This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X25SB, 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 ACP Compact Cylinder ACP63X25SB
The AirTAC ACP Compact Cylinder ACP63X25SB is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 25mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X25SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X25SB
The ACP63X25SB is a double acting compact cylinder in the DIN-standard ACP family, with a 63 mm bore and a short 25 mm stroke. It delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N push at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. The hard-anodized aluminium body carries 1/8" ports, and the 16 mm S45C hard-chrome rod ends in a male thread (the B code). The S in the code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted directly on the body.
Because the body follows the short ISO 21287 format, it saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which makes it a strong fit for tight clamping fixtures and slide assemblies. Note this model is discontinued: the current-production direct is ACE63X25, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X25SB (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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
The ACE63X25SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP63X25SB Is Used
Weldment clamp fixtures
The 1558.6 N push at 0.5 MPa clamps steel brackets in welding jigs, and the short 25 mm stroke keeps the fixture footprint narrow inside the gantry.
Case ejector on a packaging line
A quick 25 mm kick pushes misaligned cartons off a conveyor lane, with the fitted -S magnet feeding position feedback to CMSE or DMSE switches on the PLC.
Small press-fit station
About 159 kg of thrust at 0.5 MPa presses bushings into aluminium housings where a full-length cylinder would never fit under the press head.
Replacing the Airtac ACP Compact Cylinder ACP63X25SB with the ACE63X25SB
Size the job both ways before committing. If your load needs under 981.7 N push at 0.5 MPa, a bore 50 unit is cheaper and lighter; if you need more than 1558.6 N, step up to the 80 mm bore with 2513.3 N. Keep speed between 30 and 500 mm/s and remember that a plain unit of this type will not hold a vertical load when air is lost - add a rod lock or pilot check valve for held positions. FA/FB flange, LB foot, CA/CB clevis, CR, SDB and FTC mounts plus I/Y rod knuckles bolt to the standard face. Since the ACP63X25SB is discontinued, order ACE63X25 as the current equivalent and verify the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACE63X25SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP63X25SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa that rises to 2182.1 N push and 2041.3 N pull, with a theoretical maximum of 317.9 kgf at 1.0 MPa. It is a double acting unit with a 63 mm bore, 25 mm stroke, 16 mm male-thread rod, 1/8" ports, operating pressure 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, and a fixed TPU bumper at both ends. The model is discontinued and replaced by ACE63X25.
The ISO 21287-style compact body cuts about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped jigs, slides and guards. The S in ACP63X25SB means the optional -S magnet is fitted on this unit, letting you snap CMSE or DMSE reed or solid-state switches onto the body for end-of-stroke sensing. FA/FB flange, LB foot, CA/CB clevis, CR, SDB and FTC mounts attach directly. For new builds, order ACE63X25 and confirm the ISO 21287 mounting dimensions.
