This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE40X15SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE40X15SB 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 ATP40X15SB
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP40X15SB is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø40mm bore and 15mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE40X15SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP40X15SB
Single acting pull cylinder with spring return: the spring extends the rod and compressed air retracts it, so the ATP40X15SB sits normally extended and fails to the extended position on air loss. This 40 mm bore unit delivers 500.3 N of pull at 0.5 MPa and 729 N at 0.7 MPa, both figures already net of the return spring, with a 15 mm stroke and a male rod thread on the B code. The minimum working pressure is 0.2 MPa, the pressure range is 0.2-1.0 MPa (28-145 psi) and speed runs 50-500 mm/s.
The short ISO 21287 style body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into tight jigs and guarding where a full-length body will not fit. Because the S code is present, the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke signalling. Note this model is discontinued: the current-production replacement is the ATE40X15, which matches the same bore, stroke and force class. As a sizing rule, plan on roughly 300 N of real work at 0.5 MPa, which lifts about 25 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE40X15SB (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 ATP40X15SB Is Used
Spring-up lift gate on a packaging machine
The spring holds a small guard or gate raised; air pulls it down for each cycle. 500.3 N at 0.5 MPa lifts about 25 kg with margin, and the 15 mm stroke suits short travel.
Position-signalled clamp in an electronics fixture
With the -S magnet fitted, a DMSE switch confirms the retracted position. The short body tucks into dense fixture plates where a full-length profile cylinder cannot.
Normally-extended ejector on an assembly station
On air loss the part stays ejected, a safe fail state for manual loading. The male rod thread bolts straight to a custom pusher tip.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP40X15SB with the ATE40X15SB
Size by pull force, not push force: this bore gives 500.3 N at 0.5 MPa net of the spring, while the smaller 32 mm bore offers 296.0 N and the larger 50 mm bore reaches 775.0 N at the same pressure. If your application must hold a mid-stroke position, look elsewhere - on air loss the spring simply returns the rod to its extended home. The male rod thread suits rod knuckles and tooling plates, and FA/FB flange, LB foot or CA/CB clevis mounting can be specified. Confirm the ISO 21287 mounting dimensions of the ATE40X15 replacement before swapping.
Replacement checklist
- ✓ Current-production ACE → ATE40X15SB
- ✓ 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 ATP40X15SB FAQ
At 0.5 MPa the pull is 500.3 N and at 0.7 MPa it is 729 N, both already net of the return spring. The spring extends the rod and air retracts it, so at least 0.2 MPa is needed to overcome the spring. Operating range is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 50-500 mm/s, port 1/8" and rod 12 mm with a male thread on this B code.
No, the ATP family is discontinued. The current-production drop-in is the ATE40X15, which keeps the same 40 mm bore, 15 mm stroke and force class in the ISO 21287 short body. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, and remember the -S magnet on this unit enables CMSE or DMSE switches.
