This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE50X15B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE50X15B 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 ATP50X15B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP50X15B is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø50mm bore and 15mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE50X15B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP50X15B
A single acting pull cylinder with spring return, the ATP50X15B keeps the rod extended by its internal spring and retracts it with air pressure. At 0.5 MPa it pulls 775 N net of the spring, rising to 1127.5 N at 0.7 MPa, and it needs at least 0.2 MPa to overcome the spring. The 50 mm bore takes a 16 mm rod through a male thread (the B code) with a 1/8" PT port. This model is discontinued; the current-production replacement is the ATE50X15, so confirm the ISO 21287 mounting dimensions before you swap.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight clamping fixtures and retract-only tooling. As a planning figure, budget roughly 465 N (about 47 kg of force) for real work at 0.5 MPa, or expect it to lift about 39 kg vertically with a 2:1 margin. Air is filtered to 40 um, pressure runs 0.2-1.0 MPa (28-145 psi), speed 50-500 mm/s, and fixed TPU bumpers decelerate both ends. No magnet is fitted on this code; order the -S version if you need CMSE or DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE50X15B (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 (Ø50mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 775.0 N |
| 0.7 MPa | 1127.5 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 ATP50X15B Is Used
Clamp retraction on a machining fixture
The spring holds the clamp open and air pulls it clear at 775 N when the 50 mm bore is vented, clearing the part for loading on a CNC fixture.
Lifting a gate on packaging machinery
With about 39 kg of vertical lift capacity at a 2:1 margin, the 15 mm stroke raises small guards or gates and the spring drops them back extended on air loss.
Return stroke on an assembly press jig
Air retracts the tooling head between cycles while the spring extends it home, and the short body fits where a full-length ISO 15552 profile cylinder cannot.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP50X15B with the ATE50X15B
Size against the 0.5 MPa pull of 775 N: drop to the 40 mm bore (500.3 N) for lighter retraction tasks, or step up to the 63 mm bore (1320 N) when the load grows. Remember the spring returns the rod to its extended home position on air loss and will not hold a mid-stroke position. Mount with FA/FB flange, LB foot or CA/CB clevis brackets, and specify the -S code if position switches are planned. For new projects, order the ATE50X15 instead, as this ATP model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ATE50X15B
- ✓ 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 ATP50X15B FAQ
This 50 mm bore, 15 mm stroke model pulls 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, both figures net of the return spring. Operating pressure is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof pressure, minimum 0.2 MPa to move the rod, speed 50-500 mm/s, and a 1/8" PT port with a male rod thread on the 16 mm rod.
Order the ATE50X15, the current ISO 21287 successor made by swapping the P for an E. It matches the same bore, stroke and force class, but because the ATP was built to a DIN-standard compact format you should confirm the ISO 21287 mounting dimensions before swapping it into an existing fixture.
