Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-20SB
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ16X60-20SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 60mm 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 ACEJ16X60-20SB
The ACEJ16X60-20SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. An external stop screw trims the 60 mm stroke by up to 20 mm on site, giving a usable extend range of 40-60 mm without changing the cylinder. The male rod thread (B code) bolts straight into knuckle fittings.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke shock. Because this model carries the optional -S magnet, CMSE or DMSE reed and solid-state switches can be clamped onto the body for end-of-stroke signalling. As a rule of thumb, plan on about 60 N (roughly 6 kg of vertical lift) of real work at 0.5 MPa rather than the full 100.5 N rating.

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 ACEJ16X60-20SB Is Used
Pick-and-place with position feedback
With the -S magnet fitted, CMSE or DMSE switches report rod position on a compact electronics-assembly gantry where the short body must fit between guide rails.
Light clamping on test benches
Holds small PCB or sensor housings against a fixture with about 60 N of usable clamping force at 0.5 MPa, trimmed to exactly the stroke the jig needs.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-20SB the Right Cylinder?
The 60 mm stroke is well inside the 75 mm maximum standard stroke for this bore, so no made-to-order build is needed. The stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the rod still drifts, so do not rely on it to hold a load. FA flange or LB foot mounts and I/Y rod knuckles bolt to the standard ISO 21287 face.
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 ACEJ16X60-20SB FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, with a 16 mm bore, 60 mm stroke, 8 mm male-thread rod and M5x0.8 ports.
An external stop screw shortens the extend stroke by up to 20 mm, so the 60 mm stroke can be set anywhere from 40 to 60 mm on site; it is an end stop only and never holds a load on air loss. The hard-anodized aluminium body carries the optional -S magnet fitted on this model, so CMSE / DMSE switches can be added. FA flange, LB foot and I/Y knuckles mount to the ISO 21287 face, and the short body saves about 50% of the length of an ISO 15552 profile cylinder.
