This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X70-75, 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 ACPJ16X70-75
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X70-75 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X70-75 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-75
Double acting and adjustable in stroke, the ACPJ16X70-75 is a DIN-standard compact cylinder with a 16 mm bore and a 70 mm stroke. Air drives the rod out and pulls it back, and an external stop screw trims the extend stroke anywhere inside the ordered 75 mm window, giving a usable range of 0-70 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, and the fixed TPU bumper at each end decelerates the piston at the ends of travel. Speed range is 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the short ISO 21287-class body about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. Note this model is discontinued: the current-production direct is ACEJ16X70, same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X70-75 (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 ACPJ16X70-75 Is Used
Clamping small aluminium brackets
A 16 mm bore pushing 100.5 N at 0.5 MPa holds light machined brackets in a drilling fixture, with the stop screw set to a shorter extend stroke so the clamp never over-travels into the part.
Ejecting parts from a compact mold tray
The 70 mm stroke nudges finished small components off a tray in an electronics assembly cell, and the short body fits where a full-length profile cylinder cannot.
Press-fitting nylon standoffs
About 60 N of usable force at 0.5 MPa (roughly 6 kg vertical equivalent) is enough to seat nylon standoffs into PCB spacers on a semi-automatic bench press.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-75 with the ACEJ16X70-75
The 70 mm stroke sits just under the 75 mm maximum standard stroke for bore 16, so no made-to-order stroke is needed. The stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so do not rely on it to hold a load. Rod end is a female M4x0.7 thread, port is M5x0.8, and FA/FB flange or LB foot mounts bolt to the standard face. This unit has no magnet (that is the optional -S code), so position switches are not available on this version; order ACEJ16X70-S if you need CMSE / DMSE sensing.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X70-75
- ✓ 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 ACPJ16X70-75 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. The theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The -75 code is a 75 mm adjustment window: an external stop screw shortens the 70 mm extend stroke on site to any value from 0 to 70 mm; it cannot lengthen the stroke past the ordered value. The stop is a mechanical end stop only, not a mid-stroke lock. This ACPJ model is discontinued - the current-production replacement is ACEJ16X70 (swap the P for an E), a direct in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
