This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X125SB, 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 ACP63X125SB
The AirTAC ACP Compact Cylinder ACP63X125SB is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 125mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X125SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X125SB
The ACP63X125SB is a double acting DIN-standard compact cylinder with a 63 mm bore and 125 mm stroke, driven by air in both directions and fitted with a fixed TPU bumper at each end. At 0.5 MPa it pushes with 1558.6 N and pulls with 1458.1 N, rising to 2182.1 N push at 0.7 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight welding jigs and packaging gantries where a full-length body simply will not fit.
This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped onto the body for end-of-stroke sensing, and the B code gives a male rod thread on the 16 mm rod. As a working rule, keep real work to about 935 N (roughly 95 kg of vertical lift) at 0.5 MPa rather than the full rating. Note that ACP is discontinued: the current-production direct is ACE63X125, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X125SB (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 ACE63X125SB 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 ACP63X125SB Is Used
Welding fixture clamping
The 1558.6 N push at 0.5 MPa seats steel brackets into a weld jig, and the short body fits between fixture rails where a full-length profile cylinder cannot.
Case press on a carton line
A 125 mm stroke closes carton flaps on a packaging machine, with CMSE switches on the -S magnet confirming each cycle at up to 500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP63X125SB with the ACE63X125SB
For a 125 mm stroke in the 1500 N class, the 63 mm bore is the right pick: the 50 mm bore manages only 981.7 N push at 0.5 MPa, while stepping up to 80 mm buys 2513.3 N if your fixture can take the larger envelope. Remember that a plain cylinder of this type drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis brackets bolt to the same face, and the male-threaded rod suits I/Y knuckles. Order ACE63X125 as the current replacement and verify the ISO 21287 hole pattern first.
Replacement checklist
- ✓ Current-production ACE → ACE63X125SB
- ✓ 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 ACP63X125SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those rise to 2182.1 N push and 2041.3 N pull. The theoretical maximum at 1.0 MPa is 317.9 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 1/8" port depends on the 63 mm bore.
The hard-anodized aluminium body is a short DIN-standard compact build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options. The ACP family is discontinued; ACE63X125 is the current ISO 21287 direct in the same bore, stroke and force class, so confirm the mounting dimensions before ordering.
