The AirTAC AirTAC SDA50X5SBH 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 SDA50X5SBH is a double-acting compact cylinder engineered for tight axial spaces, delivering a robust 981.7 N push force at 0.5 MPa. Its riveted body assembly drastically reduces mounting depth compared to conventional round-body units, making it highly effective for machinery where footprint minimization is critical. The bore is hard-anodized, and the piston relies on a two-way seal for reliable actuation.
This specific configuration includes a built-in piston magnet (-S) for position detection using an AirTAC reed or electronic switch, a male-thread piston rod end (-B) sized at M18x1.5 for secure load coupling, and fluororubber (-H) seals for enhanced thermal and oil resistance. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. With a mere 5 mm stroke, it excels at high-force micro-clamping, though side loading must be strictly avoided on this short rod.

Provides high-force 981.7 N micro-clamping of heavy cast iron engine blocks during CNC milling, utilizing the 5 mm stroke to lock parts securely without consuming valuable machining envelope.
Delivers rapid, short-stroke pressing force to fold and secure corrugated packaging flaps in high-speed automated boxing lines, benefiting from the FKM seals in heated glue environments.
Acts as a compact knockout pin actuator for plastic injection molds, using the male M18x1.5 rod thread to drive the plate and the fixed NBR bumper to soften the end impact.
When sizing this actuator, evaluate your force margins carefully. If you step down to an SDA40, the output drops to 628.3 N at 0.5 MPa, whereas stepping up to an SDA63 provides 1558.6 N. For this 50 mm bore, the safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. If your sequence demands position holding upon air loss, note that the piston will drift; an external rod lock or pilot-operated check valve is required. To order, confirm the 50 mm bore, 5 mm stroke, PT1/4 port, male M18x1.5 rod, FKM seals, and the integrated magnet.
Quick checklist
This 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 force is 200 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, a standard compact cylinder cannot hold a load when air is lost or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the piston near the stroke end and does not act as a lock or brake. To maintain a vertical load without live pressure, you must install an external rod lock or a pilot-operated check valve.
