This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE25X20SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE25X20SB 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 ATP25X20SB
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP25X20SB is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø25mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE25X20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP25X20SB
A single acting pull cylinder with spring return, the ATP25X20SB keeps the rod extended by spring force and retracts it with air pressure. At 0.5 MPa it pulls 170.9 N net of the spring (253.3 N at 0.7 MPa), and it needs at least 0.2 MPa to overcome the spring. This model is discontinued; the current-production successor is the ATE25X20, which matches the same bore, stroke and force class.
The 25 mm bore sits in a hard-anodized aluminium body with an S45C hard-chrome rod, and the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slips into tight jigs and guarding where a full-length body will not fit. Because the S code is ordered, the magnet is fitted and CMSE or DMSE switches can be mounted for end-of-stroke detection. As a planning figure, treat about 102 N (roughly 10 kg of pull) as the usable working force at 0.5 MPa, leaving margin for friction and seal drag.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE25X20SB (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 (Ø25mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 170.9 N |
| 0.7 MPa | 253.3 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 ATP25X20SB Is Used
Pick-up head retraction on small assembly cells
The spring holds a vacuum or gripper head lifted at rest; air at 0.5 MPa pulls it down 20 mm onto a connector or terminal. The 170.9 N net pull suits light plastic parts up to roughly 10 kg equivalent.
Position-verified gate latch on a test fixture
With the fitted -S magnet, a CMSE switch confirms the retracted position before a leak or electrical test starts. The 20 mm stroke clears a spring-loaded latch on PCB or wiring-harness fixtures.
Spring-extend clamping of machined housings
Air loss releases the clamp automatically, a fail-safe benefit on a small drilling or deburring station. The compact body mounts inside the fixture base plate where space is limited.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP25X20SB with the ATE25X20SB
Size the bore against the real pull: 170.9 N at 0.5 MPa here, versus 88.1 N for the 20 mm bore below it and 296.0 N for the 32 mm bore above it. If the load approaches the upper figure, step up to ATP32. Note that on air loss the spring returns the rod to its extended home position and no mid-stroke position is held. The male rod thread (B code) and PT ports suit direct fixture attachment, and FA/FB flange, LB foot or CA/CB clevis brackets match the mounting face. Before ordering, confirm the ATE25X20 replacement dimensions against your fixture, since the ATP follows the DIN-standard footprint.
Replacement checklist
- ✓ Current-production ACE → ATE25X20SB
- ✓ 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 ATP25X20SB FAQ
It is a single acting pull cylinder: the spring extends the rod and air retracts it. Net of the spring it pulls 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa. Minimum working pressure is 0.2 MPa, the operating range is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed is 50-500 mm/s, and the port is M5x0.8 with a 10 mm male rod thread.
No, the ATP family is discontinued. The current-production drop-in is the ATE25X20 (swap the P for an E), which offers the same 25 mm bore, 20 mm stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your existing fixture before swapping, because the ATP follows the DIN-standard footprint.
