This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE50X5 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE50X5 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 ASP50X5
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP50X5 is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø50mm bore and 5mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE50X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP50X5
A single acting push cylinder with spring return, the ASP50X5 uses a 50 mm bore and a very short 5 mm stroke: air extends the rod, then the internal spring pulls it back home when pressure drops. At 0.5 MPa it delivers 875.5 N of push already net of the spring (1268.2 N at 0.7 MPa), and it needs only 0.2 MPa minimum and one air line to run. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped fixtures where a full-length body will not fit.
In practice, plan on roughly 525 N of usable push at 0.5 MPa, which is about 53 kgf - so this bore comfortably lifts around 44 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a fixed TPU bumper at both ends, the 16 mm S45C hard-chrome rod ends in a female M10x1.5 thread, and the air port is 1/8". Note this model is discontinued: the current-production drop-in is the ASE50X5 (swap the P for an E), so confirm ISO 21287 mounting dimensions before you swap. The magnet is the optional -S code; without it no CMSE / DMSE switch can be fitted.

Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø50mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 875.5 N |
| 0.7 MPa | 1268.2 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 ASP50X5 Is Used
Bench-top stamping fixture
The 875.5 N push at 0.5 MPa over a 5 mm stroke is enough to seat small terminals or rivets in an electronics assembly jig, with the spring retracting the tool instantly on air-off.
Injection mold gate eject
A short-stroke ejector on a small mold: air extends the pin to release the part, the return spring clears the cavity automatically, and the compact body fits behind the mold plate.
Carton hold-down clamp
On a packaging line, the rod presses a flap or label down for about 44 kg of vertical equivalent force while glue cures, then springs back to clear the passing carton.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP50X5 with the ASE50X5
Size by force, not bore alone: a 40 mm bore gives 556.8 N at 0.5 MPa while a 63 mm bore reaches 1420.5 N, so the 50 mm sits in the middle at 875.5 N. If your clamp or eject needs only a few millimetres of travel and one solenoid valve, this single acting push layout keeps plumbing simple. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches. This model is discontinued - order the ASE50X5 as the current drop-in and verify ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ASE50X5
- ✓ 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 ASP50X5 FAQ
Push force is 875.5 N at 0.5 MPa and 1268.2 N at 0.7 MPa, both already net of the return spring. Operating pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 50-500 mm/s, and temperature -20 to +70 C. The 50 mm bore drives a 16 mm rod through a 5 mm stroke from a single 1/8" port.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guards. It is single acting push with spring return: if air is lost the spring drives the rod back to its retracted home position, it does not hold a mid-stroke position. A fixed TPU bumper decelerates the rod at each end, and mounting options are FA/FB flange, LB foot and CA/CB clevis. The model is discontinued - the ASE50X5 is the current drop-in.
