The AirTAC AirTAC SDA50X5BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 5mm 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 SDA50X5BH is a double-acting, single-rod compact cylinder engineered for minimal axial mounting depth. Its riveted body assembly significantly reduces overall length compared to conventional round-body units, making it ideal for tight machine footprints. At 50 mm bore, it generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa.
This specific SKU includes a male M18x1.5 piston rod thread for robust load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance. The 5 mm stroke is governed by a fixed NBR bumper at each end to decelerate the end stop; note this is not an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing.

Applies 981.7 N of extend force at 0.5 MPa for pressing small metal contacts in an electronics assembly line, utilizing the 5 mm stroke for rapid cycling.
Uses the male M18x1.5 rod end to securely actuate a folding mechanism on a packaging conveyor, with FKM seals surviving occasional lubricant exposure.
Fits within a 50 mm bore footprint to push rejected parts off a quality control conveyor, relying on the compact riveted body to fit between adjacent machinery.
When sizing this unit, consider stepping down to the SDA40, which provides 628.3 N of push force at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. For the SDA50X5BH, a safe working load is approximately 589 N (about 60% of the 981.7 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near stroke end and does not function as a locking brake. To maintain position, an external rod lock or pilot-operated check valve is required. Confirm your ordering essentials: 50 mm bore, 5 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals.
Quick checklist
The SDA50X5BH generates a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. At 0.7 MPa, the push force is 1374.4 N. The theoretical maximum push force is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the operational speed range is 30-500 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not act as a brake. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
