This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE40X150SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE40X150SB in place of this model. 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 Airtac ACP Compact Cylinder ACP40X150SB is a double acting DIN-standard tight/compact air cylinder with a Ø40mm bore and 150mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE40X150SB (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP40X150SB is a double acting DIN-standard compact cylinder with a 40 mm bore and 150 mm stroke, driving a 12 mm hard-chrome S45C rod through a male thread (the B code). At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa those figures rise to 879.6 N and 800.5 N, with a theoretical peak of 128.1 kgf at 1.0 MPa. Its hard-anodized aluminium body is roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into tight machine frames 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 clipped on for end-of-stroke sensing. As a rule of thumb, plan on about 377 N of usable work at 0.5 MPa (roughly 60% of the rated push), which lifts about 32 kg vertically with a 2:1 margin. Note that the ACP family is discontinued: the current-production drop-in is the ISO 21287 ACE40X150, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE40X150SB (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 | 628 N | 572 N |
| 0.7 MPa | 880 N | 800 N |
| Max (@1.0 MPa) | 128 kgf | |
The ACE40X150SB 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). |
|---|---|
| 40 | Bore size in mm. |
| ×150 | 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 (adjustable stroke).
The 628.3 N push at 0.5 MPa clamps steel brackets and machined housings in milling jigs, and the short ISO 21287 body fits inside the fixture footprint.
A 150 mm stroke ejects cartons and trays between conveyor lanes at 30-500 mm/s, with CMSE or DMSE switches confirming each extend via the -S magnet.
Latches sliding machine guards on assembly lines, where the compact aluminium body mounts behind the frame and the male rod thread accepts a clevis knuckle.
For a 150 mm stroke in this force band, the 40 mm bore is the natural pick: 628.3 N push at 0.5 MPa. Step down to a 32 mm bore (402.1 N) if the load is lighter and space is tighter, or up to a 50 mm bore (981.7 N) when the work demands more muscle. The male rod thread (B) suits rod knuckles and external tooling; FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets bolt to the ISO 21287 face. Without air the piston drifts freely, so add a rod lock or pilot check valve if the load must stay put. Order the ACE40X150 as the current replacement and verify mounting dimensions first.
Replacement checklist
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N. At 0.7 MPa the push is 879.6 N and the pull 800.5 N. The theoretical maximum is 128.1 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), running on air filtered to 40 um at 30-500 mm/s.
No - the ACP family is discontinued. The current-production successor is the ACE40X150, an ISO 21287 compact cylinder in the same bore, stroke and force class with the same mounting family (FA/FB flange, LB foot, CA/CB clevis). Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. This model has a fixed TPU bumper at both ends and the optional -S magnet for CMSE / DMSE switches.
