Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X20B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X20B is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 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.

About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X20B
This AirTAC ASE16X20B is a single acting push cylinder with spring return, meaning air extends the rod and a built-in spring pulls it back when pressure drops. It delivers 78.4 N of push force at 0.5 MPa, already net of the return spring, so you can plan around that figure directly.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which helps it fit into tight jigs and guarded areas. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a safe vertical lift, plan for about 4.8 kg (roughly 60% of the 78.4 N rating) to keep a 2:1 margin over the theoretical maximum.

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.
Theoretical Output Force (Ø16mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 78.4 N |
| 0.7 MPa | 118.6 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).

Where the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X20B Is Used
Compact Jig Clamping
Use the 20 mm stroke to clamp small parts in a tight CNC fixture where a full-length cylinder would not fit, relying on the spring return to release the part automatically.
Light Label Applicator
Drive a label tamp head in a packaging line, where the 78.4 N push at 0.5 MPa is enough to press labels onto cartons and the spring retracts quickly for the next cycle.
Guard Door Interlock
Actuate a small safety interlock pin on a machine guard, using the spring return to withdraw the pin when air is removed, ensuring the guard stays closed without power.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X20B the Right Cylinder?
When sizing, compare this 16 mm bore against the 12 mm bore, which pushes 40.0 N at 0.5 MPa, or the 20 mm bore at 127.4 N. If you need a powered return stroke, consider the ACE double-acting version instead, since the ASE spring only retracts and does not hold a mid-stroke position. The male rod thread (B code) suits direct coupling to a load, and the M5x0.8 port is standard for this bore. Since this unit has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted; order the -S option if you need position sensing.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Single-acting: do not force the rod against the spring.
- check Installation by qualified personnel per AirTAC docs.
Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X20B FAQ
The ASE16X20B delivers 78.4 N push at 0.5 MPa and 118.6 N push at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi). Operating temperature range is -20 to +70 C, with a speed range of 50-500 mm/s.
Yes, it is an ISO 21287 compact cylinder with a body about 50% shorter than an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, not an adjustable cushion. The hard-anodized aluminium body and S45C hard-chrome rod provide durability in tight spaces.
