This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE32X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE32X20B 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 ATP32X20B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP32X20B is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE32X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP32X20B
A single acting pull cylinder with spring return, the ATP32X20B uses its internal spring to hold the 12 mm rod extended and applies compressed air to retract it. At 0.5 MPa the net pull is 296 N, rising to 434.2 N at 0.7 MPa, both already net of the spring force, so the minimum 0.2 MPa (28-145 psi working band) is what it takes to beat the spring. The B code gives a male rod thread, the port is 1/8", and a fixed TPU bumper sits at each end of the hard-anodized aluminium body.
For sizing, treat roughly 178 N (about 0.6 of the 296 N rating) as the pull you can actually put to work at 0.5 MPa, which lifts about 15 kg vertically with a 2:1 margin. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures. Note this model is discontinued: the current-production drop-in is the ATE32X20, same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE32X20B (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 (Ø32mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 296.0 N |
| 0.7 MPa | 434.2 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 ATP32X20B Is Used
Spring-extended chuck retraction
Air pulls the 296 N (at 0.5 MPa) rod back to open a lathe chuck or collet closer; if air fails, the spring re-extends and the workpiece stays gripped.
Ejector on a small stamping die
The 20 mm stroke kicks finished brackets off a press die face; the spring resets the pin automatically between cycles at 50-500 mm/s.
Fail-safe gate return on a packaging line
A stopper gate on a bottle conveyor is held up by the spring and pulled down by air, so a power loss leaves the line blocked, not open.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP32X20B with the ATE32X20B
At 32 mm bore this sits mid-range: the 25 mm bore pulls 170.9 N at 0.5 MPa, while the 40 mm bore pulls 500.3 N, so step up if your clamp or retract load exceeds about 178 N of working pull. Strokes for this bore run short, and on air loss the spring always returns the rod to its extended home - it will not hold a mid-stroke position. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the same face, and if you need position sensing, order the -S version to enable CMSE / DMSE switches; this non-S unit carries no magnet. For new builds, specify the ATE32X20 instead, as this ATP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ATE32X20B
- ✓ 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 ATP32X20B FAQ
Net of the return spring: 296 N at 0.5 MPa and 434.2 N at 0.7 MPa. Operating range is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, temperature -20 to +70 C, speed 50-500 mm/s. Bore 32 mm, stroke 20 mm, rod 12 mm, 1/8" port, male rod thread (B code).
Order the ATE32X20, the current-production ISO 21287 successor: swap the P for an E and you get the same 32 mm bore, 20 mm stroke and spring-extend pull force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ATP follows the older DIN-standard footprint.
