About the Airtac ACE Compact Cylinder ACE100X275SB

This AirTAC ACE100X275SB is a double acting ISO 21287 compact cylinder, delivering a powerful 3927 N push force at 0.5 MPa. Its short, hard-anodized aluminum body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight automation cells. The included -S magnet enables the use of CMSE or DMSE switches for precise position sensing.

With a 275 mm stroke and a 20 mm hard-chrome plated rod, this unit offers a practical working load of about 240 kg when you apply a 0.6 safety factor to its theoretical force. The fixed TPU bumpers at both ends absorb impact energy, while the 1/4" port ensures good flow for high-speed cycling up to 500 mm/s.

Where the Airtac ACE Compact Cylinder ACE100X275SB Is Used

precision_manufacturing

Press Fit Station

Use the 3927 N push force to press bushings or bearings into housings on an assembly line, with the compact body fitting under a guard.

vertical_align_bottom

Vertical Lift Gate

With a safe lift capacity of about 240 kg, this cylinder can raise a heavy safety gate or a part separator in a packaging machine.

settings

Clamping Fixture

Mount this cylinder on a jig to clamp large workpieces during CNC machining, using the 3769.9 N pull force to hold parts securely.

Is the Airtac ACE Compact Cylinder ACE100X275SB the Right Cylinder?

For lighter duty in a smaller envelope, consider the ACE80X275 with 2513 N push, or step up to the ACE125X275 for a substantial 6136 N of force at the same pressure. This 100 mm bore model hits a sweet spot for medium-to-heavy pushing tasks. Since this version includes the -S magnet, you can directly mount CMSE or DMSE sensors for piston position feedback, which is essential for automated sequencing.

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 ACE Compact Cylinder ACE100X275SB FAQ

At 0.5 MPa, the push force is 3927 N and the pull force is 3769.9 N. At 0.7 MPa, push increases to 5497.8 N and pull to 5277.9 N. The theoretical maximum force is 800.9 kgf at 1.0 MPa.

Yes, this model includes the optional -S magnet, allowing you to mount CMSE or DMSE switches for position detection. It is an ISO 21287 compact cylinder with a hard-anodized aluminum body, which is about 50% shorter than an ISO 15552 profile cylinder. It features fixed TPU bumpers for end-of-stroke deceleration.
