This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE63X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE63X20S 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 ATP63X20S
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP63X20S is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø63mm bore and 20mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE63X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP63X20S
A single acting pull cylinder with spring return, the ATP63X20S keeps its 16 mm rod extended by an internal spring and uses compressed air to retract it - so a 63 mm bore delivers a net pull of 1320 N at 0.5 MPa (1903.2 N at 0.7 MPa) after the spring is subtracted. Air filtered to 40 um at 0.2-1.0 MPa (28-145 psi) drives it, with a proof rating of 1.5 MPa (215 psi), a speed range of 50-500 mm/s and a working band of -20 to +70 C. The S code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke detection.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight machine frames and fixture plates. A fixed TPU bumper at each end decelerates the rod, and the hard-anodized aluminium body with an S45C hard-chrome rod resists wear. Note that this model is discontinued: the current-production replacement is the ATE63X20, which swaps the P for an E in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on roughly 792 N (about 67 kg lifted vertically with a 2:1 margin) of real work at 0.5 MPa rather than the full 1320 N rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE63X20S (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 (Ø63mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 1320.0 N |
| 0.7 MPa | 1903.2 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 ATP63X20S Is Used
Spring-out clamp on a CNC fixture
The spring keeps the clamp jaw engaged on an aluminium workpiece; 1320 N of net pull at 0.5 MPa retracts it when air is applied, and the 20 mm stroke clears chip covers quickly.
Bottle-line reject gate retraction
On a packaging conveyor, air pulls the gate open at 50-500 mm/s while the spring snaps it back to the extended home position the moment air pressure drops.
Position-flagged lift check in a test rig
With the fitted -S magnet and a DMSE switch, the rig confirms the 16 mm rod has retracted; the spring-extend design fails safe to the extended position on air loss.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP63X20S with the ATE63X20S
Size between neighbours: the 50 mm bore pulls 775 N at 0.5 MPa and the 80 mm bore pulls 2159.1 N, so 1320 N at 0.5 MPa places this 63 mm unit in the middle of the range for clamping or retracting medium loads. If the job needs a push stroke instead, look at the ASP (single-acting push) or the double-acting ACP family, both also succeeded by ATE / ACE models. Mounting options include FA/FB flange, LB foot and CA/CB clevis, and the fitted -S magnet accepts CMSE / DMSE switches. On air loss the spring returns the rod to its extended home position and will not hold a mid-stroke point. Order the ATE63X20 as the current drop-in and verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ATE63X20S
- ✓ 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 ATP63X20S FAQ
Net of the return spring, this 63 mm bore pulls 1320 N at 0.5 MPa and 1903.2 N at 0.7 MPa. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 50-500 mm/s, with a 16 mm rod, M10x1.5 female rod thread, 1/8" PT port and a 20 mm stroke. The spring extends the rod; air retracts it, and at least 0.2 MPa is needed to overcome the spring.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded frames. A fixed TPU bumper at each end decelerates the rod, and FA/FB flange, LB foot or CA/CB clevis mounting bolts to standard faces. The ATP family is discontinued: order the ATE63X20 (P changed to E) as the current-production equivalent and confirm the ISO 21287 mounting dimensions before the swap.
