This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE50X75B, 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 ACP50X75B
The AirTAC ACP Compact Cylinder ACP50X75B is a double acting DIN-standard tight/compact air cylinder with a Ø50mm bore and 75mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE50X75B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP50X75B
The ACP50X75B is a double acting compact cylinder in the DIN-standard ACP series, with a 50 mm bore, 75 mm stroke and a male rod thread (the B code). Air drives the piston both ways, and a fixed TPU bumper sits at each end to soften travel. At 0.5 MPa it pushes 981.7 N and pulls 881.2 N; at 0.7 MPa those figures rise to 1374.4 N and 1233.7 N, with a theoretical ceiling of 200.2 kgf at 1.0 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames and fixtures.
The body is hard-anodized aluminium with an S45C hard-chrome rod, running on 0.15-1.0 MPa (22-145 psi) filtered air at 30-500 mm/s. Note that this model is discontinued: the current-production successor is ACE50X75, a direct in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Also, without the optional -S magnet no position switch can be fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE50X75B (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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
The ACE50X75B 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 ACP50X75B Is Used
Press-fit of bushings into aluminium housings
With 981.7 N of push at 0.5 MPa, the 50 mm bore drives bushings into small gearbox and pump housings on an assembly bench, while the 75 mm stroke clears part loading.
Carton hold-down on a case-packing line
The short body mounts inside a tight packing guard, pressing lids down with about 60 kgf of usable force before the sealing head indexes to the next carton.
Fixture clamping on a CNC milling pallet
LB foot mounting bolts the cylinder to a machining fixture, clamping cast brackets during milling; the male rod thread takes a custom clamp lever directly.
Replacing the Airtac ACP Compact Cylinder ACP50X75B with the ACE50X75B
A 50 mm bore suits clamping and pressing jobs in the 550-600 N working range at 0.5 MPa. Step down to a 40 mm bore (628.3 N push) if space is tighter, or up to a 63 mm bore (1558.6 N push) when the load grows. The 75 mm stroke sits well inside the 250 mm standard limit for this bore. If the rod must hold position when air is lost, add a rod lock or pilot check valve - the bumper only decelerates, it never locks. Choose FA/FB flange, LB foot or CA/CB clevis mounting, and order the -S code if you need CMSE or DMSE switches. For new projects, specify ACE50X75 instead, since this ACP model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE50X75B
- ✓ 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 ACP50X75B FAQ
At 0.5 MPa it pushes 981.7 N and pulls 881.2 N; at 0.7 MPa, 1374.4 N push and 1233.7 N pull; theoretical maximum is 200.2 kgf at 1.0 MPa. It is double acting with a 50 mm bore, 75 mm stroke, 16 mm rod, 1/8" port (PT), male rod thread, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C and speed 30-500 mm/s.
Order ACE50X75, the ISO 21287 successor that swaps the P for an E. It matches the same bore, stroke and force class with a matching short body and mounting family. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to a DIN standard. If you need position sensing, the ACE also accepts switches where the ACP needed the optional -S magnet code.
