About the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ25X35B
The B01-ACQ25X35B is an AirTAC application-dedicated (customer-specified) variant of the standard ACQ25X35B, sharing the exact same physical specifications. It is a double-acting JIS compact cylinder that provides a push force of 245.4 N and a pull force of 188.9 N at 0.5 MPa. The short C-clip and riveted body design significantly reduces axial footprint compared to traditional round-body units, making it ideal for tight machine envelopes.
This specific model features a male-threaded piston rod end (M10x1.25) for direct load coupling, a 12 mm rod diameter, and an M5x0.8 port. End-of-stroke deceleration is handled by a fixed TPU elastomer bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles. The body includes magnetic-switch grooves, though this SKU ships without the internal magnet.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ25X35B Is Used
PCB Depaneling Router
Provides the 245.4 N extension force needed to actuate the cutting head feed on an electronic board depaneling machine, where the male M10x1.25 rod threads directly into the tool carriage.
Carton Flap Folder
Drives the mechanical flap-folding arm on a packaging line, utilizing the 35 mm stroke to tuck corrugated box flaps prior to tape sealing within a constrained frame.
Stamping Pin Alignment
Positions and holds small metal brackets in a light-duty stamping press, relying on the fixed TPU bumper to soften the 30-500 mm/s travel impact at the end of the stroke.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ25X35B the Right Cylinder?
When sizing this 25 mm bore actuator, stepping down to a 20 mm bore reduces the 0.5 MPa push force to 157.1 N, while stepping up to a 32 mm bore increases it to 402.1 N. Ensure your ordering essentials match this configuration: 25 mm bore, 35 mm stroke, M5x0.8 port, male M10x1.25 rod thread, and no sensor magnet. Note that a plain compact cylinder like this does not hold its position if air pressure is lost; the rod will drift and the fixed bumper only decelerates it near the stroke end. For a fail-safe hold, an external rod lock or pilot-operated check valve is required.
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 B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ25X35B FAQ
This 25 mm bore cylinder delivers a push force of 245.4 N and a pull force of 188.9 N at 0.5 MPa. At 0.7 MPa, the push force is 343.6 N, with a maximum push capacity of 50 kgf at 1.0 MPa. The maximum standard stroke available for this bore size is 100 mm.
The B01- prefix indicates this is an AirTAC application-dedicated (customer-specified) variant of the ACQ25X35B, meaning it is mechanically identical to the base model. It does not have an adjustable air cushion; instead, it uses a fixed TPU elastomer bumper at each end to absorb the stop impact. For high-speed applications, you should slow the approach or add an external shock absorber.
