This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X120-100B, 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 ACPJ16X120-100B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X120-100B 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 ACEJ16X120-100B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-100B
This double acting compact cylinder from AirTAC's discontinued ACPJ line pairs a 16 mm bore with a made-to-order 120 mm stroke and a 100 mm adjustment window. A stop screw trims the extend stroke anywhere in the 20-120 mm range, and the male rod thread (B code) suits knuckle and tooling plates that bolt directly to the rod. 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. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries.
Plan on about 60 N of usable work at 0.5 MPa, which is roughly 6 kg of vertical lift with a 2:1 margin. The hard-anodized aluminium body carries M5x0.8 ports, the S45C hard-chrome rod runs on a fixed TPU bumper at each end, and speed spans 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). No magnet is fitted on this version, so position switches cannot be mounted unless you order the -S variant. This model is discontinued: the current drop-in is ACEJ16X120, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X120-100B (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 ACPJ16X120-100B Is Used
Fixture clamp with trimmed stroke
On a machining fixture, the stop screw shortens the 120 mm extend stroke so the 8 mm rod clamps a bracket at a repeatable 40 mm position instead of full travel.
Compact gantry ejector
The short body, about 50% shorter than an ISO 15552 profile cylinder, ejects small stamped parts from a die station where a full-length body would foul the frame.
Carton push-off on a packing line
At 100.5 N push (about 6 kg usable vertical lift), it nudges folded cartons off a conveyor lane within the 20-120 mm adjustable range at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-100B with the ACEJ16X120-100B
Size against the 12 mm bore (56.5 N push at 0.5 MPa) if your load is lighter, or step up to the 20 mm bore (157.1 N push) for heavier clamping. The 120 mm stroke exceeds the 75 mm standard maximum for bore 16, so it is built to order. The adjuster is a mechanical end stop for the extend stroke only - it does not lock the piston if air is lost. FA/FB flange and LB foot mounts fit the standard face. For switch-ready position feedback, order the -S code instead. Replacement: ACEJ16X120.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X120-100B
- ✓ 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 ACPJ16X120-100B FAQ
Bore 16 mm, stroke 120 mm (non-standard, made to order), rod 8 mm, M5x08 port - written M5x0.8, male rod thread. Push 100.5 N and pull 75.4 N at 0.5 MPa; push 140.7 N and pull 105.6 N at 0.7 MPa; theoretical maximum 20.5 kgf at 1.0 MPa. Operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C. The 100 mm window lets a stop screw trim the extend stroke down to 20 mm.
The ACPJ family is discontinued. The current-production replacement is ACEJ16X120 (swap the P for an E) in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. This version has no magnet, so CMSE or DMSE switches cannot be fitted; the optional -S code adds the magnet that enables them. Weight and outline dimensions: confirm from datasheet.
