This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X100-75S, 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 ACPJ12X100-75S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X100-75S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X100-75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-75S
Double acting and adjustable in stroke, the ACPJ12X100-75S is a discontinued DIN-standard compact cylinder with a 12 mm bore and a 100 mm stroke that a stop screw can trim by up to 75 mm, giving a usable extend range of 25-100 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N / 59.4 N at 0.7 MPa. Because the short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight fixtures and guarding where a full-length body cannot. The 100 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a made-to-order item.
A practical sizing check: treat roughly 0.6 of the 56.5 N push as usable work at 0.5 MPa, about 34 N, which is roughly 3 kg of vertical lift with a margin - enough for small clamps, gates and sensors trays. The hard-anodized aluminium body carries a fixed TPU bumper at both ends, the S45C rod ends in a female M3x0.5 thread, and the fitted -S magnet accepts CMSE / DMSE switches. This model is discontinued; the current-production drop-in is the ACEJ12X100, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-75S (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 ACPJ12X100-75S Is Used
Small-part ejection on assembly benches
The 25-100 mm adjustable extend range lets one cylinder serve several fixture variants, nudging finished 3-5 g parts off a jig at about 3 kg of usable vertical force at 0.5 MPa.
Position-confirmed slide gates in test rigs
With the fitted -S magnet and CMSE / DMSE switches, both end positions of the trimmed stroke are confirmed electrically, ideal for interlocked covers on electronics test stations.
Light hold-down of PCBs in solder pallets
About 34 N of practical push at 0.5 MPa holds thin circuit boards flat during wave-solder transfer, and the short body fits inside the pallet frame where longer bodies cannot.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-75S with the ACEJ12X100-75S
At 56.5 N push at 0.5 MPa this 12 mm bore suits light clamping and positioning; step up to the 16 mm bore (100.5 N) or the 20 mm bore (157.1 N) if the load grows. Remember the stop screw trims the extend stroke only - it is not a mid-stroke lock, so the rod still drifts if air is lost. The 75 mm window covers jobs needing anywhere from 25 mm to the full 100 mm. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet lets you add CMSE / DMSE switches for end-position sensing. Order the ACEJ12X100 instead: this ACPJ is discontinued, and the ACE matches the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-75S
- ✓ 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 ACPJ12X100-75S FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -75 code gives a 75 mm adjustment window, so the stop screw trims the 100 mm extend stroke anywhere down to 25 mm. The 100 mm stroke is a made-to-order length because the standard maximum for a 12 mm bore is 50 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
It is a compact short-body cylinder with a hard-anodized aluminium body, an S45C hard-chrome rod with a female M3x0.5 thread, an M5x0.8 port and a fixed TPU bumper at each end - the body is roughly 50% shorter in mounting length than an ISO 15552 profile cylinder. The -S magnet fitted to this model accepts CMSE / DMSE switches. The ACPJ family is discontinued; the current-production drop-in is the ACEJ12X100 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap.
