Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X40-10SB
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ16X40-10SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 40mm 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 ACEJ12 Adjustable Compact Cylinder ACEJ16X40-10SB
The ACEJ16X40-10SB is a double acting ISO 21287 compact cylinder with a 16 mm bore and a 40 mm stroke that an external stop screw trims by up to 10 mm, giving a usable extend range of 30-40 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures where a full-length body will not fit. The hard-anodized aluminium body carries an S45C hard-chrome plated rod, a male thread on the rod end (B code), and a fixed TPU bumper at each end. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted to report end positions.

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 | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X40-10SB Is Used
Position-verified ejector
Kicking finished vials off a conveyor lane with CMSE switch confirmation of extend and retract, enabled by the fitted -S magnet on this model.
Compact test fixture clamp
Clamping small PCB assemblies inside a guarded test station where the short ISO 21287 body fits the tight envelope and the stop screw dials the stroke between 30 and 40 mm.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X40-10SB the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod will still drift if air is lost. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches confirm both end positions.
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 0.15 – 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 Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X40-10SB FAQ
The ordered stroke is 40 mm and the -10 window lets the stop screw trim the extend stroke down to 30 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome rod, threaded covers, and a fixed TPU bumper at each end that only decelerates the piston - it never locks or holds a load. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots; FA flange, LB foot and I/Y knuckles bolt straight to the ISO 21287 face.
