The AirTAC AirTAC SDA100X70SB Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 70mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA100X70SB is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly yields a 70 mm stroke from a 100 mm bore, generating 3927 N of push force at 0.5 MPa. The -S code denotes an integrated piston magnet for position sensing, while the -B code specifies a male M26x1.5 threaded rod end for secure mechanical load coupling.
This model relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not a field-adjustable air cushion. Operating between 0.15 and 1.0 MPa at speeds of 30-500 mm/s, the hard-anodized 100 mm bore handles substantial work. Because the piston drifts without live air pressure, an external rod lock is necessary for fail-safe load holding.

Provides the high 3927 N extension force needed to eject heavy formed metal panels from a stamping die, utilizing the male M26x1.5 thread for rigid tooling attachment.
Raises heavy palletized loads in a compact assembly machine, achieving a 200.2 kg vertical lift with a 2:1 safety margin while saving axial mounting depth.
Drives the sealing head against large industrial packaging crates, where the fixed NBR bumper absorbs the end-stop impact without requiring external adjustment.
When sizing this 100 mm bore actuator, stepping down to the SDA80 yields 2513.3 N of push force at 0.5 MPa, making the SDA100X70SB the preferred choice when you need the maximum standard 801 kgf capacity at 1.0 MPa. A computed safe working load is approximately 2356 N (about 60% of the 3927 N figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
To finalize your order, confirm the 100 mm bore, 70 mm stroke, PT3/8 port, and the male M26x1.5 rod thread. The built-in magnet supports AirTAC reed or electronic switches. Remember that a plain compact cylinder does not hold its position if air is lost; add a pilot-operated check valve if your application requires mid-stroke locking.
Quick checklist
This 100 mm bore model uses a PT3/8 port and generates 3927 N push / 3524.9 N pull at 0.5 MPa, and 5497.8 N push / 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No, it uses a fixed NBR bumper to decelerate at stroke ends, which is not an adjustable air cushion. Additionally, it does not hold its load if air pressure is lost; the piston will drift. For load holding, you must use an external rod lock or pilot-operated check valve.
