This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X45SB, 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 ACP100X45SB
The AirTAC ACP Compact Cylinder ACP100X45SB is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 45mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X45SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X45SB
A double acting compact cylinder in the DIN-standard ACP series, the ACP100X45SB pairs a 100 mm bore with a short 45 mm stroke and a male-threaded 25 mm rod. Its hard-anodized aluminium body and S45C hard-chrome rod deliver 3927 N push and 3681.6 N pull at 0.5 MPa, rising to 5497.8 N at 0.7 MPa. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and gantries where a full-length body will not fit.
This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke detection. Note that the fixed TPU bumpers only soften the ends of travel - if your press must hold a die under load when air is lost, add a rod lock or pilot check valve. This model is discontinued; the current-production direct is ACE100X45, so confirm the ISO 21287 mounting dimensions before swapping. As a sizing rule, plan on roughly 2356 N (about 240 kgf) of usable force at 0.5 MPa rather than the full rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X45SB (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 ACE100X45SB 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 ACP100X45SB Is Used
Bench-top crimping press
With 3927 N push at 0.5 MPa the 100 mm bore crimps terminals and small bushings on an electronics assembly bench, and the 45 mm stroke keeps the tooling cycle fast.
Fixture clamping on a machining center
The short body bolts into tight jig plates where an ISO 15552 profile cylinder would overhang, holding cast housings against a milling fixture with about 240 kgf of usable force.
Case ejector on a packing line
Mounted with an FA flange, the cylinder kicks formed cartons off a forming station at up to 500 mm/s, and CMSE switches on the -S magnet confirm each ejection.
Replacing the Airtac ACP Compact Cylinder ACP100X45SB with the ACE100X45SB
At 100 mm bore this is the top of the ACP range: 3927 N push at 0.5 MPa where an 80 mm bore gives 2513.3 N and there is no larger standard option. The 45 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so it is a catalog item, not a made-to-order length. The B code gives a male rod thread on the 25 mm rod, and the 1/4" port feeds the air. If you need position feedback, this S-coded version already includes the magnet for CMSE / DMSE switches; order the plain ACP100X45B if you do not. Since ACP is discontinued, specify ACE100X45 as the current replacement and verify the ISO 21287 footprint against your fixture first.
Replacement checklist
- ✓ Current-production ACE → ACE100X45SB
- ✓ 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 ACP100X45SB FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa that rises to 5497.8 N push and 5154.2 N pull, with a theoretical maximum of 800.9 kgf at 1.0 MPa. In practice, budget about 2356 N of push for real work at 0.5 MPa.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis brackets available. The ACP family is no longer in production: the current direct is ACE100X45, the ISO 21287 successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions against your existing fixture before ordering the swap.
