About the AirTAC ASP40
Discontinued: AirTAC has replaced the ASP series with the ASE series. Every ASP code on this page is supplied as the current ASE with the same code after the prefix, for example ASP40X5 ships as ASE40X5. The specifications on this page are those of the ASE you receive.
The AirTAC ASP40 is a single-acting, spring-return compact cylinder (push type) with a 40 mm bore and a 12 mm piston rod. Compressed air extends the rod and a built-in spring retracts it when the air is released, so the rod rests retracted; only one port takes air. Catalog output with the spring force already deducted is 556.8 N push at 0.5 MPa and 808.1 N at 0.7 MPa. The spring stroke has no air behind it, so it must not carry a load.
All ASP40 versions share 1/8" air ports, an M8×1.25 rod thread and rubber bumpers at both ends. The cylinder runs on filtered air between 0.2 and 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 50 to 500 mm/s. This page lists 20 order codes with strokes from 5 to 25 mm; the catalog maximum stroke is 25 mm.

Catalog output force (Ø40 mm)
| Pressure | Push (spring deducted) |
|---|---|
| 0.5 MPa | 556.8 N |
| 0.7 MPa | 808.1 N |
AirTAC catalog values for the single-acting push type: air force on the full bore less the return-spring force. The spring stroke delivers no rated force.

Where the ASP40 Is Used
General automation
About 556.8 N at 0.5 MPa covers most pushing, lifting and indexing tasks.
Clamping fixtures
Rigid mountings hold the cylinder for clamps and presses.
Doors, gates and levers
Pivoting covers and brackets drive mechanisms that swing.
Choosing the Right ASP40 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Every code on this page is the basic version without a mounting code: the cylinder is fixed through its own mounting holes.
Finally pick the version: S adds a magnet for position sensors; B gives a male threaded rod end instead of the standard female thread.
AirTAC ASP40 FAQ
Discontinued: AirTAC has replaced the ASP series with the ASE series. Every ASP code on this page is supplied as the current ASE with the same code after the prefix, for example ASP40X5 ships as ASE40X5. The specifications on this page are those of the ASE you receive.
Air extends the rod with about 556.8 N at 0.5 MPa (catalog value, spring force deducted); the internal spring retracts it when the port is vented. The force does not depend on the stroke code.
No. The return stroke is driven only by the internal spring, and AirTAC specifies that single-acting cylinders must not be loaded on it. Use a double-acting model if both directions must do work.
1/8" ports, PT thread as standard.
Every code on this page is the basic version without a mounting code; the cylinder is fixed through its own mounting holes.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.2 to 1.0 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.
No. You can order a single ASP40. Orders are processed and handed to the carrier within 3-5 business days.
