This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE50X80S, 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 ACP50X80S
The AirTAC ACP Compact Cylinder ACP50X80S 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 ACE50X80S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP50X80S
A double acting compact cylinder built to the DIN-standard short-body format, the ACP50X80S pairs a 50 mm bore with an 80 mm stroke and carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted directly on the hard-anodized aluminium body. 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. The 16 mm S45C hard-chrome rod ends in a female M10x1.5 thread and the air ports are 1/8".
Because the short body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, this unit slots into tight clamping fixtures and guarding where a full-length cylinder cannot. Note that this model is discontinued: the current-production direct is ACE50X80, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE50X80S (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 ACE50X80S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACP Compact Cylinder ACP50X80S Is Used
Fixture clamping on CNC pallets
The 981.7 N push at 0.5 MPa secures aluminium housings in machining fixtures, and the short body fits inside the clamp pocket where a full-length cylinder would foul the pallet.
Position-verified ejector
The fitted -S magnet accepts CMSE or DMSE switches, so a PLC confirms full extension before the next indexing step on an assembly transfer line.
Replacing the Airtac ACP Compact Cylinder ACP50X80S with the ACE50X80S
For this 80 mm stroke, a 40 mm bore delivers 628.3 N push at 0.5 MPa while a 63 mm bore reaches 1558.6 N - step up if your clamping or pressing duty sits near the 981.7 N rating of this 50 mm unit. 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 mountings bolt straight on, and the -S magnet on this model enables CMSE / DMSE position switches. Order ACE50X80 as the current replacement and verify ISO 21287 hole patterns first.
Replacement checklist
- ✓ Current-production ACE → ACE50X80S
- ✓ 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 ACP50X80S 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. The theoretical maximum is 200.2 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed range 30-500 mm/s, and the 16 mm rod carries a female M10x1.5 thread with 1/8" ports.
Order ACE50X80, the ISO 21287 successor that swaps the P for an E and matches the same 50 mm bore, 80 mm stroke and force class. The short body still saves about 50% of the mounting length of an ISO 15552 profile cylinder, but because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions and FA/FB, LB or CA/CB hole patterns before the swap.
