The AirTAC AirTAC SDA50X150BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 150mm 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 SDA50X150BH is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This specific configuration includes a male M18x1.5 piston rod thread for secure mechanical coupling and fluororubber (FKM) seals for enhanced thermal and oil resistance. Because the 150 mm stroke exceeds the 130 mm standard maximum for this 50 mm bore, it is manufactured as a non-standard, made-to-order unit.
The riveted body design significantly reduces overall mounting depth compared to round-body alternatives, saving valuable machine footprint. Deceleration at the stroke ends is handled by a fixed NBR bumper rather than an adjustable air cushion. This unit lacks a piston magnet, meaning it cannot support position sensing without modifying the build to the -S variant.

Executes the horizontal push-off of shrink-wrapped pallet loads in high-temperature packaging zones where FKM seals survive ambient heat better than standard rubber.
Drives heavy divert gates on merge conveyor lines, utilizing the 981.7 N extend force to reliably shift totes weighing up to 50 kg onto secondary routing tracks.
Mounts directly to injection molding platens where axial length is restricted, using the male M18x1.5 rod end to drive heavy part ejection plates over the 150 mm travel.
When sizing this actuator, 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 SDA50X150BH, the 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 plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the end of travel and does not function as a locking brake. If your application demands position holding, you must integrate an external rod lock or a pilot-operated check valve. Ensure your ordering essentials specify the PT1/4 port, the male M18x1.5 rod thread, the FKM seal option, and the non-standard 150 mm stroke.
Quick checklist
This 50 mm bore double-acting cylinder provides 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 force is 200 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No. This specific SKU lacks the -S magnet option, so it cannot accept reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion; for high-energy cycles, you should add an external shock absorber.
