This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-30SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-30SB 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 ACPJ20X110-30SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X110-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30SB
Double acting and adjustable, the ACPJ20X110-30SB is a discontinued DIN-standard compact cylinder with a 20 mm bore, 110 mm made-to-order stroke and a 30 mm trim window: a stop screw shortens the extend stroke anywhere in the 80-110 mm range. It pushes 157.1 N and pulls 117.8 N at 0.5 MPa, rising to 219.9 N at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The male rod thread (B code) and the -S magnet are both on this unit, so CMSE or DMSE switches can be fitted for end-position sensing.
The hard-anodized aluminium body with an S45C hard-chrome rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into cramped jigs and guarding. At 0.5 MPa the push force works out to about 16 kgf, so plan on lifting roughly 8 kg vertically with a 2:1 margin - enough for small fixtures and light part transfer. Note the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it never holds a load. For new builds, the current-production drop-in is the ACEJ20X110; confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-30SB (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 ACEJ20X110-30SB 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 ACPJ20X110-30SB Is Used
Ejector on a small assembly jig
The 80-110 mm trim range lets a fixture builder dial in the exact ejection travel for stamped terminals, with 157.1 N at 0.5 MPa clearing parts reliably.
Carton hold-down on a packing bench
A 20 mm bore pressing about 16 kgf holds flaps during taping, and the male rod thread takes a knuckle for a swing pad.
Gated clamp with position feedback
Because the -S magnet is fitted, CMSE or DMSE switches report clamp-open and clamp-closed on a rotary indexing table without extra brackets.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-30SB with the ACEJ20X110-30SB
Size both ways: if 157.1 N at 0.5 MPa is more than the job needs, the 16 mm bore delivers 100.5 N in the same short body; if 219.9 N at 0.7 MPa is marginal, step up to the next force class. The 110 mm stroke exceeds the 100 mm standard maximum for bore 20, so it is made to order - lead time applies. FA/FB flanges, LB feet and I/Y rod knuckles bolt to the face, and the -S magnet on this model accepts CMSE / DMSE switches. This ACPJ is discontinued; the ACEJ20X110 is the current replacement - verify ISO 21287 hole patterns before ordering.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-30SB
- ✓ 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 ACPJ20X110-30SB 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. The -30 code gives a 30 mm adjustment window, so the extend stroke is trimmed anywhere between 80 and 110 mm with the stop screw. The 110 mm stroke is above the 100 mm standard limit for bore 20, so it is made to order. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the rod end is male thread.
The hard-anodized aluminium body is a short ISO 21287-class design that saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and M5x0.8 ports. The ACPJ family is no longer in production: the current drop-in is the ACEJ20X110, which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP follows the older DIN-standard footprint.
