This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE50X25SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE50X25SB 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 ATP50X25SB
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP50X25SB 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 ATE50X25SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP50X25SB
The ATP50X25SB is a single acting pull cylinder with spring return: an internal spring holds the rod extended and compressed air retracts it, so at rest the rod sits out and on air loss it fails to the extended home position. It is a DIN-standard compact body, not a full-length profile unit, and the short ISO 21287-class construction saves about 50% of the mounting length of an ISO 15552 profile cylinder - useful in tight jigs, guards and gantries. Net of the spring, the 50 mm bore pulls 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa needed to overcome the spring.
Plan your real workload below the rating: at 0.5 MPa the usable pull is roughly 465 N, which corresponds to lifting about 39 kg vertically with a 2:1 margin. The rod end carries a male thread (the B code) and the air port is 1/8". This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke signalling. The ATP family is discontinued; the current-production drop-in is the ATE50X25 (swap the P for an E), which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since this unit is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE50X25SB (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 ATP50X25SB Is Used
Spring-extended clamp on a CNC fixture
The spring keeps the clamp jaw closed on an aluminium billet while the operator loads it; 775 N of pull at 0.5 MPa retracts the jaw for part changeover, and air loss fails safe to clamped.
Retracting a gate on a bottling line
Mounted under a conveyor guard, the 25 mm stroke pulls a divert gate back against the spring; the short body fits where a full-length profile cylinder would not.
Position-flagged lift assist in electronics assembly
With the -S magnet and a DMSE switch, the PLC confirms the rod has retracted before the next pick cycle; the 39 kg vertical-lift margin covers small PCB trays comfortably.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP50X25SB with the ATE50X25SB
Size both ways before committing: the 40 mm bore pulls 500.3 N at 0.5 MPa and suits lighter clamping, while the 63 mm bore reaches 1320 N when you need more margin on the same 25 mm stroke. Remember the spring cannot hold a mid-stroke position - on air loss the rod returns to extended, so do not use it to park a load partway. If you need FA/FB flange, LB foot or CA/CB clevis mounting, or switch feedback via the -S magnet with CMSE / DMSE switches, match those options on the ATE50X25 replacement when you migrate.
Replacement checklist
- ✓ Current-production ACE → ATE50X25SB
- ✓ 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 ATP50X25SB 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) with 1.5 MPa (215 psi) proof, and 0.2 MPa is the minimum to beat the spring. For real work at 0.5 MPa plan on about 465 N, roughly a 39 kg vertical lift with a 2:1 margin. Speed range is 50-500 mm/s.
Order the ATE50X25, the current-production ISO 21287 successor: swap the P for an E and you get the same 50 mm bore, 25 mm stroke and force class in a matching short body. This unit is DIN-standard, so confirm the ISO 21287 mounting dimensions and your FA/FB, LB or CA/CB bracket fit before swapping. The male rod thread and 1/8" port carry over in the same class.
