This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED32X225SB, 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 ACPD Double Rod Compact Cylinder ACPD32X225SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø32mm bore and 225mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED32X225SB (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting compact cylinder with a rod leaving both covers, the ACPD32X225SB pushes and pulls with identical output: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa in each direction, because both strokes work on the rod-side area of the 32 mm bore. The 12 mm through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag, while fixed TPU bumpers at each end decelerate the piston. This 225 mm stroke is longer than the 200 mm standard for bore 32, so it is a made-to-order build.
The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, which suits long-stroke work inside tight gantries, guards and sliding doors. The S code means the magnet is fitted, so CMSE / DMSE switches can be mounted. Note this model is discontinued; the current direct is ACED32X225, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED32X225SB (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 | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).
| ACPD | DIN compact cylinder (double-rod, discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×225 | 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 through-rod drives a workpiece carrier back and forth over a 225 mm travel, with equal 345.6 N force in each direction so return speed stays consistent under load.
With the fitted -S magnet, CMSE or DMSE switches confirm open and closed positions on a machine guard slide, inside a body about 50% shorter than an ISO 15552 profile cylinder.
A rod at each cover lets the same cylinder push cartons off a conveyor from either side at about 207 N of practical force, with the rear rod carrying a sensor flag.
Size down to ACPD25 (206.2 N at 0.5 MPa) if the load is light, or up to ACPD40 (571.8 N) when you need more force at the same 1/8" port size. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. The male rod thread (B code) and PT ports are fixed on this version, and FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Since ACPD32X225SB is discontinued, order ACED32X225 as the current-production equivalent and verify the mounting dimensions against your fixture.
Replacement checklist
Because the rod exits both covers, output is equal both ways: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a maximum of 70.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 225 mm stroke is a made-to-order length above the 200 mm standard for bore 32.
The ACPD family is out of production. The current direct is ACED32X225 - swap the P for an E - which matches the same 32 mm bore, 225 mm stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before ordering, and remember the magnet on this unit is the optional -S code, not a default on every ACE.
