This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X150SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X150SB 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 ACP20X150SB is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X150SB (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP20X150SB is a double acting DIN-standard compact cylinder with a 20 mm bore and a made-to-order 150 mm stroke - longer than the 100 mm standard maximum for this bore. Pushing with 157.1 N and pulling with 117.8 N at 0.5 MPa (219.9 N / 164.9 N at 0.7 MPa), it suits small clamping and lifting jobs. The male rod thread (B code) and the fitted -S magnet for CMSE / DMSE switches are built into this ordering code. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight fixtures and guarding.
Because roughly 60% of the push rating is a realistic working figure, plan on about 94 N of usable force at 0.5 MPa - enough to lift about 16 kg vertically, or about 8 kg with a 2:1 margin. The hard-anodized aluminium body carries a fixed TPU bumper at each end, and the S45C hard-chrome rod runs on a two-way grease-storing piston seal. Note this model is discontinued: the current-production drop-in is ACE20X150, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X150SB (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 | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
The ACE20X150SB 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). |
|---|---|
| 20 | 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 157.1 N push at 0.5 MPa ejects finished connectors or caps from nests, and the 150 mm stroke clears deep pockets where a standard 100 mm stroke would not reach.
With about 8 kg of vertical lift at a 2:1 margin, the 20 mm bore raises microplate carriers inside tight instrument frames, and the -S magnet feeds CMSE switch positions to the controller.
The short body fits under low guarding, pressing flaps during taping at 30-500 mm/s, with the male rod thread taking a knuckle for slightly off-axis contact.
Size both ways: a 16 mm bore gives 100.5 N push at 0.5 MPa if the load is lighter, while a 25 mm bore raises it to 245.4 N for heavier clamps. The 150 mm stroke is non-standard for bore 20 (max standard 100 mm), so it is quoted as made to order. A plain cylinder like this drifts when air is lost - add a rod lock or pilot check valve if the load must hold. The male rod thread suits I/Y knuckles, and FA/FB flange, LB foot or CA/CB clevis mountings bolt to the same face. Order ACE20X150 as the current replacement.
Replacement checklist
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push is 219.9 N and pull 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It is double acting, 20 mm bore with a 10 mm rod, M5x0.8 ports, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and a fixed TPU bumper at both ends. The 150 mm stroke is made to order.
Order ACE20X150, the ISO 21287 successor in the same bore, stroke and force class. The ACP is DIN-standard, so confirm the ISO 21287 mounting dimensions before swapping. This code already carries the -S magnet and male rod thread, so match those options on the ACE order.
