This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X15-10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X15-10SB 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 ACPJ20X15-10SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X15-10SB 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 ACEJ20X15-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X15-10SB
This AirTAC ACPJ20X15-10SB is a double acting compact cylinder with an adjustable extend stroke: the -10 stop screw trims the 15 mm stroke down to as little as 5 mm on site, so one unit covers a 5-15 mm window. At 0.5 MPa the 20 mm bore delivers 157.1 N push and 117.8 N pull, rising to 219.9 N push at 0.7 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixture plates and guarding where a full-length body cannot.
The S code on this model means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped straight onto the hard-anodized aluminium body, and the B code gives a male 10 mm rod thread. For sizing, treat about 94 N (0.6 of the push force) as the realistic working output at 0.5 MPa, which lifts roughly 8 kg vertically with a 2:1 margin. Note that this ACPJ family 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 ACEJ20X15-10SB (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 ACEJ20X15-10SB 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 ACPJ20X15-10SB Is Used
Fixture clamp on a CNC jig
The 5-15 mm adjustable window lets a machinist dial the clamp stroke to the part, while 157.1 N push at 0.5 MPa holds aluminium housings against a locating pin during drilling.
Carton kick-off on a packing line
A short 15 mm stroke with TPU bumpers at both ends is enough to nudge cartons off a conveyor lane at 30-500 mm/s, and the fitted magnet feeds a CMSE switch to confirm each kick.
Presence check at a gate station
Because the -S magnet is fitted on this model, DMSE solid-state switches detect extend and retract on the hard-anodized body, giving PLC feedback in a guard-interlock slide that only has 15 mm of travel.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X15-10SB with the ACEJ20X15-10SB
At 157.1 N push (0.5 MPa) this 20 mm bore suits clamping and positioning jobs in the 90-95 N working range; step down to a 16 mm bore (100.5 N push) for lighter loads or up to the next frame size when you need more force at the same short length. The adjuster is a mechanical end stop for the extend stroke only - it does not lock the piston if air is lost, so add a separate holding valve for suspended loads. LB foot or FA/FB flange mounting, PT ports, male rod thread, and the fitted -S magnet for CMSE / DMSE switches round out the spec. Order the ACEJ20X15 as the current replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X15-10SB
- ✓ 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 ACPJ20X15-10SB 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. Plan on roughly 94 N of usable force at 0.5 MPa, which is about 8 kg of vertical lift with a 2:1 margin. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, air filtered to 40 um.
The -10 code is a 10 mm adjustment window: an external stop screw shortens the 15 mm extend stroke to any setting from 5 to 15 mm, so you can tune the stroke on the machine without swapping cylinders. It is a mechanical end stop only - it never holds a load if air pressure drops. The ACPJ family is discontinued; the current-production replacement is the ACEJ20X15 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
