This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE20X10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE20X10SB 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 ASP20X10SB
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP20X10SB is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø20mm bore and 10mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE20X10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP20X10SB
Single acting push cylinder with spring return: air extends the rod and an internal spring retracts it, so the ASP20X10SB runs on one air line and sits normally retracted at rest. This 20 mm bore, 10 mm stroke unit delivers 127.4 N of push at 0.5 MPa (190.2 N at 0.7 MPa), already net of the spring, and needs at least 0.2 MPa to overcome the spring. The male rod thread (B code) and the fitted -S magnet for CMSE / DMSE switches are built into this ordering code. Note that the ASP family is discontinued; the current-production replacement is the ASE20X10.
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 tight fixtures, small guarding and compact pick stations. A hard-anodized aluminium body with an S45C hard-chrome rod, fixed TPU bumpers at both ends, and a 50-500 mm/s speed range cover light clamping and ejection work. As a rule of thumb, plan on about 76 N (roughly 7.8 kg of vertical lift at 0.5 MPa with margin) for real work rather than the full rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE20X10SB (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 (Ø20mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 127.4 N |
| 0.7 MPa | 190.2 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 ASP20X10SB Is Used
Small-part press fit
The 127.4 N push at 0.5 MPa seats bearings or bushings into plastic housings on an electronics assembly bench, with the spring retracting the tool between cycles.
Position-checked ejection
With the fitted -S magnet, a DMSE switch confirms rod extension as the cylinder kicks a finished PCB carrier off a conveyor stop, all on a single air line.
Compact jig clamping
The short body, about 50% shorter than an ISO 15552 profile cylinder, clamps a bracket inside a cramped drilling fixture where a full-length body cannot fit.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP20X10SB with the ASE20X10SB
Size by force: at 0.5 MPa this 20 mm bore pushes 127.4 N net of the spring; step down to a 16 mm bore (78.4 N) for lighter loads or up to a 25 mm bore (210.1 N) if you need more margin. The spring retracts the rod on air loss and will not hold a mid-stroke position, so add an external stop if you need positive holding. This code carries the -S magnet (CMSE / DMSE switches can be mounted) and a male rod thread; flange, foot and clevis brackets fit the mounting face. Before ordering, confirm the ASE20X10 replacement matches your ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ASE20X10SB
- ✓ 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 ASP20X10SB FAQ
Push force is 127.4 N at 0.5 MPa and 190.2 N at 0.7 MPa, both already net of the return spring. Air extends the rod; the spring retracts it. Minimum working pressure is 0.2 MPa, operating range 0.2-1.0 MPa (28-145 psi), proof 1.5 MPa (215 psi), speed 50-500 mm/s, temperature -20 to +70 C, air filtered to 40 um.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot and CA/CB clevis brackets bolt to the same face. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly. The ASP is discontinued; the drop-in successor is the ASE20X10 - confirm ISO 21287 mounting dimensions before swapping.
