This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE80X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE80X20B 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 ATP80X20B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP80X20B is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø80mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE80X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP80X20B
A single acting pull cylinder with spring extend, the ATP80X20B keeps its 80 mm rod normally out and uses compressed air to retract it. At 0.5 MPa the net pull is 2159.1 N after the return spring takes its share, rising to 3101.6 N at 0.7 MPa, so it suits short-stroke clamping and pressing checks on medium-heavy tooling. Minimum working pressure is 0.2 MPa, the band is 0.2-1.0 MPa (28-145 psi), and speed runs 50-500 mm/s.
The hard-anodized aluminium body follows the ISO 21287 short format, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, which helps when a guard or fixture leaves little room. For sizing, treat about 1295 N (roughly 110 kg lifted vertically with a 2:1 margin) as the realistic working pull at 0.5 MPa. Note the B code gives a male rod thread on the 20 mm rod, the port is 1/4", and this model is discontinued - the current drop-in is the ATE80X20, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE80X20B (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 (Ø80mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 2159.1 N |
| 0.7 MPa | 3101.6 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 ATP80X20B Is Used
Clamp fixture on a CNC machining center
The spring-extended rod holds a vise jaw or swing clamp closed at rest, and 2159.1 N of net pull at 0.5 MPa retracts it for part changeover on aluminum housings.
Ejector on a stamping die
A 20 mm stroke is enough to kick thin stamped brackets off the die face, and the spring pushes the ejector plate back out the moment air pressure drops.
Case reject pusher on a filling line
Mounted on an LB foot bracket, the cylinder pulls a deflector plate across a conveyor lane to divert underfilled cartons, retracting in under 0.4 s at 50-500 mm/s.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP80X20B with the ATE80X20B
Size by net pull: this 80 mm bore delivers 2159.1 N at 0.5 MPa, while a 63 mm bore gives 1320 N and a 100 mm bore reaches 3395.3 N at the same pressure. On air loss the spring returns the rod to its extended home position and will not hold a mid-stroke point, so add an external stop if the process needs one. The 20 mm stroke sits inside the standard range for this bore. Choose FA/FB flange, LB foot or CA/CB clevis mounts to suit the fixture, and if position detection is needed order the -S code, since without it no magnet is fitted and CMSE / DMSE switches cannot be used. For new projects specify the ATE80X20, the current-production successor.
Replacement checklist
- ✓ Current-production ACE → ATE80X20B
- ✓ 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 ATP80X20B FAQ
Net of the return spring, the pull is 2159.1 N at 0.5 MPa and 3101.6 N at 0.7 MPa. The spring extends the rod and air retracts it, so at least 0.2 MPa is needed to move the rod against the spring. Operating range is 0.2-1.0 MPa (28-145 psi), proof pressure is 1.5 MPa (215 psi), fluid is air filtered to 40 um, and speed is 50-500 mm/s.
Sensors work only when the optional -S magnet is ordered; this version has no magnet, so CMSE or DMSE switches cannot be read. The ATP family is discontinued, and the current-production replacement is the ATE80X20, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, and use FA/FB flange, LB foot or CA/CB clevis brackets on either body.
