The AirTAC AirTAC SDA32X20SN Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 20mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA32X20SN is a double-acting, single-rod compact cylinder engineered to deliver 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth, making it ideal for machinery where a standard round-body unit would protrude too far. The 32 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable low-friction operation.
This specific configuration includes a built-in piston magnet (the S code) enabling position detection via AirTAC reed or electronic switches seated in the body grooves. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles. Operating speed spans 30-500 mm/s, and the 12 mm rod uses an M6x1.0 female thread for load coupling.

Actuates routing lane diverters on printed circuit board assembly lines, utilizing the 20 mm stroke to shift gates rapidly without consuming valuable equipment floor depth.
Drives the mechanical folder arms on automated packaging equipment to tuck corrugated box flaps, leveraging 402.1 N of extend force to overcome board stiffness.
Pushes glass or PET bottles into parallel tracking lanes on high-speed beverage conveyors, relying on the integrated magnet to confirm the 20 mm retraction for the next cycle.
When sizing this 32 mm bore unit, consider stepping down to the SDA25 if your application only requires 245.4 N of push at 0.5 MPa, or moving up to the SDA40 if you need 628.3 N to overcome higher friction. For the SDA32X20SN, the computed safe working load is approximately 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not act as a lock. If your process must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 32 mm bore, 20 mm stroke, PT1/8 port, female rod thread, and the required magnetic sensor option.
Quick checklist
At 0.5 MPa, this double-acting 32 mm bore cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, the push increases to 563 N and the pull to 483.8 N. The theoretical maximum push is 82 kgf at the 1.0 MPa operating pressure limit.
No, the piston will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumper at each end only decelerates the piston near the stroke extremes; it does not function as a braking lock. To maintain a vertical position, you must add an external rod lock or a pilot-operated check valve.
