The AirTAC AirTAC SDA80X55SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 55mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X55SB is a double-acting, single-rod compact cylinder engineered to deliver substantial force within a minimal axial footprint. By utilizing a riveted assembly that joins the barrel, rear cover, piston, and rod, this unit achieves an exceptionally short overall length compared to conventional round-body designs. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This specific configuration includes a built-in piston magnet (S) for direct mounting of AirTAC reed or electronic switches along the body grooves, and a male M22x1.5 threaded piston rod (B) for secure load coupling. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, operating effectively at speeds between 30 and 500 mm/s without requiring an adjustable air cushion.

Provides robust clamping force for holding heavy chassis components during robotic MIG welding operations, where the short body depth prevents interference with welding torches.
Actuates heavy diverting arms on high-throughput packaging conveyors to route loaded pallets, utilizing the 55 mm stroke to clear the transport lane quickly.
Ejects dense stamped metal parts from hydraulic press beds, using the 2513.3 N extend force to break the part free from the die surface reliably.
When sizing this model, compare its 2513.3 N push force at 0.5 MPa against adjacent bores: stepping down to the SDA63 yields 1558.6 N, while stepping up to the SDA100 provides 3927 N. Based on the 0.5 MPa rating, a safe working load is approximately 1508 N (60% capacity), allowing for a vertical lift of roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 55 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the required magnetic sensor option.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the directional valve is centered; the piston will drift, and the fixed rubber bumper only decelerates near the stroke end without acting as a mechanical lock. If your application demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 80 mm bore cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions at speeds between 30 and 500 mm/s.
No, it uses a fixed NBR bumper at each end to absorb end-stop impact rather than an adjustable air cushion, so external shock absorbers may be needed for high-energy cycles. Additionally, the -B code indicates a male M22x1.5 threaded piston rod, whereas the default SDA configuration uses a female M14x1.5 thread.
