This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X70-30B, 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 ACPJ16X70-30B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X70-30B 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 ACEJ16X70-30B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-30B
This discontinued AirTAC unit is a double acting compact cylinder with an adjustable extend stroke. The 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N at 0.7 MPa, with a theoretical ceiling of 20.5 kgf at 1.0 MPa. An external stop screw trims the 70 mm stroke by up to 30 mm, giving a usable extend range of 40-70 mm. The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. Note that the stop is a mechanical end stop only: on air loss the piston still drifts, so it must never be treated as a load-holding brake.
For sizing, plan on about 60 N of real work at 0.5 MPa (roughly 60% of the rated push), which corresponds to lifting about 5 kg vertically, or roughly 2.5 kg with a 2:1 margin. The rod end carries a male thread (the B code) and the air supply connects through M5x0.8 ports. The optional -S magnet enables CMSE / DMSE switches; without it no sensing is possible. This model is discontinued: the current-production drop-in is the ACEJ16X70 in the ISO 21287 family, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X70-30B (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 ACPJ16X70-30B Is Used
Small-parts ejection on assembly benches
Trims the extend stroke between 40 and 70 mm to eject finished connectors or terminals from a nest, with the 100.5 N push at 0.5 MPa enough for parts under about 60 N of resistance.
Indexing stop on a light conveyor line
Acts as an adjustable end-of-line stop for cartons up to roughly 2.5 kg lifted vertically with a 2:1 margin, using the male-threaded rod to attach a custom stop pad.
Sample press in a lab automation cell
Applies controlled clamping to vials or microplates at 140.7 N push at 0.7 MPa, with the short ISO 21287-class body fitting inside compact enclosure frames.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-30B with the ACEJ16X70-30B
Compare both directions before committing: the 12 mm bore pushes 56.5 N at 0.5 MPa while the 20 mm bore reaches 157.1 N, so the 16 mm sits in the middle at 100.5 N push and 75.4 N pull. If your fixture needs a fixed stroke instead of a trimmed one, the ACP16X70 (replaced by ACE16X70) is the related type; for a rod through both ends, the ACPD double-rod version applies. FA/FB flange and LB foot mounts bolt to the standard face, and I/Y rod knuckles fit the male thread. Order the -S code if you need CMSE / DMSE switch positions. The ACEJ16X70 is the current replacement - verify ISO 21287 dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X70-30B
- ✓ 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 ACPJ16X70-30B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The 16 mm bore has an 8 mm rod, M5x0.8 ports, a 30 mm adjustment window on the 70 mm stroke (usable range 40-70 mm), operating pressure 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, and a fixed TPU bumper at both ends.
Position sensing requires the optional -S magnet at order time; without that code there is no magnet and no CMSE / DMSE switch can be fitted. This ACPJ is discontinued, so for new builds specify the ACEJ16X70, the current-production ISO 21287 successor in the same bore, stroke and force class - confirm the mounting dimensions against the DIN-standard ACP footprint before swapping.
