This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE40X5 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE40X5 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 ATP Single Acting Port Compact Cylinder ATP40X5
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP40X5 is a single acting, pull (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 ATE40X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP40X5
A single acting pull cylinder with spring return (discontinued), the ATP40X5 uses a 40 mm bore and a very short 5 mm stroke: the internal spring holds the rod extended, and compressed air retracts it. At 0.5 MPa the net pull is 500.3 N (729 N at 0.7 MPa), already deducted for the spring, and 0.2 MPa is the minimum working pressure needed to overcome the spring. The hard-anodized aluminium ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures where a full-length body will not fit.
For sizing, treat roughly 300 N (about 0.6 of the 500.3 N rating) as the usable pull at 0.5 MPa, which corresponds to lifting about 25 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, the rod is S45C hard-chrome steel with a female M8x1.25 thread, and the 1/8" port is set by the 40 mm bore. This model is discontinued: the current-production drop-in is the ATE40X5 (swap the P for an E), so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE40X5 (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 | Pull force (spring return) |
|---|---|
| 0.5 MPa | 500.3 N |
| 0.7 MPa | 729.0 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ATP Single Acting Port Compact Cylinder ATP40X5 Is Used
Fixture gate retraction
On a CNC jig, the spring-extended rod keeps a 5 mm swing gate or locator open at rest; 500.3 N of air pull at 0.5 MPa retracts it only while the clamp cycle runs.
Ejector pin return
A short-stroke ejector on a small plastics or die-cast tool: the spring pushes the pin out home, and the 40 mm bore pulls it back the 5 mm needed to clear the part.
Presence check with switch feedback
Order the -S code to add the magnet, then a CMSE or DMSE switch confirms the rod has retracted on a packaging line check station; without -S no magnet is fitted.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP40X5 with the ATE40X5
Size both ways: if 500.3 N at 0.5 MPa is more than the job needs, the ATP32X5 delivers 296.0 N in the same short body; if the load grows, the ATP50X5 pulls 775.0 N. Remember the spring returns the rod to its extended home on air loss and will not hold a mid-stroke position. FA/FB flange, LB foot and CA/CB clevis brackets bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches (without -S there is no magnet). The ATP40X5 is discontinued - order the ATE40X5 as the current ISO 21287 drop-in and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ATE40X5
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ATP Single Acting Port Compact Cylinder ATP40X5 FAQ
Net pull (already deducting the return spring) is 500.3 N at 0.5 MPa and 729 N at 0.7 MPa. Operating range is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure; 0.2 MPa is the minimum needed to beat the spring. Speed is 50-500 mm/s, temperature -20 to +70 C, and air must be filtered to 40 um. The spring extends the rod; air retracts it.
It is an ISO 21287 short-body cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options and a fixed TPU bumper at both ends. The ATP40X5 is discontinued; the ATE40X5 is the current-production drop-in in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
