This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X120-100, 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 ACPJ16X120-100
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X120-100 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X120-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-100
The -100 code gives a 100 mm adjustment window: a stop screw trims the 120 mm extend stroke down to as little as 20 mm on site, so one cylinder covers a 20-120 mm working range. Note that the 120 mm stroke exceeds the 75 mm standard limit for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight jigs and guarding. This model is discontinued; the current direct is the ACEJ16X120 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X120-100 (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).

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-100 Is Used
Carton flap tuck station
A 20-120 mm trimmed extend stroke tucks flaps on cosmetic or pharma cartons at up to 500 mm/s, and the short body fits inside compact guarding.
Pick-and-place gantry pusher
With the optional -S magnet and CMSE / DMSE switches, the trimmed stroke ejects PCB trays from a magazine and confirms end position at each cycle.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-100 with the ACEJ16X120-100
If your load needs to be held mid-stroke, remember the stop screw is a mechanical end stop only; the rod still drifts on air loss. FA/FB flange and LB foot mounts bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches - this code has no magnet. Order the ACEJ16X120 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X120-100
- ✓ 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 ACPJ16X120-100 FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa push is 140.7 N and pull 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -100 code means a stop screw can shorten the 120 mm extend stroke by up to 100 mm, giving a usable 20-120 mm range. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 120 mm stroke is a made-to-order build since the bore 16 standard limit is 75 mm.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends and an M4x0.7 female rod thread. The ACPJ family is discontinued; the ACEJ16X120 is the current-production direct in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
