The AirTAC AirTAC SDA50X50H Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 50mm 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 SDA50X50H is a double-acting single-rod compact cylinder engineered for tight axial spaces. A riveted assembly joining the barrel, rear cover, piston, and rod drastically reduces overall length compared to round-body units. Delivering 981.7 N of push force at 0.5 MPa, this 50 mm bore model features a hard-anodized inner wall and a two-way piston seal for reliable service.
This specific SKU includes an H-designated fluororubber (FKM) seal variant for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this configuration lacks the S magnet option, it cannot host 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 cutting fluid exposure.
Folds corrugated cardboard flaps on high-speed packaging lines where the short riveted body minimizes interference with moving conveyor mechanisms.
Raises and lowers 50 kg material handling gates, operating safely within the 30-500 mm/s speed range while requiring external check valves to prevent gravity drift.
When sizing this unit, evaluate your force requirements bidirectionally. Stepping down, the SDA40 provides 628.3 N of push at 0.5 MPa; stepping up, the SDA63 yields 1558.6 N at the same pressure. 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.
Confirm your ordering essentials: 50 mm bore, 50 mm stroke, PT1/4 port, female M10x1.5 rod-end thread, and FKM seals. Note that a standard actuator drifts when air is lost or the valve is centered, as the fixed bumper only decelerates near stroke end and acts as neither a lock nor a brake. To suspend a load safely without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
No. This SKU lacks the S magnet option, so it cannot support reed or electronic switches. Additionally, it uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. For high kinetic energy loads, slow the approach speed or add an external shock absorber.
