This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE100X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE100X20S 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 ASP100X20S
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP100X20S is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø100mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE100X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP100X20S
Single acting push cylinder with spring return, the AirTAC ASP100X20S extends its 25 mm rod with air and retracts on the spring, so one air line is all the plumbing it needs. At the 100 mm bore it delivers 3640.7 N of push at 0.5 MPa (5211.5 N at 0.7 MPa), already net of the spring, and it starts moving from just 0.2 MPa. 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 press fixtures and guarded stations. This model is discontinued; the current-production replacement is ASE100X20, so confirm ISO 21287 mounting dimensions before swapping.
Practical sizing: treat about 2184 N (roughly 0.6 of the rated push) as the usable working force at 0.5 MPa, which corresponds to lifting about 222 kg vertically - halve that to around 111 kg for a 2:1 margin on real part weights. The body is hard-anodized aluminium with an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and because this unit carries the -S code the magnet is fitted, so CMSE / DMSE switches can be mounted for end-of-stroke detection. Speed range is 50-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE100X20S (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 (Ø100mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 3640.7 N |
| 0.7 MPa | 5211.5 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 ASP100X20S Is Used
Pneumatic press station
The 3640.7 N push at 0.5 MPa over a 20 mm stroke suits short-travel staking, marking and swaging heads on small assembly presses.
Heavy clamp fixture
Spring retraction clears the clamp automatically on air loss, ideal for machining fixtures holding steel brackets or cast housings.
Ejector on packaging line
One air line and 50-500 mm/s speed make it a simple push-off for cartons or trays at a discharge conveyor.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP100X20S with the ASE100X20S
Size both ways before ordering: the 80 mm bore gives 2316.2 N at 0.5 MPa if your load is lighter, while this 100 mm bore's 3640.7 N suits heavier clamping or pressing. Remember the spring drives the rod home whenever air is lost, so it will not hold a mid-stroke position. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. Order ASE100X20 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ASE100X20S
- ✓ 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 ASP100X20S FAQ
Push is 3640.7 N at 0.5 MPa and 5211.5 N at 0.7 MPa, both already net of the return spring. Minimum working pressure is 0.2 MPa (28-145 psi operating range, 1.5 MPa / 215 psi proof). Air extends the rod, the spring retracts it, and speed runs 50-500 mm/s. Port is 1/4" (PT), rod thread is female M16x1.5.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits cramped jigs and guards. This -S version carries the magnet, so CMSE / DMSE reed or solid-state switches mount directly for end-of-stroke signalling. The model is discontinued; ASE100X20 is the current replacement - confirm ISO 21287 mounting dimensions before converting.
