This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X50SBFA, 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 ACP100X50SBFA
The AirTAC ACP Compact Cylinder ACP100X50SBFA is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 50mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X50SBFA (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X50SBFA
A double acting compact cylinder in the DIN-standard ACP series, the ACP100X50SBFA pairs a 100 mm bore with a 50 mm stroke and a 25 mm hard-chrome S45C rod on a hard-anodized aluminium body. At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa push rises to 5497.8 N, with a theoretical ceiling of 800.9 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 presses, clamping fixtures and gantries where a full-length body will not fit. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and fixed TPU bumpers sit at both ends.
Because the S code is in this model number, the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. The B code gives a male rod thread and the FA suffix adds a flange mount. Note that this ACP model is discontinued: the current-production direct is ACE100X50, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X50SBFA (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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | 5154 N |
| Max (@1.0 MPa) | 801 kgf | |
The ACE100X50SBFA 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 ACP100X50SBFA Is Used
Heavy clamping fixtures
The 3927 N push at 0.5 MPa clamps steel weldments in machining and welding fixtures, with the 50 mm stroke ideal for short clamp-and-release moves.
Press and forming stations
With up to 5497.8 N at 0.7 MPa, the 100 mm bore drives light pressing, staking and swaging heads where a compact body must fit inside the machine frame.
Replacing the Airtac ACP Compact Cylinder ACP100X50SBFA with the ACE100X50SBFA
At 100 mm bore this is the top of the ACP range: 3927 N push at 0.5 MPa versus 2513.3 N for the 80 mm bore, so step down to 80 only if your load is under about 1500 N of real work. There is no larger ACP bore, so for more force move to a larger ACE or a different series. Remember a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. The FA flange suits face-mounted fixtures, and the fitted -S magnet works with CMSE / DMSE switches. Order ACE100X50 as the current replacement and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE100X50SBFA
- ✓ 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 ACP100X50SBFA FAQ
Push is 3927 N and pull 3681.6 N at 0.5 MPa; at 0.7 MPa push reaches 5497.8 N and pull 5154.2 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. It is a double acting compact cylinder, 100 mm bore, 50 mm stroke, 25 mm rod, 1/4" port, male rod thread, FA flange, operating on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s. The model is discontinued; ACE100X50 is the current replacement.
The compact aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight machine frames. Because this model carries the optional -S magnet, CMSE or DMSE reed or solid-state switches can be mounted directly for position feedback. Fixed TPU bumpers decelerate the piston at each end of travel.
