Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10S
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10S 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 ACEJ20X60-10S
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ20X60-10S pairs a 20 mm bore with a 60 mm stroke that an external stop screw trims by up to 10 mm, giving a usable range of 50-60 mm. 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 32 kgf at 1.0 MPa. The short 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 cannot.
Because the -S code is ordered, the magnet is fitted and CMSE or DMSE reed and solid-state switches can be mounted anywhere along the body slots. A practical sizing note: treat roughly 0.6 of the push force, about 94 N, as the real working figure at 0.5 MPa, which covers vertical lifts of roughly 9 kg with margin. The hard-anodized aluminium body carries an S45C hard-chrome plated rod, fixed TPU bumpers at both ends, and runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10S Is Used
Fixture clamping in CNC cells
The 157.1 N push at 0.5 MPa secures small aluminium or plastic workpieces in machining jigs, with the 50-60 mm trim matching shallow clamp pockets.
Product divert on packaging lines
A 60 mm stroke nudges cartons or blisters off a conveyor lane, and the compact body fits where an ISO 15552 profile cylinder would overhang the frame.
Position-verified test stations
With the fitted -S magnet, CMSE / DMSE switches confirm extend and retract on a 50-60 mm gated press or leak-check fixture, tuned via the stop screw.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10S the Right Cylinder?
At this bore class the 20 mm size delivers 157.1 N push at 0.5 MPa. Step down to a 16 mm bore (100.5 N) for lighter pick-and-place heads, or up to 25 mm (245.4 N) when clamping small brackets needs more reserve. The 10 mm window shortens the extend stroke only; it never extends past 60 mm, and the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod can 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 accepts CMSE / DMSE switches for end-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 0.15 – 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 ACEJ20X60-10S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa, 219.9 N push and 164.9 N pull; theoretical maximum is 32 kgf at 1.0 MPa. Speed range is 30-500 mm/s on air filtered to 40 um, with operating pressure 0.15-1.0 MPa (22-145 psi) and proof pressure 1.5 MPa (215 psi). The rod end is female M6x1.0 and the port is M5x0.8.
An external stop screw shortens the 60 mm extend stroke by up to 10 mm, so the working range is 50-60 mm; it is a mechanical end stop, not a load-holding lock. The fixed TPU bumpers at each end absorb end-of-stroke energy. Because this unit carries the optional -S magnet, CMSE / DMSE reed or solid-state switches can be clipped into the body slots for position feedback.
