About the Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA20X25SB
The B52-SDA20X25SB is AirTAC's copper-free (copper-prohibited) version of the SDA20X25SB compact cylinder. The leading "B52-" prefix designates a build where copper and copper alloys are not permitted, making it suitable for ammonia systems and certain battery, electronics, or chemical plants. The exact material substitutions should be confirmed with us before ordering.
This double-acting, single-rod cylinder delivers 157.1 N of push force at 0.5 MPa. Its short riveted body saves axial mounting depth where a round-body cylinder won't fit. The male-thread rod end (M6x1.0) couples directly to your tooling, while the built-in magnet (S) works with AirTAC reed or electronic switches for position sensing.

Where the Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA20X25SB Is Used
Battery Tab Forming
In a lithium-ion cell assembly line, the 157.1 N push at 0.5 MPa forms thin copper tabs without risk of copper contamination in the production area, thanks to the B52- copper-free build.
Ammonia Leak Test Rig
The copper-free construction suits a test fixture cycling a valve in an ammonia refrigeration plant. The 25mm stroke and 131.9 N pull at 0.5 MPa retract a probe between test cycles.
Carton Ejector
On a packaging line, this cylinder pushes finished cartons off a conveyor. The 219.9 N push at 0.7 MPa handles the load, and the compact body fits the tight space under the discharge chute.
Is the Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA20X25SB the Right Cylinder?
For a 20mm bore with a 25mm stroke, the B52-SDA20X25SB offers a middle ground in the compact line. If you need less force, step down to the SDA16 which provides 100.5 N push at 0.5 MPa. For more capacity, step up to the SDA25 with 245.4 N push at 0.5 MPa. This model uses an M5x0.8 port and has a max standard stroke of 100mm.
Remember that a plain cylinder won't hold its load if air pressure is lost or the valve is centered-the piston drifts. The fixed NBR bumper only decelerates the piston near stroke end; it's not a lock or brake. For holding applications, add an external rod lock or pilot-operated check valve. This unit includes the magnet (S) and male-thread rod (B).
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.
