This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE50X25 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE50X25 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 ATP50X25
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP50X25 is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø50mm bore and 25mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE50X25 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP50X25
This is a single acting pull cylinder: an internal spring holds the rod extended and compressed air at 0.2 MPa or more retracts it, so the 50 mm bore delivers a net pull of 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, spring already deducted. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits shallow jigs and guard panels. Note that this ATP model is discontinued; the current-production successor is the ATE50X25, a drop-in in the same bore, stroke and force class.
In practice, budget roughly 465 N (about 47 kg of pull) for real work at 0.5 MPa instead of the full rating, and expect the spring to lift about 39 kg vertically with a 2:1 margin. The rod is 16 mm S45C hard-chrome steel with a female M10x1.5 thread, the air port is 1/8" PT, and a fixed TPU bumper pads both ends. The magnet is not fitted on this code; order the optional -S version if you need CMSE or DMSE switch feedback.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE50X25 (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 ATP50X25 Is Used
Carton hold-down on a case packer
The spring keeps the pad pressed on the carton flap while air retracts it to release; 775 N at 0.5 MPa is ample for 300 mm corrugated boxes, and the 25 mm stroke clears the transfer rail.
Spring-clamped drill jig gate
A fixture gate that must stay closed when air fails suits this normally-extended pull action; the short body mounts inside the jig frame where a full-length profile cylinder will not fit.
Belt-tension take-up arm
The spring pulls a tension roller against a conveyor belt continuously; with about 47 kg of usable pull at 0.5 MPa, a regulator sets belt tension without extra hardware.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP50X25 with the ATE50X25
Right-size against neighbours: the 40 mm bore pulls 500.3 N at 0.5 MPa, while stepping up to 63 mm gives 1320 N, so choose the 50 mm when your clamp or strip load sits between those figures. Because the spring returns the rod on air loss, it will not hold a mid-stroke position - plan your rest state as extended. FA/FB flange, LB foot and CA/CB clevis brackets bolt straight to the face, and the optional -S magnet enables CMSE / DMSE switches. For new projects, order the ATE50X25 instead and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ATE50X25
- ✓ 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 ATP50X25 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. Working 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 fluid is air filtered to 40 um. The 0.2 MPa minimum is what it takes to beat the spring and start the retract stroke.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and fixtures. Switches are not possible on this exact code because no magnet is fitted; order the optional -S version to enable CMSE or DMSE reed or solid-state switches. Also note this model is discontinued - the ATE50X25 is the current drop-in, so confirm the ISO 21287 mounting dimensions before you swap.
