This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-50 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 ACPJ20X110-50
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-50 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 ACEJ20X110-50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-50
This ACPJ20X110-50 is a double acting compact cylinder with an adjustable stroke: a stop screw trims the 110 mm extend stroke by up to 50 mm, giving a usable range of 60-110 mm. 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. The 110 mm stroke exceeds the 100 mm maximum standard stroke for the 20 mm bore, so this unit is made to order. Note: the ACPJ family is discontinued - the current-production replacement is the ACEJ20X110.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot. A rule of thumb for real work: plan on roughly 94 N (about 0.6 of the push force), which lifts around 9 kg vertically - halve that for a 2:1 margin on a vertical pick-and-place. Fixed TPU bumpers sit at both ends, and the female M6x1.0 rod thread suits standard I/Y knuckles. Confirm ISO 21287 mounting dimensions before swapping to the ACEJ20X110.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-50 (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 ACEJ20X110-50 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 ACPJ20X110-50 Is Used
Multi-product jig clamping
The 60-110 mm adjustable range lets one cylinder clamp short and long aluminium extrusions on the same fixture - turn the stop screw at changeover instead of swapping cylinders.
Battery-pack ejector station
With about 94 N of practical push at 0.5 MPa, the 20 mm bore ejects finished lithium-ion cells or small battery modules off a conveyor-mounted nest without marking the casing.
Carton flap tuck-down
The 110 mm stroke reaches across a folding-carton flap and presses it home before glue; the female M6x1.0 rod thread takes a flat knuckle pad directly.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-50 with the ACEJ20X110-50
Size both ways: if 157.1 N push at 0.5 MPa is more than your jig needs, the ACPJ16X30-20 class delivers 100.5 N at the same pressure; if you need more, step up a frame size. The 50 mm window suits fixtures where one cylinder must serve several product lengths - set the stop screw once per changeover. The adjuster is a mechanical end stop for the extend stroke only; on air loss the piston still drifts, so add a separate lock if holding is critical. This unit has no magnet (the optional -S code adds one for CMSE / DMSE switches). For new designs, order the ACEJ20X110 instead - same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-50
- ✓ 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 ACPJ20X110-50 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. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The -50 code is a 50 mm window: an external stop screw shortens the 110 mm extend stroke on site, so the effective range is 60-110 mm - it cannot lengthen past the ordered stroke. The stop is not a mid-stroke lock; the piston drifts if air is lost. The ACPJ is discontinued; the current drop-in is the ACEJ20X110 (same bore, stroke and force class) - confirm ISO 21287 mounting dimensions before swapping.
