About the Airtac SDA Ultra Thin Cylinder SDA100X20B
The AirTAC SDA100X20B is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial footprint. It generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. This specific SKU includes a male M26x1.5 piston rod thread for robust mechanical coupling to your load.
Unlike standard round-body or profile cylinders, the riveted body design significantly reduces mounting depth to fit tight machine envelopes. The bore is hard-anodized for longevity, and deceleration at the stroke ends is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this unit lacks a piston magnet, so it cannot support position sensing without upgrading to an -S variant.

Where the Airtac SDA Ultra Thin Cylinder SDA100X20B Is Used
Stamping Press Ejection
Provides the high push force needed to eject heavy formed metal panels from a stamping die, utilizing the short 20 mm stroke to save vertical press space.
Injection Mold Platen Shift
Shifts a heavy mold platen into position on an injection molding machine where axial depth is restricted but 3927 N of thrust is required.
Heavy Fixture Clamping
Secures large automotive castings in a machining fixture, leveraging the male M26x1.5 rod end for a rigid, high-force clamp.
Is the Airtac SDA Ultra Thin Cylinder SDA100X20B the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA80 provides 2513.3 N of push at 0.5 MPa; stepping up is not available as 100 mm is the largest bore in the SDA series. At 0.5 MPa, this 100 mm bore yields a safe working load of roughly 2356 N (about 60% of its rated output) and can vertically lift approximately 200.2 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder drifts when air pressure is lost or a valve is centered, as the fixed bumper only decelerates the piston near the end of travel rather than locking it. For suspended loads, integrate an external rod lock or pilot-operated check valve. To order, confirm the 100 mm bore, 20 mm stroke, PT3/8 port, male M26x1.5 rod thread, and no magnet.
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 SDA100X20B FAQ
This 100 mm bore cylinder features a PT3/8 air port. It delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
No adjustable air cushion is available; it uses a fixed NBR bumper at each end to decelerate the stroke, so you should add an external shock absorber for high-energy impacts. Additionally, this SKU lacks a piston magnet, meaning it cannot accept reed or electronic switches unless you specify the -S option.
