The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X10B is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø32mm bore and 10mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.
This AirTAC ASE32X10B is a single acting push cylinder with spring return, so air extends the rod and the built-in spring pulls it back. With a 32 mm bore it delivers 352.5 N of push force at 0.5 MPa, already net of the return spring, and needs a minimum of 0.2 MPa to overcome that spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which helps it fit into tight jigs and guarded zones. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while fixed TPU bumpers at both ends absorb end-of-stroke impact. Because this unit has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be fitted without ordering that optional magnet.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 352.5 N |
| 0.7 MPa | 513.4 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. Single-acting strokes are short (Ø12 to 10 mm, Ø16-100 to 25 mm).

ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
Use the ASE32X10B to clamp small parts in a CNC fixture. The 352.5 N push at 0.5 MPa holds components firmly during drilling, and the spring retracts the clamp automatically when air is removed.
In a packaging line, this cylinder can push a tab or flap into place on a carton. The 10 mm stroke is enough for a quick, repeatable action, and the compact body fits between conveyor rails without protruding.
Mount the ASE32X10B as a stop on a small assembly gantry. It extends to block a sliding workpiece, then retracts via spring to let it pass. The fixed TPU bumper prevents hard impact at the end of each cycle.
For a lighter duty, the 25 mm bore ASE25X10 pushes 210.1 N at 0.5 MPa, while stepping up to a 40 mm bore ASE40X10 gives 556.8 N at the same pressure. This 32 mm size suits mid-range push applications where 352.5 N is enough but a smaller bore would be marginal. The spring returns the rod to its home position on air loss, but it does not hold a load at an intermediate stroke position. With the B code, the rod has a male thread, and the port is 1/8" PT. If you need sensor feedback, order the -S version to get the optional magnet for CMSE or DMSE switches.
Quick checklist
The ASE32X10B is single acting push with spring return. It delivers 352.5 N of push force at 0.5 MPa and 513.4 N at 0.7 MPa, both net of the return spring. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (145 psi).
It follows the ISO 21287 compact standard, so its body is about 50% shorter than an ISO 15552 profile cylinder. This makes it easier to fit in tight spaces. It also has fixed TPU bumpers at both ends to absorb impact, and the optional -S magnet is needed if you want to use CMSE or DMSE sensors.
