This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE50X80BH, 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 ACP50X80BH
The AirTAC ACP Compact Cylinder ACP50X80BH is a double acting DIN-standard tight/compact air cylinder with a Ø50mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE50X80BH (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP50X80BH
The ACP50X80BH is a double acting compact cylinder in the DIN-standard ACP series, with a 50 mm bore and an 80 mm stroke. At 0.5 MPa it pushes with 981.7 N and pulls with 881.2 N; at 0.7 MPa those rise to 1374.4 N and 1233.7 N, with a theoretical peak of 200.2 kgf at 1.0 MPa. The B code gives a male rod thread on the 16 mm rod, and the port thread is PT. Air supply runs 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and rod speed spans 30-500 mm/s.
Its hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight weld fixtures and packaging frames. A fixed TPU bumper sits at both ends. Note this model is discontinued: the current-production direct is the ACE50X80 (ISO 21287), so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE50X80BH (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 ACE50X80BH 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 ACP50X80BH Is Used
Carton press-down station
The 981.7 N push at 0.5 MPa seats flaps and labels on a packaging line, and the 80 mm stroke covers the full press travel in a short envelope.
Fixture clamping on a machining centre
About 589 N of working clamp force holds aluminium housings against a jig stop, with the male rod thread taking an I or Y knuckle directly.
Pallet-stacker gate latch
The short body fits inside the guard rail where a full-length cylinder will not, and the 50 kg vertical-lift equivalent covers latch and gate loads.
Replacing the Airtac ACP Compact Cylinder ACP50X80BH with the ACE50X80BH
At 50 mm bore you sit mid-range: the 40 mm bore delivers 628.3 N push at 0.5 MPa while the 63 mm bore reaches 1558.6 N, so step up if your press or clamp needs more than about 589 N of working force. This unit has no magnet, so position switches cannot be fitted; order the -S code variant if CMSE or DMSE switches are planned. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the same face. Since ACP is discontinued, specify the ACE50X80 for new builds and verify the ISO 21287 footprint.
Replacement checklist
- ✓ Current-production ACE → ACE50X80BH
- ✓ 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 ACP50X80BH FAQ
Push is 981.7 N and pull is 881.2 N at 0.5 MPa; at 0.7 MPa push is 1374.4 N and pull is 1233.7 N, with a theoretical maximum of 200.2 kgf at 1.0 MPa. Operating pressure is 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. The port is 1/8" PT and the rod is 16 mm with a male thread.
Order the ACE50X80, the ISO 21287 successor made by swapping the P for an E. It matches the same 50 mm bore, 80 mm stroke and force class with a similar short body and mounting family. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before the swap.
