About the Airtac SDA Ultra Thin Cylinder SDA50X35
The AirTAC SDA50X35 is a double-acting single-rod compact cylinder engineered to deliver a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its riveted assembly unites the barrel, rear cover, piston and rod into a highly abbreviated unit, drastically reducing axial mounting footprint compared to conventional round-body designs.
This specific configuration features a 50 mm bore, a 35 mm stroke, and a PT1/4 port. The 20 mm piston rod terminates in a standard female M10x1.5 thread. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should reduce approach speeds or utilize external shock absorbers for heavy kinetic loads.

Where the Airtac SDA Ultra Thin Cylinder SDA50X35 Is Used
Package Diverting
Actuates routing gates on logistics conveyor lines where the 824.7 N retract force easily pushes cartons weighing up to 50 kg onto secondary chutes.
Pallet Strapping
Tensions and seals polypropylene strapping heads on automated pallet wrappers, utilizing the 35 mm stroke to cycle rapidly without excessive axial depth.
Injection Mould Ejection
Ejects formed plastic parts from small injection moulding tools, relying on the 981.7 N extend force to break the part free from the cavity.
Is the Airtac SDA Ultra Thin Cylinder SDA50X35 the Right Cylinder?
Selecting this 50 mm bore provides a theoretical maximum push of 200 kgf at 1.0 MPa. If your application requires less force, stepping down to the SDA40 yields 628.3 N at 0.5 MPa, while moving up to the SDA63 provides 1558.6 N at 0.5 MPa. Based on the 981.7 N push figure, the safe working load is approximately 589 N, allowing a vertical lift of around 50 kg with a 2:1 safety margin.
When ordering, confirm the 50 mm bore, 35 mm stroke, PT1/4 port, and female M10x1.5 rod thread. Note that this SKU lacks a piston magnet, so position sensing is not supported. Furthermore, this unit will not hold a load if air pressure drops or the valve is centered; an external rod lock or pilot-operated check valve is required for secure positioning.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA50X35 FAQ
This double-acting cylinder generates a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. At 0.7 MPa, push increases to 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support 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. You must add external shock absorbers for high-energy loads.
