This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X100-30SB, 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 ACPJ12X100-30SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X100-30SB 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 ACEJ12X100-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-30SB
This ACPJ12X100-30SB is a discontinued double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 100 mm stroke by up to 30 mm, giving a usable range of 70-100 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. Its 100 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a made-to-order build. The -S magnet is fitted, so CMSE or DMSE switches can be mounted for end-of-stroke signalling.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits slim jigs and guarded assemblies. A fixed TPU bumper sits at both ends, and the hard-anodized aluminium body carries an S45C hard-chrome rod with a male thread (B code). For sizing: the push force supports about 34 N of real work at 0.5 MPa, roughly a 2.9 kg vertical lift with a 2:1 margin. Production has ended - the current drop-in is ACEJ12X100, but confirm ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-30SB (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 ACPJ12X100-30SB Is Used
Small-part ejection on assembly fixtures
The 70-100 mm adjustable range lets a fixture builder trim the extend stroke so a 6 mm rod ejects a bushing or pin exactly to a nest, with about 34 N of usable push at 0.5 MPa.
Position-signalled test stations
With the -S magnet fitted, CMSE or DMSE switches confirm rod position on a leak-test or go/no-go gauge station, cycling at 30-500 mm/s within the 70-100 mm window.
Compact clamping inside guarded cells
A body about 50% shorter than an ISO 15552 profile cylinder fits tight gantry brackets, pressing light plastic housings with up to 79.2 N at 0.7 MPa.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-30SB with the ACEJ12X100-30SB
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 and 157.1 N for the 20 mm. If your load needs more than about 34 N of usable force, step up a bore. The 30 mm window only shortens the extend stroke - it is a mechanical stop, not a mid-stroke lock, so the rod can drift if air is lost. FA/FB flange or LB foot mounts bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. Order the ACEJ12X100 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-30SB
- ✓ 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 ACPJ12X100-30SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa that rises to 79.2 N push and 59.4 N pull, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is double acting, runs on 0.15-1.0 MPa (22-145 psi) filtered air, moves at 30-500 mm/s, and the stop screw trims the 100 mm stroke by up to 30 mm (70-100 mm usable). Note the 100 mm stroke is made to order - the standard maximum for a 12 mm bore is 50 mm.
AirTAC no longer produces the ACPJ family. The current drop-in is the ACEJ12X100 (swap the P for an E), an ISO 21287 adjustable-stroke cylinder in the same 12 mm bore, 100 mm stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions, because the ACP was built to a DIN-standard footprint. The male rod thread, M5x0.8 port and optional -S magnet concept carry over, but verify the fixture interface.
