This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X30-20, 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 ACPJ16X30-20
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X30-20 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 ACEJ16X30-20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X30-20
This is a double acting, adjustable-stroke compact cylinder in the discontinued AirTAC ACPJ series. The -20 code sets a 20 mm adjustment window: an external stop screw trims the 30 mm extend stroke down to a 10 mm minimum, so one cylinder covers a 10-30 mm working range. Note that this stop is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding brake.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding where a full-length body will not fit. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and speed runs 30-500 mm/s. This model is discontinued; the current-production direct is the ACEJ16X30, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X30-20 (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 ACPJ16X30-20 Is Used
Part-present gate in electronics assembly
A 16 mm bore slides PCB trays into a test nest; with the optional -S magnet, CMSE / DMSE switches confirm the end position.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X30-20 with the ACEJ16X30-20
Step down to the 12 mm bore (56.5 N) for tighter loads, or up to the 20 mm bore (157.1 N) when force matters. This unit has no magnet fitted, so no CMSE / DMSE switch can be mounted; order the -S code if position sensing is needed. FA/FB flange and LB foot mountings bolt to the standard ISO 21287 face. Since ACPJ is discontinued, specify the ACEJ16X30 as the current replacement and verify mounting dimensions against the ISO 21287 datasheet.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X30-20
- ✓ 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 ACPJ16X30-20 FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um. The port is M5x0.8, the rod is 8 mm with a female M4x0.7 thread, and the extend stroke is adjustable from 10 to 30 mm via the 20 mm window.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends and FA/FB flange or LB foot mounting on the standard face. The ACPJ series is discontinued; the current-production replacement is the ACEJ16X30 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before ordering the swap.
