This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE20X15SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE20X15SB 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 ASP20X15SB
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP20X15SB 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 ASE20X15SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP20X15SB
A single acting push cylinder with spring return, the ASP20X15SB extends its 10 mm rod with compressed air and lets the internal spring retract it, so only one air line is needed. At the 20 mm bore it delivers 127.4 N of push at 0.5 MPa (190.2 N at 0.7 MPa), already net of the spring, and it starts moving from just 0.2 MPa. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body will not fit. The male rod thread (B code) takes standard I/Y knuckles directly. For sizing, treat roughly 76 N as the usable working force at 0.5 MPa, which lifts about 6 kg vertically with a 2:1 margin. Note that this ASP series is discontinued; the current-production replacement is ASE20X15, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE20X15SB (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.

Where the Airtac ASP Single Acting Guided Compact Cylinder ASP20X15SB Is Used
Bottle capping press
A 127.4 N push at 0.5 MPa seats snap caps on 50 ml cosmetic bottles; the 15 mm stroke matches the cap engagement depth exactly.
Presence-check ejector on PCB test bench
With the -S magnet fitted, a DMSE switch confirms the rod is retracted before the test fixture cycles, and the spring returns it on air loss.
Small-carton flap tucker
The male rod thread bolts an I knuckle that folds carton flaps on a semi-auto packing line, needing only one solenoid valve and one air line.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP20X15SB with the ASE20X15SB
Size between bores: the 16 mm ASP gives 78.4 N at 0.5 MPa, while the 25 mm bore reaches 210.1 N, so pick the 20 mm when your load sits between roughly 80 and 210 N. Because the spring retracts the rod on air loss, the cylinder always parks retracted and cannot hold a mid-stroke position. Mount with FA/FB flange, LB foot or CA/CB clevis brackets, and order the -S code if you need CMSE / DMSE switch sensing. For new projects, specify the ASE20X15 instead, as this model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ASE20X15SB
- ✓ 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 ASP20X15SB FAQ
Push force is 127.4 N at 0.5 MPa and 190.2 N at 0.7 MPa, both already net of the return spring. It needs at least 0.2 MPa to overcome the spring, runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure, moves at 50-500 mm/s, and works from -20 to +70 C. There is no pull force because the cylinder is single acting push with spring return.
The hard-anodized aluminium body follows the short ISO 21287-class format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, and a fixed TPU bumper sits at both ends to soften the stop. The port is M5x0.8, the rod end is male thread, and the model is discontinued with ASE20X15 as the current drop-in replacement.
