The AirTAC AirTAC SDA50X160BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 160mm 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 SDA50X160BH is a double-acting single-rod compact cylinder engineered for tight axial footprints. It delivers a robust 981.7 N push and 824.7 N pull at 0.5 MPa. This specific configuration includes a 160 mm stroke, which exceeds the 130 mm standard maximum for this bore size, making it a non-standard, made-to-order unit. The riveted body design drastically reduces overall mounting depth compared to conventional round-body cylinders.
This model is configured with a male M18x1.5 piston rod thread (option B) for secure mechanical coupling to your load. It also features fluororubber (FKM) seals (option H) for enhanced thermal and oil resistance. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end to decelerate the stroke. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Shifts heavy wooden pallets on a packaging line using the 981.7 N push force, while the male M18x1.5 rod threads securely into the diverter arm linkage.
Raises a 50 kg material platform in an assembly cell; the FKM seals withstand elevated ambient heat, and a pilot-operated check valve prevents drifting on air loss.
Applies downward clamping pressure on a carton sealing machine where the compact riveted body saves vertical space and the fluororubber elastomer resists glue contamination.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. At 981.7 N push, this 50 mm bore achieves a safe working load of roughly 589 N (about 60 percent of the 0.5 MPa figure) and can vertically lift approximately 50 kg with a 2:1 safety margin. If your mechanism must hold a vertical load without live air pressure, note that the piston will drift; an external rod lock or pilot-operated check valve is required, as the fixed bumper only decelerates near the stroke end.
To order, confirm the essentials: 50 mm bore, 160 mm non-standard stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals. Operating speed spans 30-500 mm/s. For high-energy cycles, consider adding an external shock absorber to protect the built-in NBR bumper.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, increasing to 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, proof pressure is 1.5 MPa, and the speed range is 30-500 mm/s.
No. This SKU lacks the -S magnet, so it cannot trigger AirTAC reed or electronic switches. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion or brake. If air pressure drops or the valve is centered, the piston will drift; you must add an external rod lock to hold a load safely.
