This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE63X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE63X20B 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 ATP63X20B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP63X20B 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 ATE63X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP63X20B
A single acting pull cylinder with spring return, the ATP63X20B keeps its 16 mm rod extended by spring and retracts it with air, delivering 1320 N of pull at 0.5 MPa (1903.2 N at 0.7 MPa), both figures already net of the return spring. Air filtered to 40 um at 0.2-1.0 MPa (28-145 psi) drives it, proof pressure is 1.5 MPa (215 psi), and speed runs 50-500 mm/s. The male rod thread (B code) and PT port thread come as coded, and a fixed TPU bumper sits at both ends.
The hard-anodized aluminium body is a short ISO 21287 style build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping nests and guarded assemblies. At 0.5 MPa the net pull equals roughly 134 kgf, so halving for a 2:1 margin lets it lift about 67 kg vertically - size the part weight against that figure. This model is discontinued; the current drop-in is the ATE63X20, so confirm ISO 21287 mounting dimensions before swapping. The optional -S magnet enables CMSE / DMSE switches; this code has no magnet fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE63X20B (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 ATP63X20B Is Used
Spring-extended clamp nest
On a machining fixture the spring holds the clamp closed with 1320 N net pull at 0.5 MPa; air retracts it only when the PLC commands the unload step, so a power cut leaves the part clamped.
Pallet lift-and-lower link
With about 67 kg of vertical lift capacity at a 2:1 margin, the 20 mm stroke lowers small pallets or fixtures onto locating pins and the spring lifts them back home when air is lost.
Carton hold-down on a case packer
The short body saves roughly half the mounting length of an ISO 15552 profile cylinder, letting the hold-down arm sit inside a tight guarding envelope while the male rod thread picks up a knuckle directly.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP63X20B with the ATE63X20B
At 1320 N net pull at 0.5 MPa this 63 mm bore sits between the 50 mm (775 N) and 80 mm (2159.1 N) single acting pull sizes - step down when the load is light, up when it is heavy. The spring returns the rod to its extended home on air loss and will not hold a mid-stroke position, so add an external stop if the cycle needs one. FA/FB flange, LB foot and CA/CB clevis brackets bolt to the same face, and ordering the -S code adds the magnet for CMSE / DMSE switches. For new builds, specify the ATE63X20 instead - this ATP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ATE63X20B
- ✓ 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 ATP63X20B FAQ
It is a single acting pull cylinder: the spring extends the rod and air retracts it. Net pull is 1320 N at 0.5 MPa and 1903.2 N at 0.7 MPa, both already after the spring is subtracted. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, and the minimum 0.2 MPa is what it takes to beat the spring. Speed range is 50-500 mm/s with a fixed TPU bumper at each end.
Order the ATE63X20, the current-production successor: swap the P for an E and you get the same 63 mm bore, 20 mm stroke and force class in the short ISO 21287 body. Confirm the ISO 21287 mounting dimensions against your fixture before the swap, since the ATP follows the older DIN-standard footprint. If you need position sensing on the replacement, order the -S magnet code so CMSE / DMSE switches can be fitted.
