The AirTAC AirTAC SDA50X150SBH 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 SDA50X150SBH is a double-acting, single-rod compact cylinder engineered for tight axial footprints. Its riveted assembly keeps overall length minimal where conventional round bodies cannot fit. Delivering 981.7 N of push force at 0.5 MPa, this unit steps up to a 20 mm piston rod and PT1/4 ports. The -H code specifies fluororubber (FKM) seals for enhanced thermal and oil resistance.
This configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The -B option provides a male M18x1.5 threaded rod end for secure mechanical coupling. Because the 150 mm stroke exceeds the 130 mm standard maximum for this bore, it is produced as a made-to-order item. End-stops rely on a fixed NBR bumper rather than an adjustable air cushion.

Drives the sealing jaws on vertical form-fill-seal equipment, utilizing the 981.7 N extend force to crimp heated film pouches securely despite elevated ambient packaging room temperatures.
Pushes loaded pallets onto secondary processing lines, where the 150 mm extended reach clears the conveyor frame and the male M18x1.5 rod threads securely mount the deflector plate.
Opens and closes high-temperature sterilization oven doors, leveraging the FKM seal variant to maintain integrity in thermal environments that would degrade standard NBR rubber.
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. At 981.7 N push, this 50 mm bore handles a safe working load of roughly 589 N (about 60 percent capacity) or a 50 kg vertical lift with a 2:1 safety factor. If your mechanism must maintain position during air loss or valve centering, add an external rod lock or pilot-operated check valve, as the piston will drift.
To order correctly, confirm the 50 mm bore, 150 mm non-standard stroke, PT1/4 porting, FKM seals, the male M18x1.5 rod thread, and the integrated switch magnet. Operating speed spans 30-500 mm/s. For high kinetic energy at stroke ends, install external shock absorbers since the standard NBR bumper only decelerates the impact and cannot act as a brake.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, it yields 1374.4 N push and 1154.5 N pull. The theoretical maximum push is 200 kgf at the 1.0 MPa operating pressure limit.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. For high-speed or high-mass loads, you should slow the approach speed or install an external shock absorber to prevent impact damage.
