is a mechanical end stop, not a mid-stroke lock, so the rod can still drift on air loss. FA/FB flanges and LB feet bolt to the same face, and the fitted -S magnet accepts CMSE / DMSE switches. Order the ACEJ20X15 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X15-10S
- ✓ 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 ACPJ20X15-10S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa that rises to 219.9 N push and 164.9 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. The -10 code gives a 10 mm adjustment window, so the stop screw trims the 15 mm extend stroke down to as little as 5 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed is 30-500 mm/s, and the port is M5x0.8.
No, the ACPJ20X15-10S is discontinued. The current-production replacement is the ACEJ20X15, which swaps the P for an E and matches the same 20 mm bore, 15 mm stroke and force class in an ISO 21287 compact body. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping, and re-order the -S magnet code if you need CMSE / DMSE switch sensing.
