This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE100X20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE100X20 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 ATP100X20
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP100X20 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 ATE100X20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP100X20
A single acting pull cylinder with spring return, the ATP100X20 keeps its 25 mm rod extended by an internal spring and retracts it with air, delivering 3395.3 N of pull at 0.5 MPa (4867.9 N at 0.7 MPa), both figures already net of the spring. The 100 mm bore needs at least 0.2 MPa to overcome the spring, and the short ISO 21287-style body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into dense press fixtures and gantries. Note this model is discontinued; the current-production replacement is the ATE100X20.
For sizing, plan on about 2037 N (roughly 207 kgf) of real work at 0.5 MPa rather than the full rating, which means it lifts about 173 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a fixed TPU bumper at both ends, the S45C rod ends in a female M16x1.5 thread, and the 1/4" port suits bores of this size. FA/FB flange, LB foot and CA/CB clevis brackets bolt to the standard face. If you need position feedback, the optional -S magnet enables CMSE / DMSE switches; without -S there is no magnet fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE100X20 (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 ATP100X20 Is Used
Spring-extended clamping of aluminium die-cast housings
The spring holds 3395.3 N of pull-side grip on the fixture while air retracts the rod for loading; on air loss the housing stays clamped automatically.
Return-home ejection on a 20 mm stamping press
The 20 mm stroke is enough to strip a small formed part off the punch, and the spring snaps the tooling back to its extended home between cycles at 50-500 mm/s.
Fail-safe lid release on a food packaging machine
Washdown-safe spring extension keeps the sealing head retracted-free; air at 0.2-1.0 MPa (28-145 psi) pulls the head in only when the guard logic allows it.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP100X20 with the ATE100X20
Compare forces at 0.5 MPa: the 80 mm bore pulls 2159.1 N while this 100 mm bore pulls 3395.3 N, so step down if your clamp load is under about 2000 N. 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 you need one. Match FA/FB flange, LB foot or CA/CB clevis mounting to your fixture, order -S only if CMSE / DMSE sensing is required, and confirm ISO 21287 mounting dimensions on the ATE100X20 before swapping from this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ATE100X20
- ✓ 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 ATP100X20 FAQ
At 0.5 MPa the rod pulls 3395.3 N; at 0.7 MPa it pulls 4867.9 N. Both figures are net of the return spring, so no deduction is needed. Minimum working pressure is 0.2 MPa (28 psi) to beat the spring, the operating range is 0.2-1.0 MPa (28-145 psi), proof pressure is 1.5 MPa (215 psi), speed is 50-500 mm/s, and the rod is a 25 mm rod with female M16x1.5 thread on a 1/4" PT port.
Order the ATE100X20, the current-production ISO 21287 successor: swap the P for an E and you get the same 100 mm bore, 20 mm stroke and force class with a matching short body and mounting family. Because the ATP was built to a DIN-standard compact pattern, confirm the ISO 21287 mounting dimensions against your fixture before swapping.
