This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-50SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-50SB 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 ACPJ20X160-50SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50SB 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 ACEJ20X160-50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50SB
Double acting compact cylinder with an adjustable extend stroke, the ACPJ20X160-50SB carries a 20 mm bore and a 160 mm stroke trimmed by a 50 mm stop-screw window, so the usable extend range is 110-160 mm. The stop is a mechanical end stop only: it shortens the stroke on site, it never locks or holds a load if air is lost. At 0.5 MPa this bore pushes 157.1 N and pulls 117.8 N; a practical rule of thumb is to plan about 94 N (roughly 9.6 kg) of real work, which lifts about 4.8 kg vertically with a 2:1 margin. The 160 mm stroke exceeds the 100 mm maximum standard stroke for bore 20, so this unit is a made-to-order build.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight gantries and guarding where a full-length body will not fit. A hard-anodized aluminium body runs on an S45C hard-chrome rod, fixed TPU bumpers decelerate both ends, and the fitted -S magnet accepts CMSE / DMSE switches. Note: the ACPJ family is discontinued - the current-production drop-in is ACEJ20X160, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-50SB (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 ACEJ20X160-50SB 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 ACPJ20X160-50SB Is Used
Small-parts ejection on assembly fixtures
The 157.1 N push at 0.5 MPa ejects stamped terminals or molded inserts from a jig, with the 50 mm window letting you dial the extend stroke between 110 and 160 mm to match each die.
Position-verified clamping in test rigs
With the fitted -S magnet driving CMSE or DMSE switches, a bench-top leak or functional tester confirms the 20 mm bore ram has reached the trimmed stop before the cycle continues.
Light vertical lift-and-lower in gantries
Lifts about 4.8 kg vertically with a 2:1 margin, so it raises sensor heads or small pallets in compact pick stations where the short body saves roughly half the length of an ISO 15552 profile cylinder.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50SB with the ACEJ20X160-50SB
Size the job both ways: bore 16 gives 100.5 N push at 0.5 MPa if your load is lighter, while bore 20 delivers 157.1 N push and 117.8 N pull - step up if you need more force than that at 0.5 MPa. The male rod thread (B code) suits external knuckles and tooling, and FA/FB flange or LB foot mounts bolt to the standard face. If you need position feedback, this model already carries the optional -S magnet for CMSE / DMSE switches. Because ACPJ is discontinued, order ACEJ20X160 as the current equivalent and verify ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-50SB
- ✓ 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 ACPJ20X160-50SB FAQ
Bore 20 mm, stroke 160 mm (made to order, above the 100 mm standard maximum for this bore), 50 mm adjustment window. Push 157.1 N and pull 117.8 N at 0.5 MPa; push 219.9 N and pull 164.9 N at 0.7 MPa; theoretical maximum 32 kgf at 1.0 MPa. Operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, male rod thread, fixed TPU bumpers both ends.
Order ACEJ20X160: swap the P for an E and you get the current-production ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ACPJ follows a DIN-standard layout, confirm the ISO 21287 mounting dimensions (FA/FB flange or LB foot faces) before committing the swap.
