About the Airtac SDA Ultra Thin Cylinder SDA100X80SB
The AirTAC SDA100X80SB is a double-acting, single-rod compact cylinder engineered to deliver substantial force within a minimal axial envelope. Utilizing a riveted assembly that permanently joins the barrel, rear cover, piston, and rod, this unit saves crucial mounting depth where conventional round-body or profile cylinders cannot fit. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, peaking at a theoretical 801 kgf at 1.0 MPa.
This specific configuration includes the S option for a built-in piston magnet, enabling position detection via an AirTAC reed or electronic switch housed in the body grooves. The B option provides a male M26x1.5 threaded piston rod end for secure mechanical coupling. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the load; it is not an adjustable air cushion, so high kinetic energy applications may require external shock absorbers.

Where the Airtac SDA Ultra Thin Cylinder SDA100X80SB Is Used
Automotive Press Ejection
Ejecting heavy stamped metal panels from hydraulic presses requires high force over a short distance; the 3927 N push at 0.5 MPa reliably clears the part from the lower die.
Pallet Dispenser Separation
Separating the bottom empty pallet from a magazine stack demands substantial pull force, utilizing the 3524.9 N retract capacity at 0.5 MPa to overcome stack friction.
Heavy Steel Plate Alignment
Squaring thick steel plates on a roller conveyor before welding benefits from the 32 mm rod diameter and male M26x1.5 thread, providing a rigid push interface to true the material.
Is the Airtac SDA Ultra Thin Cylinder SDA100X80SB the Right Cylinder?
When sizing this 100 mm bore model, stepping down to the SDA80 yields 2513.3 N of push force at 0.5 MPa, making the SDA100X80SB the necessary choice when the smaller bore cannot overcome the load. Because 100 mm is the largest standard SDA bore, exceeding this capacity requires a different cylinder family entirely. For your ordering essentials, confirm the 100 mm bore, 80 mm stroke, PT3/8 port, built-in magnet (S), and male M26x1.5 rod thread (B). Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near stroke end and does not function as a lock or brake. To hold a vertical load safely without live pressure, integrate an external rod lock or a pilot-operated check valve.
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 SDA100X80SB FAQ
This 100 mm bore double-acting cylinder provides 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 between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high energy loads, slow the approach or add external shock absorbers. Position sensing is enabled by the built-in magnet (S option), which works with AirTAC reed or electronic switches mounted in the body grooves.
