This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X60-40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X60-40SB 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.

The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X60-40SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 60mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X60-40SB (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting adjustable-stroke compact cylinder, the ACPJ20X60-40SB uses a 20 mm bore to deliver 157.1 N push and 117.8 N pull at 0.5 MPa (219.9 N / 164.9 N at 0.7 MPa). Its -40 code gives a 40 mm adjustment window: an external stop screw trims the 60 mm extend stroke down to as little as 20 mm on site, so one cylinder covers a 20-60 mm working range. The S code means the optional -S magnet is fitted, ready for CMSE / DMSE reed or solid-state switches.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which suits tight jigs, guards and gantries. A hard-anodized aluminium body carries an S45C hard-chrome 10 mm rod with a male thread (B code), fixed TPU bumpers at both ends, and M5x0.8 ports. Plan on roughly 94 N (about 9.6 kgf) of real work at 0.5 MPa, or lift about 8 kg vertically with a 2:1 margin. Note: this model is discontinued; the current-production drop-in is ACEJ20X60, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X60-40SB (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.
| 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 ACEJ20X60-40SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| ACPJ | DIN compact cylinder (adjustable-stroke, discontinued). |
|---|---|
| 20 | Bore size in mm. |
| ×60 | Stroke length in mm. |
| -40 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (adjustable stroke).
The 20-60 mm trimmed extend range lets one cylinder clamp parts of varying heights on machining fixtures, with 157.1 N push at 0.5 MPa holding light workpieces.
With the fitted -S magnet, CMSE or DMSE switches confirm full extend or retract on a small parts ejector, while the stop screw sets the exact eject distance.
About 94 N of usable force at 0.5 MPa suits low-force crimping or marking of connectors and terminals in electronics and wire-harness benches.
Size by force: at 0.5 MPa the 20 mm bore pushes 157.1 N, while the 16 mm bore manages 100.5 N and the next step up would be a 25 mm class bore if you need more margin. The stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so do not treat it as a load-holding brake. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. For new projects order the ACEJ20X60, the current replacement in the same bore, stroke and force class.
Replacement checklist
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and the port is M5x0.8. The -40 window trims the 60 mm extend stroke to 20-60 mm.
A stop screw on the head shortens the extend stroke by up to 40 mm within the ordered window, giving a usable 20-60 mm range; it cannot lengthen the stroke past 60 mm. The ACPJ family is discontinued, and the current-production drop-in is ACEJ20X60 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
