About the Airtac SDA Ultra Thin Cylinder SDA100X90B
The AirTAC SDA100X90B is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. It delivers a substantial 3927 N push force at 0.5 MPa, utilizing a robust Ø32 mm piston rod and PT3/8 air ports. The riveted body design significantly reduces overall mounting length compared to conventional round-body units, saving valuable machine depth in tight layouts.
This specific SKU includes a male-thread M26x1.5 piston rod end for secure mechanical load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. Note that this configuration lacks a piston magnet, so it cannot host reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA100X90B Is Used
Heavy Press Assembly
Drives robust bearing blocks into housings on an automotive assembly line, utilizing the 3927 N push force to seat components firmly without requiring a massive profile body.
Injection Mold Ejection
Ejects dense plastic pallets from molding machinery where the short 90 mm stroke and male M26x1.5 rod end provide rigid, space-efficient ejection force.
Palletizer Lift Station
Raises heavy product layers within a compact palletizing cell, achieving a 200.2 kg safe vertical lift capacity while conserving vertical machine envelope.
Is the Airtac SDA Ultra Thin Cylinder SDA100X90B the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA80 yields 2513.3 N of push force at 0.5 MPa, which may suffice for lighter duties, whereas this 100 mm bore provides a maximum theoretical output of 801 kgf at 1.0 MPa. For safe vertical lifting, anticipate a working load around 2356 N (roughly 200.2 kg with a 2:1 safety margin). Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 100 mm bore, 90 mm stroke, PT3/8 port, male M26x1.5 rod thread, and no sensor 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 SDA100X90B FAQ
This double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, a proof pressure of 1.5 MPa, and speeds of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion; high-speed applications may need external shock absorbers. Additionally, this SKU lacks the -S option, so it has no piston magnet and cannot support reed or electronic switches. It features a male M26x1.5 rod thread instead of the standard female thread.
