This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-100B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-100B 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 ACPJ20X110-100B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100B 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 ACEJ20X110-100B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100B
This double acting ACPJ20X110-100B is a DIN-standard compact cylinder with a 20 mm bore and a 110 mm stroke that an external stop screw trims by up to 100 mm, giving a usable extend range of 10-110 mm. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical 32 kgf at 1.0 MPa. The 110 mm stroke exceeds the 100 mm standard maximum for this bore, so it is a made-to-order item. Note the ACPJ family is discontinued - the current-production drop-in is ACEJ20X110.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped jigs and gantries. A fixed TPU bumper sits at both ends and only decelerates the piston - it never locks or holds a load, and on air loss the rod still drifts. The B code gives a male M6x1.0 rod thread; ports are M5x0.8. No magnet is fitted on this version, so position switches cannot be used - order the -S code for that. For sizing, treat about 94 N (roughly 0.6 of the push force) as the practical working effort, which lifts about 8 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-100B (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 ACEJ20X110-100B 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 ACPJ20X110-100B Is Used
Multi-stop ejection on assembly fixtures
The 10-110 mm trim range lets one cylinder eject parts at different depths per product variant, with 157.1 N of push at 0.5 MPa clearing small housings from nests.
Carton flap tucking on a packaging line
About 94 N of practical working force folds flaps on 200 mm cartons at speeds up to 500 mm/s, and the short body fits inside tight guarding.
Sample press in a lab automation cell
The male M6x1.0 rod thread accepts a knuckle for a light pressing head, delivering up to 219.9 N at 0.7 MPa for sealing microplates or crimping vials.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100B with the ACEJ20X110-100B
Compare both directions: the 16 mm bore delivers 100.5 N push at 0.5 MPa, while the 25 mm class steps up well beyond this 20 mm bore's 157.1 N - pick the smaller bore if 100 N covers the job. The 100 mm adjustment window suits stations where one cylinder must serve several stop positions. Match FA/FB flange or LB foot hardware to the ISO 21287 face, and remember the male M6x1.0 rod thread when ordering knuckles. Since this model is discontinued, spec ACEJ20X110 as the replacement and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-100B
- ✓ 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 ACPJ20X110-100B 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 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um. The stop screw trims the 110 mm stroke by up to 100 mm (usable 10-110 mm). The 110 mm stroke is a made-to-order length above the 100 mm standard maximum for bore 20.
It is a short-body compact cylinder with a hard-anodized aluminium body, S45C hard-chrome rod and a fixed TPU bumper at each end that only decelerates the piston at the ends. It saves about 50% of the mounting length of an ISO 15552 profile cylinder and takes FA/FB flange or LB foot hardware. This version has no magnet, so no switch can be mounted - order the -S code to enable CMSE / DMSE switches. The model is discontinued; ACEJ20X110 is the current drop-in, so verify ISO 21287 mounting dimensions before converting.
