This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE63X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE63X20S 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 ASP63X20S
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP63X20S is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø63mm bore and 20mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE63X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP63X20S
Single acting push cylinder with spring return: air extends the rod and the built-in spring pulls it back to the retracted home position, so only one air line is needed. At the 63 mm bore this model delivers 1420.5 N of push at 0.5 MPa (2044 N at 0.7 MPa), figures already net of the return spring, and it starts working from just 0.2 MPa. The hard-anodized aluminium body in the short ISO 21287 format saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarded assemblies.
The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. A fixed TPU bumper at each end decelerates the rod, and the S45C hard-chrome rod carries a female M10x1.5 thread. Note that this model is discontinued: the current-production drop-in is the ASE63X20, so confirm the ISO 21287 mounting dimensions before swapping. As a sizing rule, keep real work near 852 N (about 0.6 of the 0.5 MPa push), which corresponds to lifting roughly 72 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE63X20S (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 (Ø63mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 1420.5 N |
| 0.7 MPa | 2044.0 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 ASP63X20S Is Used
Carton clamp on a case packer
The 1420.5 N push at 0.5 MPa squares carton stacks before taping, and the spring return clears the clamp the moment air drops.
Ejector on a stamping press feed
A 20 mm stroke kicks scrap off the die table at up to 500 mm/s, with the spring retracting the pusher between cycles.
Presence check on an assembly line
With the fitted -S magnet driving a DMSE switch, the PLC confirms the part was pushed home every cycle.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP63X20S with the ASE63X20S
Size by force first: if 1420.5 N at 0.5 MPa is more than your jig needs, the 50 mm bore gives 875.5 N, while stepping up to 80 mm raises it to 2316.2 N. Remember the spring drives the rod home whenever air is lost, so this cylinder will not hold a mid-stroke position under load. Match FA/FB flange, LB foot or CA/CB clevis mounting to your fixture, and keep the -S magnet in mind if CMSE / DMSE switching is planned. Order the ASE63X20 as the current replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ASE63X20S
- ✓ 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 ASP63X20S FAQ
At 0.5 MPa it pushes with 1420.5 N, rising to 2044 N at 0.7 MPa; both figures are net of the return spring. Working range is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 50-500 mm/s, air filtered to 40 um, and -20 to +70 C operation. The rod is 16 mm with a female M10x1.5 thread and the air port is 1/8" PT.
The short ISO 21287 format body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded frames. This model already carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount directly for end-of-stroke detection. Since the model is discontinued, order the ASE63X20 replacement and confirm the ISO 21287 mounting dimensions before the swap.
