This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE40X5B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE40X5B 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 ASP40X5B
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP40X5B 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 ASE40X5B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP40X5B
The ASP40X5B is a single acting push cylinder with spring return: air extends the 12 mm rod and the spring retracts it, so one air line is all the plumbing needs. At 0.5 MPa it delivers 556.8 N of push force net of the spring (808.1 N at 0.7 MPa), and it starts working from just 0.2 MPa. This model is discontinued; the current-production replacement is the ASE40X5, which keeps the same bore, stroke and force class.
The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping nests and guarded assemblies. In practice, plan on about 334 N of usable work at 0.5 MPa, which corresponds to lifting roughly 28 kg vertically with a 2:1 margin. The male rod thread (B code) bolts straight to I/Y knuckles, and a fixed TPU bumper decelerates the rod at both ends.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE40X5B (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 (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 ASP40X5B Is Used
Bearing press-fit staging
A 5 mm stroke is ideal for pre-seating small bearings into housings on an assembly bench; 556.8 N at 0.5 MPa handles light interference fits before final pressing.
Presence clamping on a PCB test fixture
The spring return lifts the clamp the moment air drops, releasing the board automatically - useful where operators must retrieve parts after every cycle.
Dispense valve actuation
Short-trust push action toggles a micro-dispense valve or sample gate in lab equipment, with the 1/8" port keeping tubing runs simple.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP40X5B with the ASE40X5B
Size against neighbours: the 32 mm bore gives 352.5 N at 0.5 MPa, while stepping up to the 50 mm bore reaches 875.5 N - pick the 40 mm when your clamp load sits between those. Because the spring drives the rod home on air loss, this cylinder retracts to its rest position rather than holding a mid-stroke load. If you need position sensing, order the -S variant with the optional magnet for CMSE / DMSE switches; the plain ASP40X5B carries no magnet. Before swapping to the ASE40X5, confirm the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ASE40X5B
- ✓ 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 ASP40X5B FAQ
Push force is 556.8 N at 0.5 MPa and 808.1 N at 0.7 MPa, both already net of the return spring. Working pressure is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof rating; 0.2 MPa is the minimum to overcome the spring. Air must be filtered to 40 um, speed range is 50-500 mm/s, and temperature spans -20 to +70 C.
The ISO 21287 short body cuts mounting length by about 50% versus an ISO 15552 profile cylinder, so it fits shallow fixtures. If air is lost, the return spring drives the rod back to its retracted home position - it does not hold a mid-stroke load. A fixed TPU bumper decelerates the rod at each end. This model is discontinued; the ASE40X5 is the current drop-in, so verify ISO 21287 mounting dimensions before converting.
