This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X75-75SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X75-75SB 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 ACPJ12X75-75SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X75-75SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X75-75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X75-75SB
The ACPJ12X75-75SB is a double acting compact cylinder with an adjustable stroke: an external stop screw trims the extend stroke anywhere within the ordered 75 mm window, giving a usable range of 0-75 mm. 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. A practical rule of thumb is to plan for about 60% of the rated push, so roughly 34 N (about 3.4 kgf) of real work at 0.5 MPa.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarding where a full-length body cannot. The 75 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so this unit is a made-to-order build. Note that the model is discontinued; the current-production replacement is ACEJ12X75, and buyers should confirm ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X75-75SB (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 ACEJ12X75-75SB 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 ACPJ12X75-75SB Is Used
Position-confirmed ejector on small assembly stations
The fitted magnet plus a CMSE switch confirms the trimmed extend position before the next cycle starts, useful on pick-and-place heads where the 0-75 mm adjustable window lets one cylinder serve several part heights.
Micro press-fit of connector pins
About 56.5 N of push at 0.5 MPa is enough to seat small PCB connectors and pins, and the stop screw sets the seating depth precisely within the 75 mm window.
Sample lift in compact lab automation
With a 2:1 margin the rod lifts about 2.9 kg vertically, so microplate stacks and small sample carriers can be raised in tight analyser frames where a short body is mandatory.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X75-75SB with the ACEJ12X75-75SB
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa versus 100.5 N for the 16 mm and 157.1 N for the 20 mm. If your part weight or clamping need sits near 34 N of working force, this size fits; step up to ACPJ16X75-75 if you need more margin. The male rod thread (B code) suits external knuckles, and the fitted -S magnet accepts CMSE / DMSE switches for end-position sensing. The stop screw adjusts the extend stroke only and is not a mid-stroke lock, so the piston still drifts on air loss. Order ACEJ12X75 as the current drop-in replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X75-75SB
- ✓ 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 ACPJ12X75-75SB 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; theoretical maximum is 11.5 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: a stop screw shortens the 75 mm extend stroke by up to 75 mm, so the usable range is 0-75 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s. The 75 mm stroke is a made-to-order build because the bore 12 maximum standard stroke is 50 mm.
An external stop screw mechanically limits the extend stroke anywhere within the 75 mm window; it shortens the stroke only and never lengthens it past the ordered stroke. It is an end stop, not a load-holding brake, so the piston still drifts if air is lost. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-position detection. The unit is discontinued; ACEJ12X75 is the current replacement, so confirm ISO 21287 mounting dimensions before ordering.
