The AirTAC AirTAC SDA50X130BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 130mm 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 SDA50X130BH is a double-acting single-rod compact cylinder engineered for tight axial footprints. Its riveted assembly keeps the overall length minimal where a conventional round-body unit would not fit. Generating 981.7 N of push force at 0.5 MPa, it utilizes a hard-anodized bore and a two-way piston seal for reliable pneumatic performance.
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 50 mm bore uses PT1/4 ports and relies on fixed NBR bumpers at each end to decelerate the stroke. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Secures heavy cast iron engine blocks during machining operations, utilizing the 981.7 N push force and FKM seals to withstand coolant exposure.
Ejects completed shrink-wrapped pallet loads from a packaging cell, where the 130 mm stroke and male M18x1.5 rod end provide robust mechanical ejection.
Raises and lowers intermediate material handling gates, safely handling a 50 kg vertical load thanks to a 2:1 safety margin at 0.5 MPa.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while moving up to the SDA63 provides 1558.6 N. With this 50 mm bore delivering 981.7 N at 0.5 MPa, a safe working load is approximately 589 N (60 percent capacity), translating to a vertical lift capability of about 50 kg with a 2:1 safety factor.
Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end rather than locking the piston. For applications requiring suspended load security, incorporate an external rod lock or pilot-operated check valve. To order, confirm the 50 mm bore, 130 mm stroke, PT1/4 port, male M18x1.5 rod, and FKM seal specifications.
Quick checklist
This double-acting 50 mm bore cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, push increases to 1374.4 N and pull to 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S magnet option, so it cannot host AirTAC reed or electronic switches. Additionally, it relies on fixed NBR bumpers to decelerate the stroke ends rather than an adjustable air cushion, so external shock absorbers may be needed for high-energy loads.
