This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ASE40X10B, the same code under the new prefix. 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 ASP40X10B
The AirTAC ASP Single Acting Guided Compact Cylinder ASP40X10B is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø40mm bore and 10mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE40X10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP40X10B
A single acting push cylinder with spring return, the ASP40X10B extends its 12 mm rod with air and retracts on the built-in spring, so only one air line is needed. This discontinued 40 mm bore model delivers 556.8 N of push at 0.5 MPa (808.1 N at 0.7 MPa), already net of the spring. Its short ISO 21287-class body saves roughly 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) suits external rod knuckles, and the fixed TPU bumper at both ends simply decelerates the rod. Replacement is the current-production ASE40X10 - confirm the ISO 21287 mounting dimensions before swapping, since this model follows the DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE40X10B (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 (Ø40mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 556.8 N |
| 0.7 MPa | 808.1 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.

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 (double rod, adjustable stroke).
Where the Airtac ASP Single Acting Guided Compact Cylinder ASP40X10B Is Used
Injection mold part ejection
The 556.8 N push at 0.5 MPa ejects cooled plastic parts from shallow mold cavities, and the spring retracts the rod the moment air is vented.
Bench-top clamping fixture
A 10 mm stroke clamps small aluminium brackets in a machining jig; the short body fits where an ISO 15552 profile cylinder would overhang the fixture.
Carton hold-down on a packing line
Spring return keeps the pad lifted between cycles, then air pressure presses carton flaps down at roughly 28 kg vertical equivalent.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP40X10B with the ASE40X10B
At 40 mm bore you sit mid-range: the 32 mm size gives 352.5 N at 0.5 MPa if your load is lighter, while the 50 mm bore pushes 875.5 N when you need more clamping force at the same 0.5 MPa supply. Remember the spring returns the rod to its retracted home on air loss - it will not hold a mid-stroke position under load. If you need position sensing, order the -S variant to enable CMSE / DMSE switches; this plain ASP40X10B has no magnet fitted. Mounting brackets FA/FB flange, LB foot and CA/CB clevis bolt to the standard face. For new projects, specify the ASE40X10 instead, as this model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ASE40X10B
- ✓ 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 ASP40X10B FAQ
Push is 556.8 N at 0.5 MPa and 808.1 N at 0.7 MPa, both already net of the return spring. Minimum working pressure is 0.2 MPa (28 psi) to overcome the spring; the range is 0.2-1.0 MPa (28-145 psi) with proof pressure of 1.5 MPa (215 psi). Speed runs 50-500 mm/s and the fluid is air filtered to 40 um.
The ASP family is no longer in production. The current direct is the ASE40X10, which keeps the same 40 mm bore, 10 mm stroke and force class in the ISO 21287 short-body format. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since this model follows the DIN-standard footprint. Also note the magnet is optional: only the -S code accepts CMSE / DMSE switches.
