The 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.
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.
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.
