About the Airtac SDA Ultra Thin Cylinder SDA100X15SBH
The AirTAC SDA100X15SBH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly shrinks overall length compared to conventional round-body units, yielding a substantial 3927 N push at 0.5 MPa. This specific configuration includes a male M26x1.5 piston rod, a built-in magnet for position sensing, and fluororubber (FKM) seals for enhanced thermal and oil resistance.
Designed without adjustable air cushions, the bore relies on a fixed NBR bumper at each end to decelerate the stroke. Operating speeds span 30-500 mm/s, and the hard-anodized 100 mm inner wall ensures durability. For high-energy cycles, supplementing the bumper with an external shock absorber is advised to manage impact forces safely.

Where the Airtac SDA Ultra Thin Cylinder SDA100X15SBH Is Used
Press Fit Bushings
Drives a 200 kg vertical load to seat heavy industrial bushings into automotive transmission housings, utilizing the 3927 N extend force and short 15 mm stroke.
Plastic Injection Mold Locking
Secures heavy injection mold halves in high-temperature environments using the FKM seals, providing reliable clamping without excessive axial machine depth.
Heavy Stamping Pin Extraction
Ejects thick guide pins from hot metal stamping dies, where the male M26x1.5 rod end couples directly to the tooling and the sensor magnet tracks ejection completion.
Is the Airtac SDA Ultra Thin Cylinder SDA100X15SBH the Right Cylinder?
Selecting this 100 mm bore provides a safe working load of roughly 2356 N (about 60% of the 3927 N push at 0.5 MPa) and a vertical lift capacity of approximately 200.2 kg with a 2:1 margin. If your application requires less force, the SDA80 offers 2513.3 N at 0.5 MPa; as the largest standard SDA size, stepping up beyond 100 mm requires a different body style. When ordering, confirm the 15 mm stroke, PT3/8 port, male M26x1.5 rod thread, the -S magnet for reed or electronic switches, and the -H FKM seal option.
Because a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, this model cannot independently hold a load. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a mechanical lock. If your machine demands fail-safe position holding, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 SDA100X15SBH FAQ
This 100 mm bore 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 is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports speeds of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-energy cycles, add an external shock absorber. Additionally, it does not hold position on air loss; the piston drifts, so an external rod lock or pilot-operated check valve is required for fail-safe load holding.
