Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA63X25
The AirTAC Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA63X25 is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 25mm stroke, PT1/4 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-SDA63X25
The B52-SDA63X25 is AirTAC's copper-free (copper-prohibited) build of the SDA63X25 compact cylinder, designed for lines where copper alloys are not permitted, such as ammonia systems or certain battery and electronics plants. The leading B52- prefix marks this material restriction; exact substitution details should be confirmed with us. As a double-acting single-rod cylinder, it delivers 1558.6 N of push force at 0.5 MPa from its 63 mm bore.
Its riveted body construction keeps the axial length remarkably short, fitting into machine frames where a round-body cylinder would not. The 20 mm piston rod with M10x1.5 female thread couples directly to your tooling, while the PT1/4 ports accept standard fittings. A fixed NBR bumper at each end absorbs stroke-end impact, though it is not adjustable and should not be treated as a cushion for high-energy applications.

Where the Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA63X25 Is Used
Ammonia Plant Valve Actuation
In ammonia refrigeration systems where copper is prohibited, this copper-free B52-SDA63X25 actuates 2-inch ball valves in the compressor room. Its 1558.6 N push at 0.5 MPa overcomes valve stem friction while the compact body fits between pipe runs.
Battery Tab Forming Press
For lithium-ion cell tab bending stations, the 20 mm rod and 63 mm bore deliver 2182.1 N at 0.7 MPa to form copper tabs. The short 25 mm stroke cycles at 300 mm/s, and the copper-free construction prevents contamination in the clean assembly area.
Chemical Dosing Pump Stroke Limiter
In a chemical blending skid, this cylinder positions a dosing pump stroke adjuster. The 1401.5 N retract force pulls the mechanism back reliably, while the fixed NBR bumper handles the 25 mm stroke end without shock. PT1/4 ports connect to the existing air manifold.
Is the Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA63X25 the Right Cylinder?
For sizing, compare against the SDA50 which delivers 981.7 N push at 0.5 MPa, or step up to the SDA80 with 2513.3 N at the same pressure. This B52-SDA63X25 with a 25 mm stroke sits in the middle of the range, offering substantial force for medium-duty tasks. The safe working load is approximately 935 N (about 60% of the 1558.6 N figure), and with a 2:1 safety margin it can vertically lift roughly 79.4 kg.
This SKU has no piston magnet, so it cannot accept magnetic switches; choose the -S variant if position sensing is required. The rod end is female-threaded M10x1.5 by default. Remember that this cylinder does not hold its load if air pressure is lost - for vertical applications where drift is unacceptable, add an external rod lock or pilot-operated check valve.
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.
