This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE40X75SB, 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 ACP Compact Cylinder ACP40X75SB is a double acting DIN-standard tight/compact air cylinder with a Ø40mm bore and 75mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE40X75SB (ISO 21287 ACE), in the same bore, stroke and force class.
Double acting and DIN-standard compact, the ACP40X75SB pushes with 628.3 N and pulls 571.8 N at 0.5 MPa (879.6 N / 800.5 N at 0.7 MPa), driven by a 40 mm bore with a 75 mm stroke and a 12 mm male-thread rod. Air is the only fluid, filtered to 40 um, at 0.15-1.0 MPa (22-145 psi), running 30-500 mm/s. The -S magnet code on this model lets you clip CMSE or DMSE switches for end-of-stroke sensing.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and jigs. Fixed TPU bumpers sit at both ends, and the hard-anodized aluminium body carries an S45C hard-chrome rod. This model is discontinued; the current direct is ACE40X75 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE40X75SB (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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 572 N |
| 0.7 MPa | 880 N | 800 N |
| Max (@1.0 MPa) | 128 kgf | |
The ACE40X75SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| ACP | DIN compact cylinder (double-acting, discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×75 | Stroke length in mm. |
| 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).
The 628.3 N push at 0.5 MPa holds aluminium housings against locators during milling, and the 75 mm stroke clears chip conveyors in tight enclosures.
With about 38 kg of usable force at 0.5 MPa, the rod folds flaps and seats cartons at 30-500 mm/s, while the -S magnet feeds CMSE switch signals to the PLC.
The 879.6 N push at 0.7 MPa seats bearings and connectors into PCB assemblies, with the short body fitting inside a benchtop gantry frame.
At 628.3 N push at 0.5 MPa, this 40 mm unit suits clamping and pressing jobs around 38 kg of real load; step down to the 32 mm bore (402.1 N) for lighter fixtures or up to 50 mm (981.7 N) for heavier dies. Because a plain cylinder drifts when air is lost, add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face, and the 1/8" port keeps plumbing simple. Order ACE40X75 as the current-production replacement.
Replacement checklist
At 0.5 MPa the 40 mm bore delivers 628.3 N push and 571.8 N pull; at 0.7 MPa it reaches 879.6 N push and 800.5 N pull. The theoretical maximum is 128.1 kgf at 1.0 MPa. Stroke is 75 mm with a 12 mm male-thread rod and a 1/8" port, and the model is discontinued - ACE40X75 is the current replacement.
The compact body cuts roughly half the mounting length of an ISO 15552 profile cylinder, so it fits shallow machine frames. Because this model carries the -S magnet, CMSE or DMSE reed and solid-state switches mount directly for position feedback. Confirm ISO 21287 mounting dimensions when moving to ACE40X75.
