This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X30-20B, 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 ACPJ16X30-20B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X30-20B is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X30-20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X30-20B
The ACPJ16X30-20B is a discontinued double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 30 mm stroke by up to 20 mm, giving a usable range of 10-30 mm. The B code gives a male rod thread on the 8 mm rod, and the M5x0.8 port follows the 16 mm bore. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa that rises to 140.7 N push and 105.6 N pull, with a theoretical ceiling of 20.5 kgf at 1.0 MPa.
The hard-anodized aluminium body with an S45C hard-chrome rod is an ISO 21287 short build that saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. In practice, plan on about 60 N of real work at 0.5 MPa, which lifts roughly 5 kg vertically with a 2:1 margin. This model is discontinued; the current-production drop-in is the ACEJ16X30, so confirm the ISO 21287 mounting dimensions before swapping from the DIN-standard ACP footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X30-20B (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 (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 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 ACPJ16X30-20B Is Used
Fixture clamping on a small CNC jig
The 10-30 mm adjustable range lets a machinist trim the clamp stroke to the part without re-plumbing, and 100.5 N at 0.5 MPa holds light aluminium workpieces.
Ejection pusher on a compact assembly head
A 30 mm stroke ejects finished clips or pins from a nest; the male rod thread takes an I-type knuckle straight off the shelf.
Bench-top press for connector crimping
About 60 N of usable force at 0.5 MPa suits low-force crimp and stake operations where a full-length cylinder will not fit the frame.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X30-20B with the ACEJ16X30-20B
Size against neighbours: the 12 mm bore delivers 56.5 N push at 0.5 MPa, while stepping up to 20 mm gives 157.1 N - pick 16 mm when your load sits between those. The 20 mm adjustment window shortens the extend stroke only; it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. This unit has no magnet (the optional -S code adds one for CMSE / DMSE switches), a male rod thread for direct knuckle mounting, and FA/LB brackets that bolt to the ISO 21287 face. Order the ACEJ16X30 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X30-20B
- ✓ 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 ACPJ16X30-20B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa, 140.7 N push and 105.6 N pull; theoretical maximum 20.5 kgf at 1.0 MPa. It is double acting with a 30 mm stroke trimmed by a 20 mm adjustment window (usable 10-30 mm), an 8 mm male-thread rod, M5x0.8 port, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-500 mm/s speed and a fixed TPU bumper at both ends.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange or LB foot mounts plus I/Y knuckles bolt to the standard face. This ACPJ is discontinued; the ACEJ16X30 is the current drop-in in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP was DIN-standard.
