This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X275B, 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 ACP63X275B
The AirTAC ACP Compact Cylinder ACP63X275B is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 275mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X275B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X275B
The ACP63X275B is a double acting DIN-standard compact cylinder with a 63 mm bore and a 275 mm male-thread rod stroke. Air drives the piston both ways, and fixed TPU bumpers at each end take the end-of-travel shock. Push force reaches 1558.6 N and pull 1458.1 N at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding where a full-length body cannot. Note that the 275 mm stroke exceeds the 250 mm standard limit for this bore, so it is a made-to-order build.
The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod, ports are 1/8", and the B code gives a male rod thread on a PT supply port. This model is discontinued; the current-production direct is ACE63X275, so confirm the ISO 21287 mounting dimensions before swapping. If you need position feedback, order the -S variant to enable the optional magnet for CMSE / DMSE switches - this unit has no magnet fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X275B (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 ACE63X275B 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 ACP63X275B Is Used
Pallet-stacker mast assist
The 1558.6 N push at 0.5 MPa and 275 mm stroke suit a lift-assist link on a warehouse pallet stacker, where the short body keeps the mast column narrow.
Aluminium extrusion press-out
In an extrusion plant the 63 mm bore delivers about 935 N of usable work at 0.5 MPa to eject short billet offcuts from a trimming die.
Bottle-crate lowerator
A beverage-line lowerator can drop filled crates about 79 kg equivalent vertically per cylinder, using the male rod thread to pick up an I knuckle.
Replacing the Airtac ACP Compact Cylinder ACP63X275B with the ACE63X275B
At 63 mm bore this sits between the 50 mm (981.7 N push at 0.5 MPa) and the 80 mm (2513.3 N push at 0.5 MPa); step down for lighter clamping or up when 1558.6 N is marginal. Remember a plain ACP drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flanges, LB feet and CA/CB clevis bolt straight to the ISO 21287 face. Because the 275 mm stroke is non-standard for this bore, expect a made-to-order lead time, and treat ACE63X275 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE63X275B
- ✓ 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 ACP63X275B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push is 2182.1 N and pull 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The model is discontinued - the current-production direct is ACE63X275, same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to the DIN standard.
The 275 mm stroke exceeds the 250 mm standard maximum for a 63 mm bore, so this cylinder is made to order. The B code gives a male rod thread, and the 1/8" PT ports feed air at 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s. Fixed TPU bumpers at both ends absorb end-of-travel shock but never hold a load.
