This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE50X80SB, 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 ACP50X80SB
The AirTAC ACP Compact Cylinder ACP50X80SB 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 ACE50X80SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP50X80SB
The ACP50X80SB is a double acting DIN-standard compact cylinder with a 50 mm bore and 80 mm stroke, a male threaded rod and a 1/8" air port. 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, peaking at a theoretical 200.2 kgf at 1.0 MPa. Its hard-anodized aluminium body and S45C hard-chrome rod run on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a fixed TPU bumper at each end.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight presses and fixtures. Because the -S magnet is fitted, CMSE or DMSE switches can be clipped on for end-of-stroke signals. Note: this model is discontinued; the current direct is ACE50X80, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE50X80SB (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 ACE50X80SB 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 ACP50X80SB Is Used
Bench-top press station
With 981.7 N of push at 0.5 MPa (about 589 N of usable force), the 50 mm bore handles light staking and swaging of aluminium terminals on a compact press jig where a full-length profile cylinder will not fit.
Fixture clamping on CNC pallets
The 80 mm stroke and male rod thread suit swing clamps and link clamps on machining fixtures; the short body saves roughly half the mounting length of an ISO 15552 profile cylinder inside the pallet envelope.
Gated conveyor diverters
The fitted -S magnet lets CMSE or DMSE switches confirm push and pull positions (881.2 N return at 0.5 MPa) on packaging-line divert gates running at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP50X80SB with the ACE50X80SB
For an 80 mm stroke, the 50 mm bore delivers 981.7 N of push at 0.5 MPa - enough for clamping and pressing work around 589 N with a sensible margin. If your load needs less, the ACP40X80SB gives 628.3 N at the same pressure; if it needs more, step up to the ACP63X80SB with 1558.6 N. Keep in mind a plain unit drifts when air is lost, so add a rod lock or pilot check valve for held loads. FA/FB flange, LB foot and CA/CB clevis mounts bolt straight on, and the -S magnet in this code accepts CMSE / DMSE switches. Since ACP is discontinued, order ACE50X80 as the current-production equivalent and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE50X80SB
- ✓ 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 ACP50X80SB 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 a double acting compact cylinder, 50 mm bore, 80 mm stroke, 16 mm rod with male thread, 1/8" port, operating on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, -20 to +70 C, with a fixed TPU bumper at both ends. The model is discontinued - ACE50X80 is the current replacement.
Yes - the S in this model code means the optional -S magnet is fitted, so CMSE reed or DMSE solid-state switches can be mounted directly on the body for end-of-stroke detection. Mounting options include FA and FB flanges, LB foot, CA and CB clevis, plus CR, SDB pivot and FTC brackets. Because ACP is discontinued, check the ISO 21287 mounting dimensions of the ACE50X80 successor before designing it into a new fixture.
