The AirTAC AirTAC SDA50X100SBH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 100mm 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 SDA50X100SBH is a double-acting single-rod compact cylinder engineered for tight axial footprints, delivering 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This specific configuration includes a built-in piston magnet (-S) for position sensing, a male M18x1.5 threaded rod end (-B), and fluororubber (-H) seals for enhanced thermal and oil resistance. A 100 mm stroke operates within the 130 mm standard limit for this 50 mm bore.
The short riveted body drastically reduces mounting depth compared to conventional round-body units, making it highly effective for machinery where axial space is strictly limited. Instead of an adjustable air cushion, the internals rely on a fixed NBR bumper at each end to decelerate the stroke. Because the piston drifts when air pressure is lost, an external rod lock or pilot-operated check valve is required if the load must be held in place.

Executes the 100 mm push-off stroke to divert filled cartons onto an outbound packaging conveyor, utilizing the 981.7 N extend force to overcome sliding friction.
Mounts flush against the mold platen to actuate an ejection pin, where the FKM seals withstand high ambient radiant heat and the male M18x1.5 rod secures the tooling.
Raises a 50 kg material handling gate through its 100 mm travel, requiring an external pilot-operated check valve to prevent gravity-driven drift when the air supply is centred.
When sizing this unit, 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. For the SDA50 itself, the safe working load is approximately 589 N (about 60% of the 981.7 N figure at 0.5 MPa), which translates to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. To confirm your ordering essentials for this model: specify the 50 mm bore, 100 mm stroke, PT1/4 port, the required -S magnet for reed or electronic switches, the -B male M18x1.5 rod thread, and the -H FKM seal option.
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 force is 200 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, a proof pressure of 1.5 MPa, and a speed range of 30-500 mm/s.
It uses a fixed NBR bumper at each end to absorb impact; this is not an adjustable air cushion, so you should slow the approach speed or add an external shock absorber for high-energy loads. The built-in magnet (-S) allows you to mount AirTAC reed or electronic switches directly into the body grooves for precise position detection.
