This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X20B, 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 ACP100X20B is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X20B (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP100X20B is a double acting compact cylinder in the discontinued AirTAC ACP DIN-standard series, with a 100 mm bore and a short 20 mm stroke on a 25 mm hard-chrome S45C rod. At 0.5 MPa it pushes 3927 N and pulls 3681.6 N, and at 0.7 MPa those figures rise to 5497.8 N and 5154.2 N, with a theoretical ceiling of 800.9 kgf at 1.0 MPa. The male rod thread (the B code) suits rod knuckles and tooling plates that bolt straight on. Its hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, which is why it fits into press fixtures and guarding where a full-length body cannot.
Air is the only fluid, filtered to 40 um, with 0.15-1.0 MPa (22-145 psi) working pressure, 1.5 MPa (215 psi) proof pressure, -20 to +70 C temperature range and 30-500 mm/s speed. Fixed TPU bumpers sit at both ends, and the 1/4" port depends only on the 100 mm bore. Note that no magnet is fitted: the optional -S code is required before CMSE or DMSE switches can be used. This model is discontinued, and the current-production direct is ACE100X20 - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X20B (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 | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | 5154 N |
| Max (@1.0 MPa) | 801 kgf | |
The ACE100X20B 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). |
|---|---|
| 100 | Bore size in mm. |
| ×20 | 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 3927 N push at 0.5 MPa gives a 20 mm-stroke clamping or staking press enough force for aluminum bracket forming on an assembly line, with the short body fitting inside the press head.
A 100 mm bore swinging or lifting a heavy conveyor gate needs the 3681.6 N pull force at 0.5 MPa, and the 1/4" port keeps flow adequate for 30-500 mm/s travel.
In a stamping shop, the short 20 mm stroke extends a heavy locating pin into a die shoe; the male rod thread accepts a machined pin adapter directly.
At this bore size the step either way is significant: the 80 mm bore delivers 2513.3 N push at 0.5 MPa, while the 100 mm bore you are viewing gives 3927 N - so if your load sits between those numbers, check whether the smaller body saves space. The 20 mm stroke is well inside the 300 mm maximum standard stroke for bore 100, so it is a catalog item, not made to order. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. Mounting brackets from the FA/FB flange, LB foot and CA/CB clevis range bolt to the same face, and the ACE100X20 is the current replacement for this discontinued model.
Replacement checklist
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa it pushes 5497.8 N and pulls 5154.2 N; theoretical maximum is 800.9 kgf at 1.0 MPa. It is a double acting compact cylinder, 100 mm bore, 20 mm stroke, 25 mm rod, 1/4" port, male rod thread, operating on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, with fixed TPU bumpers and 30-500 mm/s speed.
Order ACE100X20, 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. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before the swap. If you also need position sensing, order the ACE with the optional -S magnet so CMSE or DMSE switches can be fitted.
