Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA25X30SB
The AirTAC Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA25X30SB is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 30mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.

About the Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA25X30SB
The B52-SDA25X30SB is AirTAC's copper-free (copper-prohibited) build of the SDA25X30SB compact cylinder, designed for lines where copper and copper alloys are not permitted-such as ammonia systems and certain battery or chemical plants. The leading "B52-" prefix marks this special material restriction, and you should confirm the exact substitutions with us before ordering.
This double-acting single-rod cylinder delivers 245.4 N of push force at 0.5 MPa from its 25 mm bore. Its short riveted body saves axial mounting depth where a round-body cylinder won't fit, and the 10 mm rod with male M8x1.25 thread couples directly to your tooling. The fixed NBR bumper at each end decelerates the stroke end-it is not an adjustable cushion, so plan for high-speed impacts accordingly.

Where the Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA25X30SB Is Used
Battery Tab Forming
In a lithium-ion cell assembly line, this 25 mm bore cylinder with 245.4 N push at 0.5 MPa precisely forms thin copper tabs without risk of copper contamination, thanks to its copper-free B52 build. The 30 mm stroke suits the short, repeatable press motion.
Ammonia Analyzer Valve
For a gas analysis cabinet handling ammonia, this copper-free cylinder actuates a small sampling valve. The 206.2 N retract force at 0.5 MPa reliably pulls the valve closed, while the compact body fits the tight instrument enclosure.
Pharma Blister Punch
On a pharmaceutical blister packing machine, this cylinder drives a 30 mm punch stroke to push tablets out of formed pockets. The 343.6 N push at 0.7 MPa clears jammed product, and the male M8x1.25 rod threads directly to the punch holder.
Is the Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA25X30SB the Right Cylinder?
For a smaller footprint, step down to the SDA20 bore, which pushes 157.1 N at 0.5 MPa-useful when space is tighter and loads are lighter. If you need more force, the SDA32 bore delivers 402.1 N at 0.5 MPa, a solid step up for heavier tooling. This B52-SDA25X30SB has a 30 mm stroke, M5x0.8 port, and a male M8x1.25 rod thread (the -B option).
Remember, this cylinder does not hold its load when air pressure is lost or the valve is centered-the piston drifts. For vertical lifting or position holding, add an external rod lock or a pilot-operated check valve. The -S magnet is built in, so you can mount AirTAC reed or electronic switches in the body grooves for position sensing.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ 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 Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA25X30SB FAQ
At 0.5 MPa, push force is 245.4 N and pull force is 206.2 N. At 0.7 MPa, push rises to 343.6 N and pull to 288.6 N. The theoretical maximum is 50 kgf at 1.0 MPa. These figures are identical to the standard SDA25X30SB; the B52- prefix only changes material composition for copper-free requirements.
B52- marks AirTAC's copper-free (copper-prohibited) build, meaning the cylinder contains no copper or copper alloys in its construction. This makes it suitable for ammonia systems and some battery, electronics, and chemical plants where copper is banned. The dimensional and performance specifications-bore, stroke, force, port, and speed-are unchanged from the standard SDA25X30SB. However, the exact material substitutions are not published, so confirm the specific parts and their compatibility with your media with us before ordering.
