The AirTAC AirTAC SDA50X60BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 60mm 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 SDA50X60BH is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force at 0.5 MPa. Its short riveted body significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint in tight assemblies. The hard-anodized bore ensures smooth operation across the 30-500 mm/s speed range.
This specific configuration includes a male M18x1.5 piston rod thread for robust load coupling and FKM seals for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Drives the mechanical arms that fold major flaps on high-speed corrugated box erectors, utilizing the 60 mm stroke and 981.7 N force to overcome cardboard stiffness.
Pushes heavy totes or product bundles sideways onto spur conveyor lines, where the compact riveted body minimizes interference with adjacent guard rails.
Acts as a secondary knock-out pin driver on small injection molding machines, using the male M18x1.5 rod to thread securely into the ejection plate.
When sizing this 50 mm bore actuator, consider stepping down to the SDA40, which provides 628.3 N of push at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. For this 981.7 N output, the safe working load is approximately 589 N (about 60% of capacity), translating to a vertical lift capability of roughly 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 60 mm stroke, PT1/4 port, male M18x1.5 rod, and FKM seals. Note that a plain SDA cylinder 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. For secure load holding, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, it yields 1374.4 N push and 1154.5 N pull. The theoretical maximum push force is 200 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the -S variant for sensing capabilities. Additionally, it uses fixed NBR bumpers to decelerate at stroke ends, which are not adjustable, so external shock absorbers are recommended for high-energy loads.
