This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ20X175-100, 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 ACPJ20X175-100
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ20X175-100 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 175mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X175-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X175-100
This ACPJ20X175-100 is a double acting compact cylinder with an adjustable extend stroke: the -100 code gives a 100 mm stop-screw window, so the 175 mm stroke can be trimmed on site anywhere down to 75 mm. Note the 175 mm stroke exceeds the 100 mm standard limit for bore 20, so it is a made-to-order build.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight gantries and guarding. This model is discontinued: the current-production direct is the ACEJ20X175, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X175-100 (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 ACPJ20X175-100 Is Used
Small parts ejector on a press bench
Ejects formed terminals or bushings from a die shoe; the compact body fits where a full-length profile cylinder will not, and the 9.6 kg vertical-lift margin covers light workpieces.
Packaging line push-off station
Pushes cartons or blisters off a narrow conveyor at 30-500 mm/s; the stop screw sets the exact extend position per product size within the 75-175 mm range.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X175-100 with the ACEJ20X175-100
Size both ways before ordering: the 16 mm bore pushes 100.5 N at 0.5 MPa if your load is lighter, while the next class up gives more margin for heavier clamping. The stop screw only shortens the extend stroke within the 100 mm window - it is a mechanical end stop, not a mid-stroke lock, so the rod will still drift if air is lost. FA/FB flange and LB foot mountings bolt to the standard face. No magnet is fitted on this code; order the -S version if you need CMSE / DMSE switch positions. For new projects, specify the ACEJ20X175 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X175-100
- ✓ 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 ACPJ20X175-100 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; theoretical maximum is 32 kgf at 1.0 MPa. The -100 code is a 100 mm adjustment window: an external stop screw shortens the 175 mm extend stroke to any value down to 75 mm. It shortens the stroke only - it never lengthens it past 175 mm and does not hold a load on air loss. The 175 mm stroke is made to order, since the bore 20 standard maximum is 100 mm.
No - the ACPJ family is discontinued. The current-production replacement is the ACEJ20X175 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 short-body format. Because the ACPJ was built to a DIN-standard compact design, confirm the ISO 21287 mounting dimensions against your fixture before swapping. Also note this unit has no magnet fitted; the optional -S code is what enables CMSE / DMSE position switches.
