Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-40S
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-40S is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 160mm stroke, 1/8" 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 ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-40S
The ACEJ80X160-40S is a double acting, adjustable-stroke compact cylinder built to ISO 21287: an 80 mm bore with a 160 mm stroke, a 20 mm hard-chrome S45C rod and 1/8" ports. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those figures rise to 3518.6 N and 3298.7 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The -40 code adds an external stop screw that trims the extend stroke anywhere in a 40 mm window, so the working range is 120-160 mm, set on site with a spanner rather than a new order.
The hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, which is why this bore class fits inside press guards, weld fixtures and gantry frames that full-length bodies cannot enter. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the fitted -S magnet lets CMSE or DMSE switches 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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 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 ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-40S Is Used
Ejector on stamping and press lines
Short ISO 21287 body slides under press bolsters where an ISO 15552 profile cylinder would not fit, pushing finished blanks off the die at up to 500 mm/s.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-40S the Right Cylinder?
If your load sits under 981.7 N, the 50 mm bore does the same job in less space; if you need over 3518.6 N, step up to the 100 mm bore. Remember the stop screw only shortens the extend stroke within the 40 mm window and never holds a load on air loss. FA flange, LB foot and FTC brackets bolt to the ISO 21287 face, and this unit already carries the -S magnet for CMSE / DMSE switching.
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 ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-40S FAQ
For sizing, plan on about 60% of the push figure, roughly 1500 N of usable work, and expect around 128 kg of vertical lift at 0.5 MPa before any safety margin. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um.
The -40 code means an external stop screw limits the extend stroke anywhere within a 40 mm window, giving a usable range of 120-160 mm; it shortens the stroke only and acts as an end stop, not a mid-stroke lock, so the rod still drifts if air is lost. A fixed TPU bumper at both ends absorbs end-of-stroke impact. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be mounted in the body slots for end-position sensing. FA flange and LB foot mounts bolt straight to the ISO 21287 face.
