This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-40SB 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.
Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X160-40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40SB
This double acting ACPJ20X160-40SB is a DIN-standard compact adjustable-stroke cylinder with a 20 mm bore, 160 mm stroke and a 10 mm male-threaded rod. Air drives the piston both ways, and the -40 code gives a 40 mm adjustment window: a stop screw on the extend side trims the stroke anywhere within 120-160 mm, so one cylinder can serve several fixture depths. Push force is 157.1 N and pull 117.8 N at 0.5 MPa, rising to 219.9 N and 164.9 N at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The 160 mm stroke is longer than the 100 mm maximum standard stroke for this bore, so it is a made-to-order build.
The hard-anodized aluminium body is an ISO 21287 short design that saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight gantries and guarding where a full-length body cannot. Because the S code is on this unit, the magnet is fitted and CMSE or DMSE reed or solid-state switches can be mounted directly on the body. As a planning figure, treat roughly 0.6 of the push force as usable work, so about 94 N, which lifts roughly 9 kg vertically at 0.5 MPa with margin. Note that this ACPJ is discontinued: the current-production drop-in is ACEJ20X160, and you should confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-40SB (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.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40SB Is Used
Fixture clamping on CNC pallets
The 157.1 N push at 0.5 MPa suits clamping aluminium jigs on machining-centre pallets, and the 120-160 mm adjustment window lets one cylinder match several fixture heights.
Small-parts press-off ejector
With about 94 N of practical working force, the 20 mm bore ejects moulded caps or stamped blanks from a nest, while the fitted magnet drives CMSE switches to confirm full retract.
Packaging line gate pusher
The short ISO 21287 body fits inside conveyor guarding, and the male-threaded 10 mm rod takes a knuckle for pushing cartons between lane dividers at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40SB with the ACEJ20X160-40SB
Size against the load: at 0.5 MPa this bore pushes 157.1 N, while a 16 mm bore of the same family manages only 100.5 N and a larger 32 mm bore would be the next step up if you need more than about 200 N. Keep the stop screw as a stroke trim only - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost and a separate holding method is needed for suspended loads. FA/FB flanges and LB feet bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing. For new projects, order the ACEJ20X160 instead, as this ACPJ model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-40SB
- ✓ 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 ACPJ20X160-40SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa push is 219.9 N and pull 164.9 N. The theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s and temperature -20 to +70 C. The 160 mm stroke is made to order, since the bore 20 standard maximum is 100 mm.
The -40 code adds a stop screw that shortens the extend stroke by up to 40 mm, giving a usable range of 120-160 mm; it cannot lengthen the stroke past the ordered 160 mm. Fixed TPU bumpers decelerate at both ends. This ACPJ is discontinued, so the current drop-in is ACEJ20X160 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard.
