This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X100-30SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X100-30SB 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 ACPJ20X100-30SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-30SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X100-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-30SB
Double acting with an adjustable extend stroke, the ACPJ20X100-30SB is a discontinued DIN-standard compact cylinder: 20 mm bore, 100 mm stroke and a 30 mm trim window, so a stop screw sets any usable extend stroke from 70 to 100 mm on site. 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 32 kgf at 1.0 MPa. The male rod thread (B code) suits knuckle fittings, and the -S magnet this model carries accepts CMSE / DMSE switches for end-of-stroke sensing.
The hard-anodized aluminium body with S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into cramped fixture plates and guarding frames. In practice, plan on roughly 94 N of real work at 0.5 MPa (about 0.6 of the rated push), and for vertical lifts that means it raises about 8 kg with a 2:1 margin. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends. This model is discontinued: the current-production replacement is the ACEJ20X100, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X100-30SB (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 ACEJ20X100-30SB 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 ACPJ20X100-30SB Is Used
Fixture clamp with trimmed stroke
On a CNC jig plate, the 30 mm window lets one cylinder serve parts needing 70-100 mm of clamp travel, with 157.1 N push at 0.5 MPa holding steel blocks against a hard stop.
Packaging line push-off arm
At a carton diverter, the male rod thread drives a knuckled pusher that sweeps boxes off a belt in the 70-100 mm range, while the -S magnet and a DMSE switch confirm retract between cycles.
Small parts lift in a test rig
A lab indexing table weighing about 8 kg is raised vertically within the 2:1 margin of this bore's 157.1 N push, with the short body fitting under the rig's low top plate.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-30SB with the ACEJ20X100-30SB
Size both ways before ordering: the 16 mm bore pushes 100.5 N at 0.5 MPa, while the 25 mm class steps up well above this 20 mm bore's 157.1 N, so pick by load plus the 70-100 mm adjustable range. Remember the stop screw only trims the extend stroke and is not a mid-stroke lock; on air loss the piston still drifts, so add external stops or a valve for holding. FA/FB flanges and LB feet bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position. Since ACPJ is discontinued, order the ACEJ20X100 as the drop-in successor and verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X100-30SB
- ✓ 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 ACPJ20X100-30SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa, 219.9 N push and 164.9 N pull; theoretical maximum is 32 kgf at 1.0 MPa. For sizing, count on about 94 N of usable work at 0.5 MPa, which is roughly an 8 kg vertical lift with a 2:1 margin. The 30 mm stop screw trims the 100 mm extend stroke down to 70 mm but never holds a load on air loss.
No, the ACPJ family is discontinued; the current-production drop-in is the ACEJ20X100 in the same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping. The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fixed TPU bumpers decelerate both ends, FA/FB flange and LB foot mountings bolt to the face, and this -S model carries the magnet for CMSE / DMSE switches.
