About the Airtac SDA Ultra Thin Cylinder SDA63X30
The AirTAC SDA63X30 is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly securely joins the barrel, rear cover, piston, and rod, yielding an exceptionally short axial footprint that slides into tight machine envelopes where conventional round bodies fail. The hard-anodized bore minimizes friction, while the integrated two-way piston seal ensures reliable actuation across the 30-500 mm/s speed band.
This specific configuration features a 20 mm piston rod and PT1/4 air ports. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke. Note that this SKU lacks the -S piston magnet, so it cannot host AirTAC reed or electronic switches; position sensing requires the -S variant. Furthermore, the end bumper only absorbs impact energy and does not function as a lock or brake to hold loads.

Where the Airtac SDA Ultra Thin Cylinder SDA63X30 Is Used
Injection Mold Ejection
Drives stripper plates out of heavy injection molding tools, utilizing the 1558.6 N extend force to break plastic parts free within confined press cavities.
Pallet Diverting Arms
Actuates routing gates on high-speed packaging conveyors, where the short 30 mm stroke quickly redirects heavy product flow without consuming valuable floor space.
Press Feed Lifting
Raises heavy steel coil stock into stamping press feed lines, safely handling loads near the 79.4 kg vertical lift threshold calculated with a 2:1 safety margin.
Is the Airtac SDA Ultra Thin Cylinder SDA63X30 the Right Cylinder?
When sizing this 63 mm bore actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80 for 2513.3 N if your application requires heavier thrust. For the SDA63X30, a safe working load is approximately 935 N (about 60 percent of the 1558.6 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin.
To finalize your order, confirm the 63 mm bore, 30 mm stroke, and PT1/4 porting. This base model has no magnet and uses a female M10x1.5 rod-end thread. Because a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, you must integrate an external rod lock or pilot-operated check valve if the mechanism needs to hold a suspended load safely in place.
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 SDA63X30 FAQ
The SDA63X30 generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push is 318 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a braking lock. This particular SKU lacks the -S magnet, meaning it cannot support reed or electronic switches; you must select the -S option for position sensing capabilities.
