This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X5SB, 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 ACPD Double Rod Compact Cylinder ACPD25X5SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X5SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X5SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X5SB
Double acting with a rod leaving both covers, the ACPD25X5SB pushes and pulls with identical force because each stroke works on the rod-side area: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction. The 5 mm stroke suits tiny positioning moves, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. A fixed TPU bumper sits at both ends, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
This is a DIN-standard compact body in hard-anodized aluminium with an S45C hard-chrome rod, and its short build saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slips into tight jigs and fixtures. The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke detection. Note this model is discontinued: the current-production direct is the ISO 21287 ACED25X5, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X5SB (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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD25X5SB Is Used
Fixture clamping in tight dies
The 5 mm stroke and short ISO 21287-class body let the 25 mm bore clamp small parts inside compact press dies where a full-length cylinder cannot fit, delivering 206.2 N both ways.
Position confirmation on assembly stations
Because the -S magnet is fitted, CMSE or DMSE switches signal the 5 mm end positions on electronics assembly fixtures, with the rear rod doubling as a flag carrier.
Push-off after small-part machining
The through-rod gives a symmetric mount on CNC finishing stations, using about 124 N of practical force to nudge finished bushings off a jig at 30-500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X5SB with the ACED25X5SB
At 25 mm bore the double-rod output is 206.2 N at 0.5 MPa in both directions. If your load is lighter, the 20 mm bore ACPD gives 117.8 N; if you need more, step up to the 32 mm bore at 345.6 N. Remember the piston drifts when air is lost, so add a rod lock or pilot check for held loads. This unit carries the optional -S magnet and a male rod thread (B code) with PT ports. Since ACPD is discontinued, order the ACED25X5 as the current ISO 21287 replacement and verify its mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACED25X5SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD25X5SB FAQ
It is a double-rod cylinder, so force is equal in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), running on air filtered to 40 um at 30-500 mm/s.
The DIN-standard short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange or LB foot mounting. The ACPD25X5SB is discontinued; the current-production direct is the ISO 21287 ACED25X5 in the same bore, stroke and force class - confirm the mounting dimensions before swapping.
