This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE20X25B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE20X25B 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 ATP20X25B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP20X25B is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø20mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE20X25B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP20X25B
A single acting pull cylinder with spring return, the ATP20X25B keeps its 10 mm rod extended by an internal spring and retracts it with compressed air. At 0.5 MPa the net pull is 88.1 N (135.2 N at 0.7 MPa), already after the spring is paid for, and the minimum working pressure to beat the spring is 0.2 MPa. The B code gives a male rod thread, and the port is M5x0.8, which follows the 20 mm bore. This model is discontinued; the current-production replacement is the ATE20X25, so confirm the ISO 21287 mounting dimensions before you swap.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into compact ejection and hold-down stations. As a working figure, plan on about 53 N of usable pull at 0.5 MPa, which lifts roughly 4 kg vertically with a 2:1 margin. Fixed TPU bumpers sit at both ends, and the magnet is the optional -S code only - this unit has none, so no CMSE or DMSE switch can be fitted unless you order -S.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE20X25B (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 (Ø20mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 88.1 N |
| 0.7 MPa | 135.2 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 ATP20X25B Is Used
PCB test fixture clamping release
The spring holds the hold-down pad extended over the board; 88.1 N of air pull at 0.5 MPa retracts it when the operator starts the test cycle.
Carton flap kickers on a case packer
A 25 mm stroke is enough to swing small flaps out of the way; the normally-extended rod keeps the kicker ready without air.
Sample vial ejection from a lab indexer
About 4 kg vertical lift capability at a 2:1 margin covers light vial trays, and the spring-extend design clears the station on any air failure.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP20X25B with the ATE20X25B
For light retraction jobs, the 20 mm bore gives 88.1 N at 0.5 MPa; step down to the 16 mm bore (53.3 N) for lighter loads or up to the 25 mm bore (170.9 N) when you need more margin. Remember the spring returns the rod to its extended home on air loss and will not hold a mid-stroke position. Match FA/FB flange, LB foot or CA/CB clevis brackets to your fixture, and order the -S code if you want the optional magnet for CMSE / DMSE switches. For new designs, specify the ATE20X25 instead.
Replacement checklist
- ✓ Current-production ACE → ATE20X25B
- ✓ 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 ATP20X25B FAQ
It is a single acting pull cylinder: the spring extends the rod and air retracts it. Net pull (already minus the spring) is 88.1 N at 0.5 MPa and 135.2 N at 0.7 MPa. Minimum working pressure is 0.2 MPa (28-145 psi operating range, 1.5 MPa / 215 psi proof), speed 50-500 mm/s, air filtered to 40 um, -20 to +70 C.
Order the ATE20X25, the current ISO 21287 replacement (swap the P for an E). It matches the same 20 mm bore, 25 mm stroke and force class with a short compact body, but confirm the ISO 21287 mounting dimensions against your fixture first, since the ATP follows the older DIN-standard footprint. Also note the magnet is only present if you order the -S code.
