Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40B

The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 300mm 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 ACEJ100X300-40B

Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy clamping and pressing stations fit inside guards and gantries that a full-length cylinder cannot enter. The -40 code adds a 40 mm adjustment window: an external stop screw trims the extend stroke anywhere between 260 and 300 mm on site.

The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with a male thread (B code), and 1/8" ports feed air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Fixed TPU bumpers absorb end-of-stroke shock at both ends, speed spans 30-500 mm/s, and the optional -S magnet enables CMSE / DMSE switches - this unit ships without it.

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.

Max (@1.0 MPa)769 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 ACEJ100X300-40B Is Used

factory

Gate drive inside a machine guard

The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, sliding a 300 mm heavy slide gate in the tight space behind a guard panel.

Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40B the Right Cylinder?

The 40 mm window suits fixtures where the final stroke is tuned after installation - trim the 300 mm extend stroke down to 260 mm by turning the stop screw. Note the adjuster is a mechanical end stop only: on air loss the piston drifts, so it never holds a load mid-stroke. FA flange or LB foot mountings bolt to the ISO 21287 face, and if position feedback is needed later, order the -S variant so CMSE / DMSE switches can be 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 ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40B FAQ

At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N and pull 5277.9 N; theoretical maximum is 800.9 kgf at 1.0 MPa. The -40 code gives a 40 mm adjustment window: an external stop screw shortens the 300 mm extend stroke to as little as 260 mm. It is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost.

The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, 20 mm hard-chrome rod, male rod thread, 1/8" ports and fixed TPU bumpers at both ends. Sensing requires the optional -S magnet: this model has no magnet, so CMSE / DMSE switches cannot be mounted unless you order the -S code.
