About the Airtac SDA Ultra Thin Cylinder SDA100X35BH
The AirTAC SDA100X35BH is a double-acting single-rod compact cylinder engineered for heavy-duty positioning within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a robust 3927 N push force at 0.5 MPa. This specific SKU is configured with a male M26x1.5 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The 100 mm bore features a hard-anodized inner wall and operates on a PT3/8 air port. End-of-stroke deceleration is handled strictly by fixed NBR bumpers rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA100X35BH Is Used
Stamping Press Ejection
Provides the high 3927 N extension force needed to eject heavy formed metal panels from progressive stamping dies within a tight machinery footprint.
Palletizer Lift Station
Raises lowerator forks handling loaded pallets, utilizing the 35 mm stroke to index goods precisely while the FKM seals withstand demanding industrial temperatures.
Injection Mold Separation
Breaks the vacuum seal on large plastic injection molds, leveraging the 32 mm rod and male M26x1.5 thread to securely pull heavy platens apart.
Is the Airtac SDA Ultra Thin Cylinder SDA100X35BH the Right Cylinder?
When sizing this actuator, consider stepping down to the SDA80, which provides 2513.3 N of push force at 0.5 MPa, or remain with this 100 mm bore for the maximum standard thrust of 3927 N. The computed safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of 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, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 100 mm bore, 35 mm stroke, PT3/8 port, male M26x1.5 rod thread, and FKM seals.
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 SDA100X35BH FAQ
This 100 mm bore double-acting cylinder exerts 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum push is 801 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU does not include a piston magnet, so it cannot support AirTAC reed or electronic switches. You would need the -S option variant to utilize the sensor grooves machined around the body.
