Airtac ACQ Ultra Thin Air Cylinder ACQ25X35B
The AirTAC Airtac ACQ Ultra Thin Air Cylinder ACQ25X35B is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø25mm bore and 35mm stroke, M5×0.8 air ports and a C-clip / riveted short body that saves mounting depth. Magnetic-switch slots around the body accept position sensors.

About the Airtac ACQ Ultra Thin Air Cylinder ACQ25X35B
The AirTAC ACQ25X35B is a double-acting, single-rod JIS compact cylinder engineered to deliver 245.4 N of push force and 188.9 N of pull force at 0.5 MPa. Its short C-clip and riveted piston-to-rod assembly significantly reduce overall axial length compared to standard round-body units, saving valuable mounting depth in tight machinery layouts.
This specific configuration features a male-thread piston rod end (M10x1.25) for direct mechanical coupling to your load. The 12 mm piston rod moves within a hard-anodized aluminum bore, while a fixed TPU elastomer bumper at each end absorbs end-stop shock. The body retains integrated sensor grooves, though this particular unit ships without the internal magnet.

Where the Airtac ACQ Ultra Thin Air Cylinder ACQ25X35B Is Used
CNC Fixture Clamping
Provides 245.4 N of extension force to secure aluminum workpieces against a V-block before a machining center starts its cutting cycle.
Package Diverting Arm
Uses the 35 mm stroke to push small corrugated cartons off a main packaging belt onto a secondary gravity roller lane.
Lab Sample Ejection
Ejects filled vials from a centrifuge carousel using its male M10x1.25 rod end, relying on the fixed TPU bumper to prevent glass breakage.
Is the Airtac ACQ Ultra Thin Air Cylinder ACQ25X35B the Right Cylinder?
When sizing this 25 mm bore model, consider stepping down to the 20 mm bore for lighter tasks (157.1 N push at 0.5 MPa) or up to the 32 mm bore for heavier demands (402.1 N push at 0.5 MPa). Remember that a standard ACQ body does not hold its position if air pressure drops or the valve is centered; the rod will drift. For fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve.
To finalize your RFQ for this unit, confirm the 25 mm bore, 35 mm stroke, M5x0.8 port, male M10x1.25 rod thread, and the absence of a sensor magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQ Ultra Thin Air Cylinder ACQ25X35B FAQ
At 0.5 MPa, the push force is 245.4 N and the pull force is 188.9 N. At 0.7 MPa, the push force is 343.6 N. The maximum push force is 50 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
No, it uses a fixed TPU elastomer bumper at each end to decelerate the piston. It is not a field-adjustable air cushion, so for high-speed or high-energy cycles, you should slow the approach or add an external shock absorber.
