This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE40X5 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE40X5 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 ASP40X5
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP40X5 is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø40mm bore and 5mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE40X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP40X5
This is a single acting push cylinder with spring return: compressed air extends the rod and an internal spring pulls it back home, so only one air line is needed. The 40 mm bore delivers 556.8 N of push at 0.5 MPa and 808.1 N at 0.7 MPa, both figures already net of the spring, and it starts working from just 0.2 MPa. ASP40X5 is discontinued; the current-production replacement is ASE40X5 (swap the P for an E), which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since this model follows the DIN-standard footprint.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped jigs and fixtures where a full-length body will not fit. For real-world sizing, expect about 334 N of usable push at 0.5 MPa, which lifts roughly 28 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the rod ends in a female M8x1.25 thread with a 1/8" air port. Note there is no magnet fitted - order the -S code if you want CMSE / DMSE switch capability.

Specifications follow the official AirTAC ACP datasheet (now discontinued).

Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø40mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 556.8 N |
| 0.7 MPa | 808.1 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 ASP40X5 Is Used
Drilled part ejection
A 5 mm kick from the 12 mm rod pops a finished bushing out of a drill jig, with the spring retracting the pin so the next blank can drop in.
Weld fixture clamping
The 556.8 N push at 0.5 MPa holds a thin bracket against a stop during spot welding, and the spring releases it instantly when air is cut.
Carton flap tuck
On a packaging line the short-stroke push nudges a carton flap into place before taping, fitting into the tight space beside the tape head.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP40X5 with the ASE40X5
Check the force both ways: the 32 mm bore gives 352.5 N at 0.5 MPa, while stepping up to the 50 mm bore raises it to 875.5 N. If your part needs 556.8 N at 0.5 MPa, ASP40X5 is the match. Remember that on air loss the spring drives the rod fully retracted - it will not hold a mid-stroke position, so plan your rest state accordingly. Mounting options are FA/FB flange, LB foot and CA/CB clevis, and the optional -S magnet enables CMSE / DMSE switches for end-of-stroke sensing. For new projects, specify ASE40X5 instead, as this model is out of production.
Replacement checklist
- ✓ Current-production ACE → ASE40X5
- ✓ 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 ASP40X5 FAQ
At 0.5 MPa the push force is 556.8 N, and at 0.7 MPa it reaches 808.1 N - both already net of the return spring, so no derating for the spring is needed. Working pressure spans 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed runs 50-500 mm/s, and the bore is 40 mm with a 5 mm stroke, 12 mm rod, 1/8" port and female M8x1.25 rod thread.
Order ASE40X5, the ISO 21287 successor made by swapping the P for an E. It is the current-production drop-in with the same 40 mm bore, 5 mm stroke and force class, plus the same FA/FB flange, LB foot and CA/CB clevis mounting family. Because this older model follows the DIN-standard footprint, verify the ISO 21287 mounting dimensions against your fixture before the swap.
