This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X50SFA, 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.

The AirTAC ACP Compact Cylinder ACP100X50SFA 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 ACE100X50SFA (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting compact cylinder built to the DIN-standard short-body format, the ACP100X50SFA pairs a 100 mm bore with a 50 mm stroke and an FA flange already specified in the order code. At 0.5 MPa it pushes with 3927 N and pulls with 3681.6 N, rising to 5497.8 N on the extend stroke at 0.7 MPa - enough headroom for heavy clamping and pressing fixtures. The hard-anodized aluminium body with an S45C hard-chrome 25 mm rod runs on filtered air at 0.15-1.0 MPa (22-145 psi) and strokes 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 presses, weld fixtures and gantry clamps where a full-length body will not reach. Because this model carries the optional -S magnet, CMSE or DMSE reed and solid-state switches can be fitted for end-of-stroke signalling. One practical planning figure: at 0.5 MPa the usable push is roughly 2356 N, which is about 240 kg of vertical working load once a 40% margin is kept back. 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 ACE100X50SFA (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.
| 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 ACE100X50SFA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| ACP | DIN compact cylinder (double-acting, discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×50 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
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).
The 3927 N push at 0.5 MPa pre-clamps steel plate stacks in a fabrication shop before a hydraulic press closes, with the 50 mm stroke covering stack height variation.
On an automotive subassembly weld line, the FA flange mounts the cylinder over a fixture table to hold brackets down through the weld cycle, with DMSE switches confirming full clamp.
In a warehouse conveyor line, the short body swings heavy pallet stop gates where a full-length profile cylinder would foul the guard rail, lifting gate sections of about 200 kg with margin.
At this bore size the step either way is large: a 63 mm bore delivers 1558.6 N push at 0.5 MPa while the 100 mm gives 3927 N, so if your fixture needs under 1500 N the smaller bore saves air and cost. For heavier work at the same stroke, the next step up does not exist in this family - 100 mm is the largest bore. Keep in mind the piston drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. The FA flange in this code bolts to the standard ISO 21287 face, and the -S magnet is already included for CMSE / DMSE switching. Order ACE100X50 as the current replacement and verify mounting dimensions against the ISO 21287 drawing.
Replacement checklist
Push is 3927 N and pull is 3681.6 N at 0.5 MPa; at 0.7 MPa push rises to 5497.8 N. Theoretical maximum at 1.0 MPa is 800.9 kgf. This model is discontinued - the current-production direct is ACE100X50, same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the older DIN-standard layout.
The compact aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with aluminium covers threaded onto the body and a fixed TPU bumper at each end that simply decelerates the piston. This unit carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount directly on the body for end-of-stroke detection. Port is 1/4" PT and the female rod thread is M16x1.5.
