The AirTAC AirTAC SDA20X60SB Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 60mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA20X60SB is a double-acting, single-rod compact cylinder engineered to deliver 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an exceptionally short axial footprint, conserving valuable mounting depth in tight machine layouts. The internal bore is hard-anodized and utilizes a two-way piston seal for reliable pneumatic performance.
This specific configuration includes a built-in piston magnet (S) for position sensing via AirTAC reed or electronic switches fitted into the body grooves, alongside a male M6x1.0 piston rod thread (B) for direct load coupling. Deceleration at the stroke ends is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating efficiently between 30-500 mm/s, it provides a safe working load of roughly 94 N (about 60% of the 0.5 MPa push figure) and can vertically lift approximately 8 kg with a 2:1 safety margin.

Actuates the cutting tool head on an electronic PCB depaneling machine, utilizing the 60 mm stroke and male M6 rod to precisely route separation lines without stressing surrounding components.
Folds minor product carton flaps on a continuous packaging conveyor, where the 157.1 N extend force securely tucks the cardboard prior to the sealing station.
Serves as a vertical parts ejector in a small pick-and-place unit, lifting approximately 8 kg of raw plastic components with a 2:1 safety margin before the next molding cycle.
When sizing this actuator, evaluate your force requirements against adjacent bores: stepping down to the SDA16 yields 100.5 N of push at 0.5 MPa, while moving up to the SDA25 provides 245.4 N. If your mechanism must maintain a vertical position during air loss or valve centering, note that this standard cylinder will drift; the fixed NBR bumper only decelerates the end of travel and acts as neither a lock nor a brake. For secure holding, incorporate an external rod lock or pilot-operated check valve. To order, confirm the 20 mm bore, 60 mm stroke, M5x0.8 port, built-in magnet (S), and male M6x1.0 rod thread (B).
Quick checklist
This 20 mm bore double-acting cylinder generates 157.1 N push and 131.9 N pull at 0.5 MPa, increasing to 219.9 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum push force is 32 kgf at 1.0 MPa, which is the absolute maximum operating pressure.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-speed cycling, add an external shock absorber. The built-in magnet works with AirTAC reed or electronic switches in the body grooves for end-position detection.
