This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X120B, 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 ACP100X120B
The AirTAC ACP Compact Cylinder ACP100X120B is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 120mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X120B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X120B
A double acting compact cylinder in the DIN-standard ACP series, the ACP100X120B pairs a 100 mm bore with a 120 mm stroke and a 25 mm hard-chrome S45C rod on a male thread (B code). Push force is 3927 N and pull force is 3681.6 N at 0.5 MPa, rising to 5497.8 N at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy press fixtures and gantries where a full-length body will not fit.
Note this unit is discontinued: the current-production direct is the ACE100X120, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. The hard-anodized aluminium body carries 1/4" ports, a fixed TPU bumper at both ends, and runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X120B (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 ACE100X120B 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 ACP100X120B Is Used
Die clamping on stamping presses
The 3927 N push at 0.5 MPa clamps sheet-metal dies in stamping fixtures, and the 120 mm stroke clears die changes without a long-body cylinder.
Baling and compaction stations
The 25 mm male-thread rod drives compaction rams in recycling balers, where the short body fits between conveyor frames.
Replacing the Airtac ACP Compact Cylinder ACP100X120B with the ACE100X120B
At 3927 N push and 3681.6 N pull at 0.5 MPa, this 100 mm bore covers heavy clamping and pressing; step down to the 80 mm bore (2513.3 N push) for lighter loads or accept that no larger standard bore exists in this series. Because a plain cylinder drifts when air is lost, add a rod lock or pilot check valve for held loads. Male rod thread (B) suits I/Y knuckles; FA/FB flange, LB foot and CA/CB clevis mount on the same face. No magnet is fitted on this code - order the -S version if you need CMSE / DMSE switch positions. Buy the ACE100X120 instead: it is the current replacement in this force class.
Replacement checklist
- ✓ Current-production ACE → ACE100X120B
- ✓ 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 ACP100X120B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa those rise to 5497.8 N and 5154.2 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The model is discontinued - the current-production replacement is the ACE100X120, the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before ordering.
It is a compact short-body cylinder with a hard-anodized aluminium barrel, threaded aluminium covers, a 25 mm hard-chrome rod on a male thread, 1/4" ports and a fixed TPU bumper at each end. This code has no magnet; order the -S variant to enable CMSE or DMSE reed or solid-state switches for end-of-stroke detection.
