The AirTAC Airtac B52-SDA Non-Copper Ultra-Thin Cylinder B52-SDA20X30S is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm 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.
The B52-SDA20X30S is AirTAC's copper-free (copper-prohibited) version of the SDA20X30S compact cylinder, designed for lines where copper and copper alloys are not permitted, such as ammonia systems and certain battery, electronics, and chemical plants. This double-acting single-rod unit delivers 157.1 N push and 131.9 N pull at 0.5 MPa, with a theoretical max of 32 kgf at 1.0 MPa. Its short riveted body saves axial mounting depth where a round-body cylinder won't fit, and the hard-anodized bore ensures durability in tight spaces.
The B52- prefix indicates a copper-free build, but our data does not specify which parts are substituted or their material grades. For exact material details, please confirm with us. This model includes a built-in piston magnet (-S) for AirTAC magnetic switches, which can be reed or electronic type. The fixed NBR bumper at each end decelerates the stroke end but is not an adjustable cushion, so add an external shock absorber for high-speed or high-energy applications.

In battery production lines where copper is prohibited, this B52-SDA20X30S pushes 157.1 N at 0.5 MPa to position electrode tabs in stacking fixtures. The 30mm stroke fits tight cell-stacking modules, and the compact body saves axial depth in densely packed assembly stations.
For ammonia-based refrigeration test benches, the copper-free B52-SDA20X30S actuates a small valve linkage with 131.9 N pull at 0.5 MPa. The M5x0.8 port connects easily to existing pneumatic lines, while the fixed NBR bumper handles the low-speed cycling without needing adjustment.
In PCB conformal coating machines, this cylinder with 30mm stroke and 157.1 N push at 0.5 MPa drives a spray nozzle shuttle. The built-in magnet (-S) works with a reed or electronic switch for position feedback, and the copper-free build prevents contamination in solvent-rich environments.
To size this B52-SDA20X30S, consider the next bore down: SDA16 delivers 100.5 N push at 0.5 MPa, while the next bore up, SDA25, provides 245.4 N push at 0.5 MPa. With a safe working load of about 94 N (roughly 60% of the 157.1 N figure), this cylinder suits light to medium duty. For a vertical lift, expect approximately 8 kg capacity with a 2:1 safety margin. Remember, a plain cylinder does not hold its load on air loss or when the valve is centered-the piston drifts. For holding applications, use an external rod lock or pilot-operated check valve.
Ordering essentials for this model: bore 20 mm, stroke 30 mm, port M5x0.8, magnet (S) included, rod thread female M4x0.7 (default). The rod is 8 mm. This model is within the max standard stroke of 100 mm, so it ships as a standard unit. The B52- prefix marks the copper-free build; confirm material substitutions with us before ordering for critical applications.
Quick checklist
At 0.5 MPa, push is 157.1 N and pull is 131.9 N. At 0.7 MPa, push is 219.9 N and pull is 184.7 N. The theoretical maximum is 32 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa, with proof pressure at 1.5 MPa. Speed range is 30-500 mm/s.
B52- marks AirTAC's copper-free (copper-prohibited) build of the SDA20X30S, for lines where copper alloys are not allowed. Exact material substitutions should be confirmed with us. The fixed NBR bumper at each end only decelerates the stroke end-it is not an adjustable cushion or a lock. For high-speed applications, add an external shock absorber.
