This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X160-20SB, 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 ACPJ12X160-20SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X160-20SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm 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 ACEJ12X160-20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-20SB
This AirTAC ACPJ12X160-20SB is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 160 mm stroke by up to 20 mm, giving a usable range of 140-160 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N push at 0.7 MPa. Note that the 160 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so this unit is a made-to-order build. The model is discontinued; the current-production replacement is the ACEJ12X160 in the same bore, stroke and force class.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into narrow fixtures and guarding where a full-length body cannot. A fixed TPU bumper sits at each end, and the hard-anodized aluminium body carries an S45C hard-chrome rod with a male thread (the B code). Because the S code is on this unit, the magnet is fitted and CMSE / DMSE reed or solid-state switches can be mounted directly on the body. As a sizing rule, plan on about 34 N of real work at 0.5 MPa (roughly 0.6 of the rated push), which is about 3 kg lifted vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X160-20SB (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 (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 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 ACPJ12X160-20SB Is Used
Lab sample ejector
The 56.5 N push at 0.5 MPa is enough to eject slide trays and sample holders from compact analytical stations, with the 140-160 mm adjustable range matching varying tray depths.
Small-batch carton kickers
On a packaging line, the trimmed extend stroke diverts lightweight cartons off a conveyor without overtravel, and the fitted magnet feeds a CMSE switch for divert confirmation.
Fixture clamp on a test rig
The male rod thread plus a Y knuckle clamps thin housings in an electronics test fixture, where the short body fits inside the fixture plate footprint.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-20SB with the ACEJ12X160-20SB
At 12 mm bore this is the smallest ACPJ size: 56.5 N push at 0.5 MPa versus 100.5 N for the 16 mm bore and 157.1 N for the 20 mm bore, so step up one bore if your load sits near 34 N or above. The stop screw shortens the extend stroke only within the 20 mm window and does not lock the rod mid-stroke - on air loss the piston still drifts, so use a separate brake where holding matters. FA/FB flange or LB foot mounts bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. Since the ACPJ is discontinued, order the ACEJ12X160 as the drop-in successor and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X160-20SB
- ✓ 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 ACPJ12X160-20SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is double acting with a 20 mm adjustment window on the 160 mm extend stroke (usable 140-160 mm), M5x0.8 ports, PT thread, male rod thread, speed 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and a fixed TPU bumper at both ends. The 160 mm stroke is a made-to-order length since bore 12 tops out at 50 mm as a standard stroke.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guards. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount on the body for end-of-stroke detection. The model itself is discontinued; the current drop-in is the ACEJ12X160, and you should confirm the ISO 21287 mounting dimensions before converting.
