This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE40X5B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE40X5B 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 ATP40X5B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP40X5B 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 ATE40X5B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP40X5B
A single acting pull cylinder with spring return, the ATP40X5B keeps its 12 mm rod extended by spring and uses compressed air to retract it over a short 5 mm stroke. At 0.5 MPa the net pull is 500.3 N (729 N at 0.7 MPa, already after the spring), and at least 0.2 MPa (28-145 psi working band) is needed to overcome the spring. The B code gives a male rod thread and the PT port is 1/8". This model is discontinued; the current-production drop-in is the ATE40X5 (swap the P for an E), so confirm ISO 21287 mounting dimensions before swapping.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixture plates and guarding where a full-length body cannot. For real-world sizing, treat roughly 300 N as the usable pull at 0.5 MPa - about 30 kg of working force - or plan on lifting about 25 kg vertically with a 2:1 margin (the raw 500.3 N equals roughly 51 kgf). A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the optional -S magnet enables CMSE / DMSE switches; without -S there is no magnet.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE40X5B (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 ATP40X5B Is Used
Spring-extend locating pin on CNC fixtures
The spring pushes the 12 mm pin out into a bushing; 500.3 N of air pull at 0.5 MPa retracts it 5 mm before part changeover, and a power cut leaves the pin safely out.
Fail-safe lid lift on a tray sealer
Spring extension raises the sealing head guard at rest; air pulls it down 5 mm only while the machine is running, meeting a fail-to-extended safety requirement.
Conveyor stopper blade return
A short 5 mm retract pulls the stopper blade clear of passing cartons at up to 500 mm/s, with the spring re-extending it to block flow the moment air is lost.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP40X5B with the ATE40X5B
Size by net pull: if 500.3 N at 0.5 MPa is marginal, step up to bore 50 for 775 N; if it is generous, bore 32 delivers 296 N in a smaller envelope. Remember the spring returns the rod to its extended home on air loss and never holds a mid-stroke position. Bolt the body on with FA/FB flange, LB foot or CA/CB clevis mounts, and order the -S code only if CMSE / DMSE position switches are needed. For new builds, specify the ATE40X5 instead - this ATP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ATE40X5B
- ✓ 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 ATP40X5B FAQ
Net of the return spring, the 40 mm bore pulls 500.3 N at 0.5 MPa and 729 N at 0.7 MPa. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, air filtered to 40 um, speed 50-500 mm/s, and temperature -20 to +70 C. The spring, not air, extends the rod, so at least 0.2 MPa is required before retraction begins.
Order the ATE40X5, the current ISO 21287 successor: swap the P for an E and you get the same 40 mm bore, 5 mm stroke and force class in a short compact body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. Confirm the ISO 21287 mounting dimensions against your fixture first, and note the magnet is only present when the -S code is ordered.
