The AirTAC SDA50X30H Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 30mm 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 SDA50X30H is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers 981.7 N of push force and 824.7 N of pull force at 0.5 MPa, utilizing a hard-anodized 50 mm bore and a two-way piston seal. This specific SKU features an H designation, meaning it uses fluororubber (FKM) seals for enhanced thermal and oil resistance.
A short riveted body joins the barrel, rear cover, piston, and rod to minimize overall length where a round-body unit will not fit. End stops rely on a fixed NBR bumper that decelerates the stroke rather than an adjustable air cushion. This unit lacks a piston magnet, so it cannot host position switches unless upgraded to an S option variant.

Actuates a film wrapping arm on a palletizer, where the 981.7 N push force securely tensions stretch wrap and the FKM seals withstand warm shrink-tunnel environments.
Drives a diverter gate on a beverage filling line, using the 30 mm stroke to shift glass bottles between lanes without adding excessive axial depth to the conveyor frame.
Pushes a secondary ejector pin plate on a plastic injection molding machine, utilizing the 50 kg vertical lift capacity to clear warm parts safely.
This 50 mm bore generates 981.7 N push at 0.5 MPa, sitting between the SDA40 at 628.3 N and the SDA63 at 1558.6 N. If your application must hold a load without live pressure, note that the piston drifts on air loss; an external rod lock or pilot-operated check valve is required.
When ordering, confirm the 50 mm bore, 30 mm stroke, PT1/4 port, and the female M10x1.5 rod-end thread. This SKU has no magnet and cannot take a reed or electronic switch. The FKM seal suits higher heat or oily environments, and the 20 mm rod couples directly to your load while avoiding side loading.
Quick checklist
At 0.5 MPa this cylinder provides 981.7 N push and 824.7 N pull. At 0.7 MPa it provides 1374.4 N push and 1154.5 N pull. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot host AirTAC reed or electronic switches. You must select an S option variant for sensing. Additionally, end-of-travel relies on a fixed NBR bumper, not an adjustable cushion.
