This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ20X110-100S, the same code under the new prefix. 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 ACPJ20X110-100S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ20X110-100S is a double acting, double rod, 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 ACEJ20X110-100S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100S
Double acting and adjustable in stroke, the ACPJ20X110-100S is a discontinued DIN-standard compact cylinder: 20 mm bore, 110 mm stroke, 10 mm rod, M5x0.8 ports. Push force is 157.1 N and pull 117.8 N at 0.5 MPa, rising to 219.9 N on extension at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. Its hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C.
The -100 code is a 100 mm adjustment window: a stop screw trims the extend stroke anywhere from 10 to 110 mm on site, so one cylinder serves several jig depths. The 110 mm stroke is above the 100 mm standard maximum for bore 20, so it is made to order. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder. This model carries the optional -S magnet, so CMSE / DMSE switches can be fitted. It is discontinued; the current direct is ACEJ20X110, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-100S (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 kgf |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100S Is Used
Fixture depth trimming
On a CNC jig for aluminium brackets, the 100 mm window lets one 20 mm cylinder serve part variants from 10 to 110 mm of clamp travel without swapping hardware.
End-position detection on small assemblies
With the fitted -S magnet, CMSE or DMSE switches confirm full extension on a 110 mm ejection move in an electronics assembly head, at speeds from 30 to 500 mm/s.
Light press and insert work
About 94 N of usable push at 0.5 MPa suits pressing dowel pins or snap fits into plastic housings where a heavier 32 mm bore would mar the part.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-100S with the ACEJ20X110-100S
The 110 mm stroke is non-standard for bore 20 (max standard 100 mm), so it is a made-to-order build. The -100 window lets you trim the extend stroke down to 10 mm without changing hardware, but the stop screw is a mechanical end stop only: on air loss the piston still drifts, so do not rely on it to hold a load. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. For new projects, order the current ACEJ20X110 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-100S
- ✓ 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 ACPJ20X110-100S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N; the theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed is 30-500 mm/s.
The -100 code is a 100 mm adjustment window: an external stop screw shortens the 110 mm extend stroke down to 10 mm on site. It is an end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Fixed TPU bumpers decelerate at both ends. The ACPJ family is discontinued; the current-production direct is ACEJ20X110 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACPJ follows the DIN-standard footprint.
