Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-30
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-30 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø20mm 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 ACEJ20X60-30
The ACEJ20X60-30 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. An external stop screw trims the 60 mm stroke anywhere within the ordered 30 mm window, giving a usable range of 30-60 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. A hard-anodized aluminium barrel carries the 10 mm S45C hard-chrome rod, and fixed TPU bumpers absorb end-of-stroke shock at both ends. As a rule of thumb, plan on roughly 94 N (about 9.6 kgf) of usable work at 0.5 MPa, enough to lift about 8 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi) air filtered to 40 um.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-30 Is Used
Jig clamping on CNC fixtures
The 30-60 mm adjustable stroke lets a machinist dial in clamp travel per fixture, while 157.1 N push at 0.5 MPa seats parts against CNC locators without crushing.
Carton kick-off on packaging lines
With about 9.6 kgf of usable thrust at 0.5 MPa, the cylinder nudges small cartons off a conveyor lane, and the compact body fits inside tight machine guarding.
Sample press in lab automation
The 10 mm hard-chrome rod and 30-500 mm/s speed range suit controlled sample pressing, and the short body drops into benchtop frames where longer cylinders cannot.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-30 the Right Cylinder?
For this stroke class, a 16 mm bore gives 100.5 N push at 0.5 MPa while a 25 mm bore reaches 245.4 N, so pick the ACEJ20X60-30 when your fixture needs roughly 157 N of push with on-site stroke trimming. The stop screw is a mechanical end stop for the extend stroke only; on air loss the piston can still drift, so add a separate valve solution if position must be held. FA flange or LB foot mounts bolt to the ISO 21287 face, and if you later need end-of-stroke sensing, order the -S variant with the optional magnet for CMSE / DMSE switches - this model has no magnet fitted.
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 ACEJ20X60-30 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The ordered stroke is 60 mm and the -30 code gives a 30 mm adjustment window, so the external stop screw can trim the extend stroke to any length between 30 and 60 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, a 10 mm S45C hard-chrome rod and fixed TPU bumpers at both ends; the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. This model has no magnet, so no switch can be mounted; order the -S code for the optional magnet that works with CMSE / DMSE switches. FA flange and LB foot mounts bolt straight to the ISO 21287 face.
