This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE100X25SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE100X25SB 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 ASP100X25SB
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP100X25SB is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø100mm bore and 25mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE100X25SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP100X25SB
Single acting push cylinder with spring return, the AirTAC ASP100X25SB uses one air line to extend its 25 mm rod and a built-in spring to retract it. At the 100 mm bore this is the strongest size in the family: 3640.7 N of push at 0.5 MPa, already net of the spring, rising to 5211.5 N at 0.7 MPa. It needs only 0.2 MPa (28-145 psi working band) to beat the spring, so a modest supply is enough. 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 dense presses and clamping nests. Note this model is discontinued; the current-production successor is the ASE100X25.
Because the S and B codes are both present, this unit carries the optional -S magnet and a male rod thread, so CMSE or DMSE reed and solid-state switches can be fitted for end-of-stroke detection. The hard-anodized aluminium body pairs with an S45C hard-chrome rod, and fixed TPU bumpers at both ends absorb the return stroke. For sizing, treat about 0.6 of the rated push as usable work at 0.5 MPa, roughly 2184 N, which corresponds to lifting about 222 kg vertically - halve that for a 2:1 margin and you can safely raise a part of around 111 kg. Speed range is 50-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE100X25SB (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 ASP100X25SB Is Used
Bench-top crimping press
The 3640.7 N push at 0.5 MPa crimps small terminals and rivets in electronics assembly, with the 25 mm stroke sized for quick in-out tooling.
Injection mold gate clamp
Spring return guarantees the clamp opens on air loss, a fail-safe behavior molders want on short-travel gate locks near the tool.
Pallet-stacker gate latch
One air line extends the latch and the spring retracts it, so warehouse safety gates drop shut whenever power is cut.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP100X25SB with the ASE100X25SB
At 0.5 MPa this bore delivers 3640.7 N net of the spring; if your clamp or press needs less, the 80 mm ASP80X25SB gives 2316.2 N, and there is no larger bore in the family, so step to a double-acting ACE or ASE if you need more than 5211.5 N at 0.7 MPa. Remember the spring drives the rod home on air loss, so it 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 need CMSE / DMSE switching. Before swapping to the ASE100X25 replacement, confirm the ISO 21287 mounting dimensions against your drawing.
Replacement checklist
- ✓ Current-production ACE → ASE100X25SB
- ✓ 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 ASP100X25SB FAQ
Push is 3640.7 N at 0.5 MPa and 5211.5 N at 0.7 MPa, both already net of the return spring. Minimum working pressure is 0.2 MPa, the band is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed 50-500 mm/s, and the 1/4" port suits the 100 mm bore. A practical rule is to plan on about 0.6 of the 0.5 MPa figure, roughly 2184 N, which lifts about 111 kg vertically with a 2:1 margin.
AirTAC no longer produces the ASP family; the current drop-in is the ASE100X25, the same bore, stroke and force class in the ISO 21287 short body, so confirm mounting dimensions before swapping. This specific unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for position feedback; without the -S code there is no magnet.
