This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X150-10, 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.

The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X150-10 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X150-10 (ISO 21287 ACE), in the same bore, stroke and force class.
The ACPJ16X150-10 is a discontinued double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 150 mm stroke by up to 10 mm on site, giving a usable range of 140-150 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa. The 150 mm stroke is longer than the 75 mm standard for bore 16, so it is a made-to-order build. AirTAC now supplies the ISO 21287 ACEJ16X150 as the current direct.
The hard-anodized aluminium body and S45C hard-chrome rod keep the short body about 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. A fixed TPU bumper sits at both ends, the M4x0.7 female rod thread takes standard knuckles, and this version has no magnet - the optional -S code adds one for CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X150-10 (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.
| 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).
| ACPJ | DIN compact cylinder (adjustable-stroke, discontinued). |
|---|---|
| 16 | Bore size in mm. |
| ×150 | Stroke length in mm. |
| -10 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
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).
With the optional -S magnet and CMSE / DMSE switches, the trimmed 140-150 mm extend stroke can signal end-of-stroke on PCB pin-press stations; this unit has no magnet fitted.
The 10 mm adjustment window only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA/FB flanges and LB feet bolt to the ISO 21287 face. For new projects, order the ACEJ16X150 and confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
Replacement checklist
Operating pressure is 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, port M5x0.8, rod 8 mm with an M4x0.7 female thread. The 150 mm stroke exceeds the 75 mm standard for bore 16, so it is made to order.
An external stop screw shortens the extend stroke by up to 10 mm, so the rod travels 140-150 mm; it cannot lengthen the stroke past the ordered 150 mm. The adjuster is a mechanical end stop only - it never holds a load if air is lost. The ACPJ16X150-10 is discontinued; the current-production replacement is the ACEJ16X150 (ISO 21287), so confirm mounting dimensions before swapping.
