This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE50X15S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE50X15S 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 ATP50X15S
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP50X15S 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 ATE50X15S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP50X15S
Single acting pull cylinder of DIN-standard compact build, the ATP50X15S uses an internal spring to extend the rod while compressed air retracts it, so the unit rests normally extended and fails to the extended position on air loss. With its 50 mm bore it delivers a net pull of 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, already subtracting the spring force, and it needs at least 0.2 MPa to overcome the spring. The hard-anodized aluminium body with an S45C hard-chrome rod keeps the short ISO 21287-class footprint, which saves roughly 50% of the mounting length of an ISO 15552 profile cylinder.
Because the S code is in this model, the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. Plan on about 465 N of real work at 0.5 MPa, which is roughly 24 kg of vertical lift with a 2:1 margin, enough for clamping or retracting a small fixture. Note that this model is discontinued: the current-production drop-in is the ATE50X15, same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE50X15S (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 ATP50X15S Is Used
Spring-open clamp on a CNC fixture
Air retracts the clamp arm to release a machined aluminium housing; if air fails, the spring extends and the part stays clamped at 775 N net pull.
Retract a gate on a bottling line
The 15 mm stroke pulls a divert gate back at 50-500 mm/s between two guide rails, with the TPU bumpers absorbing the end-of-travel stop.
Position feedback on a test rig
With the fitted -S magnet, a DMSE switch signals the retracted position of a spring-extended probe holder on an electronics leak-test station.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP50X15S with the ATE50X15S
Size the pull force both ways: the 40 mm bore gives 500.3 N at 0.5 MPa, while the 63 mm bore reaches 1320 N, so the 50 mm sits squarely between them at 775 N. If your job needs a held mid-stroke position, this spring-return pull type will not provide it - on air loss the spring returns the rod to its extended home. Mounting options are FA/FB flange, LB foot and CA/CB clevis, and the female M10x1.5 rod thread takes standard I/Y knuckles. This model is discontinued; order the ATE50X15 as the current ISO 21287 replacement and verify mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ATE50X15S
- ✓ 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 ATP50X15S FAQ
Net of the return spring, the 50 mm bore pulls 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), speed 50-500 mm/s, temperature -20 to +70 C, and the air must be filtered to 40 um. The spring extends the rod; air retracts it, and the unit fails to extended on air loss.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guards. This S-coded model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount directly on the body. It is discontinued - the ATE50X15 is the current drop-in, so confirm ISO 21287 mounting dimensions before ordering.
