This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE100X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE100X20B 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 ATP100X20B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP100X20B is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø100mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE100X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP100X20B
A single acting pull cylinder with spring return, the ATP100X20B uses a 100 mm bore and a 20 mm stroke to deliver 3395.3 N of pull at 0.5 MPa (4867.9 N at 0.7 MPa), both figures already net of the return spring. The spring holds the rod extended at rest, so on air loss the rod fails to its extended home position rather than holding a mid-stroke point. Air only needs 0.2 MPa to overcome the spring and retract the rod. This model is discontinued; the current-production replacement is the ATE100X20, which swaps the P for an E in the same bore, stroke and force class.
The short ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this 100 mm bore still fits tight press fixtures and guarded gantries. The hard-anodized aluminium body carries a 25 mm S45C hard-chrome rod, a fixed TPU bumper at both ends, and a male rod thread (the B code) with a 1/4" port. Plan on roughly 2037 N of real work at 0.5 MPa, and note the rod lifts about 173 kg vertically with a 2:1 margin. Confirm the ISO 21287 mounting dimensions before swapping to the ATE100X20.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE100X20B (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 (Ø100mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 3395.3 N |
| 0.7 MPa | 4867.9 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 ATP100X20B Is Used
Scrap chute gate retraction
The 3395.3 N pull at 0.5 MPa drags a heavy slide gate open against chute friction, and the spring slams it closed to extended the moment air is lost.
Die cart latch release
A 20 mm stroke is enough to withdraw a spring-loaded die cart latch pin; the male rod thread takes a knuckle for a quick-release link.
Pallet conveyor stopper drop
Air retracts the stopper blade out of the pallet path at up to 500 mm/s, while the spring return keeps it raised (fail-safe) whenever the line loses pressure.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP100X20B with the ATE100X20B
Size down to the ATP80X20B when 2159.1 N of pull at 0.5 MPa is enough, or stay at this 100 mm bore when your clamp or strip tool needs the full 3395.3 N. Because the spring returns the rod to extended on air loss, this bore suits fail-safe retract jobs, not mid-stroke holding. The male rod thread (B code) bolts directly to I/Y rod knuckles; FA/FB flange, LB foot and CA/CB clevis brackets match the ISO 21287 face. No magnet is fitted on this code, so no CMSE or DMSE switch can be read; order the -S variant if position sensing is needed. For new builds, specify the ATE100X20 instead.
Replacement checklist
- ✓ Current-production ACE → ATE100X20B
- ✓ 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 ATP100X20B FAQ
At 0.5 MPa it pulls 3395.3 N, and at 0.7 MPa it pulls 4867.9 N, both already net of the return spring. Minimum working pressure is 0.2 MPa (28 psi) to beat the spring, with a 0.2-1.0 MPa (28-145 psi) operating band and 1.5 MPa (215 psi) proof pressure. Speed range is 50-500 mm/s. As a rule of thumb, budget about 2037 N for real work at 0.5 MPa, which is roughly a 173 kg vertical lift with a 2:1 margin.
It is a compact ISO 21287-style body in hard-anodized aluminium with a 25 mm S45C hard-chrome rod, a male rod thread (B code), a 1/4" PT port and a fixed TPU bumper at each end that only decelerates the stroke ends. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. No magnet is fitted on this code, so CMSE or DMSE switches require the -S variant. The model is discontinued; the ATE100X20 is the current drop-in, so confirm the ISO 21287 mounting dimensions before swapping.
