This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X35SB, 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 ACPD25X35SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X35SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X35SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X35SB
This is a double acting, double-rod compact cylinder: a piston rod exits both covers, so the through-rod delivers equal force in each direction and resists rotation and light side load. On this 25 mm bore, output is 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on both strokes, since both sides work on the rod-side area. The S code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted directly on the body.
The hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a fixed TPU bumper at each end. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which suits tight jigs and gantries. Note this model is discontinued: the current-production direct is ACED25X35, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X35SB (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 ACPD25X35SB Is Used
Symmetric jig clamping
The through-rod clamps from either cover with equal 206.2 N force at 0.5 MPa, ideal for a two-sided drilling fixture on a small machining cell.
Switched pick-and-place slide
With the fitted -S magnet, CMSE or DMSE switches confirm end positions on a 35 mm stroke transfer slide moving small electronics trays at 30-500 mm/s.
Conveyor push-off station
The back-end rod carries a sensor flag or guide while the front rod pushes cartons sideways off a packaging line conveyor with 288.6 N at 0.7 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X35SB with the ACED25X35SB
The male rod thread (B code) takes I/Y knuckles directly, and FA/FB flange or LB foot mounts bolt to the standard face. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Order ACED25X35 as the current replacement and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED25X35SB
- ✓ 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 ACPD25X35SB FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal both ways: 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), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, port M5x0.8, rod 10 mm with male thread, and the maximum standard stroke for this bore is 150 mm.
The ACPD family is no longer in production. The current-production direct is ACED25X35, the ISO 21287 ACE successor in the same bore, stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions, since the ACP was built to the DIN standard. The fixed TPU bumpers, optional -S magnet for CMSE / DMSE switches and FA/FB, LB, CA/CB, CR, SDB and FTC mounting family carry over in concept.
