The AirTAC SDA50X15SB Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 15mm 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.
The AirTAC SDA50X15SB is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly space-efficient unit, drastically reducing axial mounting depth where a conventional round-body actuator would fail to fit. The 50 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable pneumatic performance.
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 M18x1.5 threaded piston rod (-B) for secure load coupling.

Secures heavy cast iron engine blocks onto machining centers using the 981.7 N extend force, while the short 15 mm stroke minimizes interference in tight multi-axis work zones.
Drives mechanical arms to tuck corrugated box flaps prior to sealing, utilizing the male M18x1.5 rod end for robust linkage attachment in high-speed packaging lines.
Acts as a precise 15 mm vertical stop gate for layer positioning on palletizers, where the compact riveted body saves critical vertical space within the lift framework.
When sizing this 50 mm bore actuator, consider stepping down to the SDA40, which provides 628.3 N of push force at 0.5 MPa for lighter duties, or moving up to the SDA63, which outputs 1558.6 N at 0.5 MPa if your application demands greater thrust. To finalize your order for this model, confirm the 50 mm bore, 15 mm stroke, PT1/4 port, built-in magnet, and the male M18x1.5 rod thread. Keep in mind that a standard pneumatic actuator will not hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. To maintain position safely, integrate an external rod lock or a pilot-operated check valve into your circuit.
Quick checklist
This double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa with a speed range of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to absorb end-stop impact, which is not field-adjustable. For high-speed or high-energy cycles, you should add an external shock absorber or reduce the approach speed.
