This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE32X20SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE32X20SB 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 ATP32X20SB
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP32X20SB 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 ATE32X20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP32X20SB
A single acting pull cylinder, the ATP32X20SB keeps its rod extended by an internal spring and retracts it with compressed air, so the assembly fails to the extended home position whenever air is lost. The 32 mm bore delivers a net pull of 296 N at 0.5 MPa (434.2 N at 0.7 MPa, already minus the spring), and 0.2 MPa is the minimum working pressure needed to overcome the spring. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs, guards and gantries. In practice, plan on roughly 178 N of usable pull at 0.5 MPa, which lifts about 15 kg vertically with a 2:1 margin - enough to release a 12 kg clamping slide or retract a gate. Note this ATP family is discontinued; the current-production replacement is the ATE32X20, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE32X20SB (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 ATP32X20SB Is Used
Spring-out clamping slide
The spring holds a fixture clamp extended at 296 N net pull; air retracts it between cycles on a small CNC jig, and the 20 mm stroke suits short clamp travel.
Sensed gate release on a packaging line
With the -S magnet fitted, a DMSE switch confirms the rod is home before a carton pusher cycles, preventing jam-ups at a case erector.
Fail-safe latch retraction
On a conveyor divert gate, air loss springs the latch back to its extended safe position - about 15 kg vertical equivalent at a 2:1 margin.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP32X20SB with the ATE32X20SB
Size by pull, not push: at 0.5 MPa this bore nets 296 N, while the 25 mm bore gives 170.9 N and the 40 mm bore 500.3 N - step up if your mechanism needs more than about 178 N of real work. The spring returns the rod fully on air loss and will not hold a mid-stroke position, so add a separate stop if you need intermediate holding. This SB code has a male rod thread and the -S magnet fitted; pair it with CMSE or DMSE switches and FA/FB flange, LB foot or CA/CB clevis mounts. For new projects, order the ATE32X20 instead - this ATP model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ATE32X20SB
- ✓ 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 ATP32X20SB FAQ
Net of the return spring, the 32 mm bore pulls 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, speed 50-500 mm/s, and temperature -20 to +70 C. The spring extends the rod and air retracts it; on air loss the rod returns fully extended and no mid-stroke position is held.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length cylinder cannot. The SB code means a male rod thread plus the optional -S magnet, allowing CMSE or DMSE switches; both ends carry a fixed TPU bumper. This model is discontinued - the current drop-in is the ATE32X20, so confirm the ISO 21287 mounting dimensions before ordering.
