This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ20X160-30S, 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 ACPJ20X160-30S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ20X160-30S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X160-30S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-30S
Double acting with an adjustable extend stroke, the discontinued ACPJ20X160-30S gives a 20 mm bore and a 160 mm stroke that can be trimmed by up to 30 mm with the external stop screw, so the working range is 130-160 mm. The 160 mm stroke exceeds the 100 mm standard maximum for this bore, so it is a made-to-order build. The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight gantries and guarding where a full-length body cannot fit. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and speed runs 30-500 mm/s. This model is discontinued: the current direct is the ACEJ20X160, and you should confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-30S (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 ACPJ20X160-30S Is Used
Packaging line reject gate
Mounted beside a conveyor, the rod kicks off-spec cartons or blister packs off the belt; the fitted magnet and a DMSE switch confirm the gate reached the end position on every cycle.
Lab sample indexer
The 160 mm stroke advances sample trays or vial racks one station at a time in a compact analytical instrument, where the short body fits inside guarding that an ISO 15552 profile cylinder could not.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-30S with the ACEJ20X160-30S
The stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve if the load must stay put. FA/FB flanges and LB feet bolt to the ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches. Order the ACEJ20X160 as the current-production replacement and verify mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-30S
- ✓ 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 ACPJ20X160-30S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N; the 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), and speed 30-500 mm/s.
No - the ACPJ family is discontinued, and the current-production direct is the ACEJ20X160 in the same bore, stroke and force class; confirm the ISO 21287 mounting dimensions before swapping because the ACP was DIN-standard. On this unit the -S magnet is fitted, so CMSE / DMSE switches can be mounted. The stop screw trims the 160 mm extend stroke by up to 30 mm (usable range 130-160 mm); it is a mechanical end stop, not a load-holding brake, and the fixed TPU bumpers simply decelerate the piston at each end.
