This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X70-10SB, 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 ACPJ16X70-10SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X70-10SB 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 ACEJ16X70-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-10SB
This double acting ACPJ16X70-10SB is a discontinued DIN-standard compact cylinder with a 10 mm adjustable-stroke window: an external stop screw trims the 70 mm extend stroke down to 60 mm on site, so one cylinder covers several jig positions. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixtures and guarding where a full-length body will not fit.
Practical sizing: keep real work near 60 N (about 0.6 of the push figure) for a comfortable margin, which corresponds to lifting roughly 5 kg vertically - halve that to about 2.5 kg if you want a 2:1 safety factor on a vertical lift. The B code gives a male 8 mm hard-chrome S45C rod, and the S code means the optional magnet is fitted, so CMSE / DMSE switches can be mounted for end-of-stroke sensing. Note the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a load-holding lock. Since ACPJ is discontinued, plan the swap to ACEJ16X70 and confirm ISO 21287 mounting dimensions first.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X70-10SB (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 ACPJ16X70-10SB Is Used
Small-parts ejection from press dies
The 100.5 N push at 0.5 MPa is enough to kick stamped terminals or connector housings out of a die, and the 10 mm trim window lets the operator fine-tune ejection travel between 60 and 70 mm without changing cylinders.
Indexing stop on an assembly conveyor
With the -S magnet fitted, CMSE or DMSE switches confirm the extended stop position, so a 16 mm bore can gate small cartons or trays on a light conveyor at 30-500 mm/s cycle speeds.
Fixture clamp inside a compact jig
The short body, about 50% shorter in mounting length than an ISO 15552 profile cylinder, clamps PCB test fixtures or small weldment nests where a full-length body would collide with the tooling.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-10SB with the ACEJ16X70-10SB
At 16 mm bore this sits mid-range: the 12 mm bore gives 56.5 N push at 0.5 MPa for lighter clamping, while the 20 mm bore reaches 157.1 N if your load needs more force at the same pressure. The 70 mm stroke is within the 75 mm maximum standard stroke for bore 16, so no made-to-order stroke is needed. Match FA/FB flange or LB foot mounts plus I/Y rod knuckles to the ISO 21287 face. If you need position feedback, this unit already carries the -S magnet for CMSE / DMSE switches; on a new build, order the ACEJ16X70 instead, as ACPJ is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X70-10SB
- ✓ 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 ACPJ16X70-10SB FAQ
Bore 16 mm, stroke 70 mm with a 10 mm adjustment window (usable extend range 60-70 mm). Push is 100.5 N and pull 75.4 N at 0.5 MPa; at 0.7 MPa push rises to 140.7 N and pull to 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 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um, port M5x0.8, male rod thread, fixed TPU bumper at both ends.
Order the ACEJ16X70, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Before swapping, confirm the ISO 21287 mounting dimensions against your existing DIN-standard ACP fixture, and re-spec the FA/FB flange or LB foot mount and rod knuckle to the new face. This ACPJ16X70-10SB is no longer in production.
