This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE20X15B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE20X15B 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 ATP20X15B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP20X15B is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø20mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE20X15B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP20X15B
The ATP20X15B is a single acting pull cylinder with spring return (discontinued): the spring extends the rod and compressed air retracts it, so the unit rests normally extended and fails to the extended position on air loss. At the 20 mm bore it delivers a net pull of 88.1 N at 0.5 MPa (135.2 N at 0.7 MPa, already net of the spring), and it needs at least 0.2 MPa of air to overcome the spring. The B code gives a male rod thread, and the air port is M5x0.8. This model is no longer in production; the current drop-in is the ATE20X15 (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 body is DIN-standard.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight jigs and guarded stations where a full-length body cannot. The hard-anodized aluminium body carries an S45C hard-chrome rod, and fixed TPU bumpers at both ends decelerate the travel. For sizing, plan on roughly 53 N of real work at 0.5 MPa (about 60% of the rating), which corresponds to lifting about 4 kg vertically with a 2:1 margin. Speed range is 50-500 mm/s over an operating pressure of 0.2-1.0 MPa (28-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE20X15B (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 (Ø20mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 88.1 N |
| 0.7 MPa | 135.2 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 ATP20X15B Is Used
Spring-extend part ejection
On a small electronics assembly press fixture, the spring pushes a formed connector out of its nest the moment air is lost, while the 88.1 N air pull retracts it for the next cycle.
Normally-out safety gate latch
A guarding interlock on a packaging machine stays latched by the extended rod; the 15 mm stroke pulls the latch back only while 0.2 MPa or more of air is present.
Sample tray indexing
A lab autosampler uses the short 15 mm pull to retract a tray stop between vials, where the compact body fits inside a tight enclosure that rules out a full-length profile cylinder.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP20X15B with the ATE20X15B
Size both ways: the 16 mm bore pulls 53.3 N at 0.5 MPa, while the 25 mm bore pulls 170.9 N - step up if your clamp or strip load exceeds the 88.1 N this bore offers. Remember the spring does not hold a mid-stroke position; on air loss the rod returns to its extended home. Mounting options are FA/FB flange, LB foot and CA/CB clevis. If you need position sensing, the optional -S magnet code enables CMSE / DMSE switches - this ATP20X15B has no magnet fitted, so no sensor can be mounted as ordered. Order the ATE20X15 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ATE20X15B
- ✓ 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 ATP20X15B FAQ
At 0.5 MPa the net pull is 88.1 N, and at 0.7 MPa it is 135.2 N - both figures are already net of the return spring, so no deduction is needed. Minimum working pressure is 0.2 MPa (28 psi), enough to beat the spring; operating range is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof pressure. Speed runs 50-500 mm/s over the 15 mm stroke, and the rod is 10 mm with a male thread (B code) on an M5x0.8 port.
Order the ATE20X15, the current-production ISO 21287 successor (swap the P for an E). It matches the same 20 mm bore, 15 mm stroke and force class, and it accepts the same FA/FB flange, LB foot and CA/CB clevis mounting family. Because this body is DIN-standard rather than ISO 21287, confirm the mounting dimensions against the ATE datasheet before swapping. If you also want position sensing, order the ATE with the optional -S magnet so CMSE / DMSE switches can be used.
