This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE100X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE100X20B 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 ASP Single Acting Guided Compact Cylinder ASP100X20B
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP100X20B is a single acting, push (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 ASE100X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP100X20B
A single acting push cylinder with spring return, the ASP100X20B extends its 25 mm rod with compressed air and lets the internal spring pull it back home, so one air line is all the plumbing it needs. At the big 100 mm bore this model delivers 3640.7 N of push at 0.5 MPa and 5211.5 N at 0.7 MPa, both figures already net of the spring, and it starts moving from just 0.2 MPa. The B code gives a male rod thread and the port is 1/4".
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is how a 3640 N clamp fits inside a tight welding fixture or press guard. In practice, plan on about 2184 N of usable work at 0.5 MPa, which is roughly 223 kg of vertical load; with a 2:1 margin it lifts about 185 kg vertically. Note this unit is discontinued: the current-production drop-in is the ASE100X20, so confirm the ISO 21287 mounting dimensions before swapping. A fixed TPU bumper sits at both ends, and the optional -S magnet enables CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE100X20B (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 | Push force (spring return) |
|---|---|
| 0.5 MPa | 3640.7 N |
| 0.7 MPa | 5211.5 N |
Single-acting push: air extends the rod; the return spring retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ASP Single Acting Guided Compact Cylinder ASP100X20B Is Used
Press-shop hold-down clamp
Clamps a 180 kg steel stamping against a jig with about 3640 N of push at 0.5 MPa; the spring retracts automatically when the air drops, freeing the part for unloading.
Palletizer part ejector
The 20 mm stroke kicks boxes or offcuts off a conveyor stop plate at up to 500 mm/s, and the short body slots into the gantry frame where a full-length cylinder cannot.
CNC fixture swing-away latch
Locks a machining-fixture latch plate with one solenoid valve; the male rod thread (B code) takes a rod knuckle directly, and the 1/4" port keeps plumbing simple.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP100X20B with the ASE100X20B
Size by force: if 3640.7 N at 0.5 MPa is more than your clamp needs, the 80 mm bore gives 2316.2 N at the same pressure; if you need more, this is the largest bore in the range. The 20 mm stroke suits short-throw clamping and eject jobs, and speeds run 50-500 mm/s. Remember the spring returns the rod on air loss, so it will not hold a mid-stroke position under load. Choose FA/FB flange, LB foot or CA/CB clevis to match your fixture, and add the -S code only if you want CMSE / DMSE switch sensing. For new builds, order the ASE100X20 instead and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ASE100X20B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ASP Single Acting Guided Compact Cylinder ASP100X20B FAQ
It is a single acting push, spring-return cylinder: air extends the rod and the spring retracts it. Push force is 3640.7 N at 0.5 MPa and 5211.5 N at 0.7 MPa, both already net of the return spring. Operating pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, air filtered to 40 um, temperature -20 to +70 C, speed 50-500 mm/s, bore 100 mm, stroke 20 mm, rod 25 mm, 1/4" port and male rod thread. On air loss the spring sends the rod home; it does not hold a mid-stroke position.
Yes, the ASP family is out of production. The current drop-in is the ASE100X20 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 short-body format - confirm the mounting dimensions before swapping. On this ASP unit the magnet is not fitted; only models ordered with the optional -S code accept CMSE / DMSE reed or solid-state switches. Both cylinders use a fixed TPU bumper at each end and a hard-anodized aluminium body with an S45C hard-chrome rod.
