The AirTAC SDA50X15S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 15mm 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 SDA50X15S is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space savings are critical. The 50 mm bore features a hard-anodized inner wall and a two-way piston seal for prolonged operational life.
This specific configuration includes a built-in piston magnet (-S) for position detection using an AirTAC reed or electronic switch mounted in the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Because this is a short 15 mm stroke unit, the 20 mm piston rod provides a robust interface for coupling to loads while minimizing side-load risks.

Drives the short folding arm on a packaging line to tuck corrugated carton flaps, utilizing the 981.7 N push force to overcome cardboard resistance within a tight machine frame.
Extends 15 mm to push alignment pins against circuit boards during conveyor transfer, using the built-in magnet to confirm pin retraction before the conveyor advances.
Acts as a compact stop block for lightweight pallets entering a wrapping station, where the short riveted body minimizes protrusion into the walking aisle.
When sizing this unit, evaluate your force margins carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, whereas stepping up to the SDA63 provides 1558.6 N. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining a vertical load requires an external rod lock or a pilot-operated check valve. To order, confirm the 50 mm bore, 15 mm stroke, PT1/4 port, built-in magnet, and female M10x1.5 rod-end thread.
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 between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is not an adjustable air cushion. Additionally, the bumper only absorbs end-stop impact and does not function as a lock or brake. If your application must hold a vertical load without live air pressure, you must install an external rod lock or a pilot-operated check valve.
