The AirTAC Airtac ACQ Ultra Thin Air Cylinder ACQ100X175S is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø100mm bore and 175mm stroke, PT3/8 air ports and a C-clip / riveted short body that saves mounting depth. Magnetic-switch slots around the body accept position sensors.
The AirTAC ACQ100X175S is a double-acting, single-rod JIS compact cylinder engineered for substantial actuation tasks, providing 3927 N of push force and 3524.8 N of pull force at 0.5 MPa. Because this 175 mm stroke exceeds the 100 mm standard maximum for this bore size, it is configured as a made-to-order long-stroke variant within the Ø32-100 range, extending up to 300 mm.
This unit features a built-in piston magnet (-S) for position sensing via AirTAC reed or electronic switches fitted into the body grooves. Deceleration relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to manage the impact safely.

Drives large robotic welding guns on automotive assembly lines, utilizing the 3927 N push at 0.5 MPa to firmly hold heavy steel panels during the spot-welding process.
Executes 175 mm strokes to index loaded pallets between heavy-duty roller conveyor sections, relying on the long-stroke body to clear adjacent transport lanes.
Provides the extended reach and 5497.8 N push at 0.7 MPa needed to positively eject large molded plastic bins from deep injection tooling cavities.
When sizing your system, consider the force scaling: stepping down to a 63 mm bore yields 1558.6 N of push at 0.5 MPa, while this 100 mm bore provides 3927 N, and moving up to the 125 mm big-bore tier increases that output to 6135.9 N. Ensure your ordering essentials match the 100 mm bore, 175 mm non-standard stroke, PT3/8 port, female M20x2.5 rod end, and the required -S sensor magnet.
Remember that a standard compact body does not maintain its position if air pressure drops or the directional valve is centered; the rod will drift, and the fixed bumper only softens the end-of-stroke stop. For fail-safe load holding, incorporate an external rod lock or a pilot-operated check valve into your circuit.
Quick checklist
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.8 N pull at 0.5 MPa, 5497.8 N push at 0.7 MPa, and a maximum push of 801 kgf at 1.0 MPa. It uses a PT3/8 port, a 32 mm piston rod, and operates at speeds of 30-500 mm/s.
No, the ACQ100X175S uses a fixed NBR elastomer bumper at each end to absorb end-stop impact, which is not field-adjustable. For high-speed or high-energy loads, you should add an external shock absorber or slow the approach velocity.
