This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE20X15B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE20X15B 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 ASP20X15B
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP20X15B is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø20mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE20X15B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP20X15B
A single acting push cylinder with spring return, the discontinued ASP20X15B extends its 10 mm rod with air and retracts it by spring, so one air line is all the plumbing a 15 mm stroke needs. At 0.5 MPa the net push is 127.4 N (190.2 N at 0.7 MPa, already net of the spring), and it needs just 0.2 MPa to beat the spring. The male rod thread (B code) bolts straight to I/Y knuckles on the ISO 21287 face.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding. For planning, count on roughly 76 N of real work at 0.5 MPa, enough to lift about 6 kg vertically with a 2:1 margin. This model is discontinued: the current-production drop-in is the ASE20X15, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE20X15B (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 | Push force (spring return) |
|---|---|
| 0.5 MPa | 127.4 N |
| 0.7 MPa | 190.2 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.
Model Code: Airtac ASP Single Acting Guided Compact Cylinder ASP20X15B
| ASP | DIN compact cylinder (single-acting push, spring-return, discontinued). |
|---|---|
| 20 | Bore size in mm. |
| ×15 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (adjustable stroke).
Where the Airtac ASP Single Acting Guided Compact Cylinder ASP20X15B Is Used
Bench-top press jig
The 127.4 N net push at 0.5 MPa seats small terminals or dowels in electronics assembly, and the 15 mm stroke keeps the jig footprint minimal.
Reject gate on a filling line
One air line extends the gate to tip off-spec bottles; the spring retracts it the moment pressure drops, a fail-safe default for food and beverage lines.
Sample elevator in lab automation
With about 6 kg of vertical lift capacity at a 2:1 margin, the cylinder raises microplate carriers in compact analyzer modules where length is scarce.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP20X15B with the ASE20X15B
Size against neighbours: the 16 mm bore gives 78.4 N at 0.5 MPa while the 25 mm bore reaches 210.1 N, so the 20 mm at 127.4 N sits in the middle for light clamping and ejection. Remember the spring drives the rod home on air loss, so it will not hold a mid-stroke position. If you need position sensing, order the -S code to enable CMSE / DMSE switches; this plain code has no magnet. For new builds, specify the ASE20X15 instead, as the ASP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ASE20X15B
- ✓ 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 ASP20X15B FAQ
Net push (spring already subtracted) is 127.4 N at 0.5 MPa and 190.2 N at 0.7 MPa. Bore 20 mm, stroke 15 mm, rod 10 mm with male thread, M5x0.8 port, operating pressure 0.2-1.0 MPa (28-145 psi), proof 1.5 MPa (215 psi), speed 50-500 mm/s, temperature -20 to +70 C, fixed TPU bumper both ends. The model is discontinued; the ASE20X15 is the current replacement.
The ISO 21287 short body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot and CA/CB clevis brackets bolt to the same face. Switches are possible only on the -S version, which carries the optional magnet for CMSE / DMSE sensors; this non-S code has no magnet, so confirm the -S code at order time.
