This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE12X5SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE12X5SB 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.
Airtac ASP Single Acting Guided Compact Cylinder ASP12X5SB
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP12X5SB is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø12mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE12X5SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP12X5SB
A single acting push cylinder with spring return, the ASP12X5SB extends its 6 mm rod with air and retracts on the built-in spring, so one air line is all the plumbing a 5 mm stroke needs. At 0.5 MPa it delivers 40 N net of the spring (62.7 N at 0.7 MPa), and it starts moving from just 0.2 MPa (28-145 psi working band, 1.5 MPa proof). The -S magnet this model carries lets you clip CMSE or DMSE switches straight onto the body for end-of-stroke sensing.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim pick-and-place heads and micro clamping fixtures. For sizing, 40 N at 0.5 MPa is about a 4 kg force class; keep real work near 24 N and expect roughly 2 kg of vertical lift with a 2:1 margin. Note this model is discontinued - the current-production replacement is the ASE12X5, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE12X5SB (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 (Ø12mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 40.0 N |
| 0.7 MPa | 62.7 N |
Single-acting push: air extends the rod; the return spring retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ASP Single Acting Guided Compact Cylinder ASP12X5SB Is Used
Micro part ejection
A 5 mm kick from the 6 mm rod nudges small machined or moulded parts off a nest; 40 N at 0.5 MPa clears chips and light parts, and the spring returns the pin when air drops.
Sensor probe advance
Short-stroke presence checks on an electronics assembly line: air extends the probe, the -S magnet trips a CMSE switch at the extended position, and the spring retracts it between cycles.
Light hold-down clamp
Clamping thin PCBs or small brackets in a test fixture - about 24 N of usable force at 0.5 MPa holds light workpieces, and the short body fits inside the fixture plate.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP12X5SB with the ASE12X5SB
At 12 mm bore this sits at the bottom of the range: 40 N push at 0.5 MPa net of the spring. If your part weighs more than about 2 kg to lift or your clamp needs over 24 N of real work, step up to the 16 mm bore (78.4 N at 0.5 MPa) or 20 mm (127.4 N); if 40 N is generous, there is nothing smaller in the family. The male rod thread (B code) takes an I/Y knuckle directly, and the PT port is M5x0.8. On air loss the spring drives the rod home retracted - it will not hold a mid-stroke position. Order the ASE12X5 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ASE12X5SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ASP Single Acting Guided Compact Cylinder ASP12X5SB FAQ
Push force, already net of the return spring: 40 N at 0.5 MPa and 62.7 N at 0.7 MPa on the 12 mm bore. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed 50-500 mm/s, temperature -20 to +70 C, and air filtered to 40 um. Below 0.2 MPa the spring wins and the rod stays retracted.
The short ISO 21287-class body cuts mounting length by about half versus an ISO 15552 profile cylinder, with a fixed TPU bumper at each end. This -S version carries the optional magnet, so CMSE / DMSE reed or solid-state switches mount on the body. The model is discontinued; the current-production ASE12X5 is the drop-in successor - confirm ISO 21287 mounting dimensions before you swap.
