Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-50SB
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-50SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-50SB
The ACEJ80X80-50SB is a double acting, adjustable-stroke compact cylinder built to ISO 21287. The -50 code adds a 50 mm adjustment window: an external stop screw trims the 80 mm extend stroke down to as little as 30 mm on site, no disassembly needed. The hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and machine frames.
Because the S code is on this model, the magnet is fitted and CMSE / DMSE reed or solid-state switches can be mounted directly in the body slots for end-of-stroke signalling. The B code gives a male rod thread on the 20 mm S45C hard-chrome rod, with a 1/8" PT port. Fixed TPU bumpers absorb end-of-stroke shock at both ends, and speed spans 30-500 mm/s.

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 ACEJ80X80-50SB Is Used
Bale and carton press-down stations
With about 153 kg of usable working force at 0.5 MPa, the 80 mm bore presses cartons or bales in packaging cells where a full-length profile cylinder will not fit.
Press-fit assembly of bushings and bearings
The short ISO 21287 body mounts under low gantries, and the fitted magnet with CMSE switches confirms the 80 mm stroke is fully home before the next cycle.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-50SB the Right Cylinder?
If your load needs under 981.7 N, the 50 mm bore is the lighter pick; if you need up to 3927.0 N, step to 100 mm. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod can drift if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
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 ACEJ80X80-50SB FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -50 code sets a 50 mm adjustment window: an external stop screw shortens the 80 mm extend stroke to any setting from 30 to 80 mm. It is a mechanical end stop only, so the rod still drifts on air loss. Speed range is 30-500 mm/s.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body and an S45C hard-chrome plated 20 mm rod, saving about 50% of the mounting length of an ISO 15552 profile cylinder. Fixed TPU bumpers at both ends absorb end-of-stroke energy. Because this model carries the -S code, the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots. The B code gives a male rod thread and the port is 1/8" PT.
