The AirTAC AirTAC SDA32X20SBH 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 SDA32X20SBH is a double-acting, single-rod compact cylinder engineered for tight axial spaces. A riveted assembly unites the barrel, rear cover, piston, and rod, drastically reducing mounting depth compared to round-body units. It delivers a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. This specific configuration includes a male M10x1.25 piston rod end, a built-in magnetic sensor ring, and high-temperature fluororubber (FKM) seals.
The 32 mm bore features a hard-anodized inner wall and a two-way piston seal for low friction. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. Circumferential grooves accept AirTAC reed or electronic switches to track piston position.

Secures aluminum housings inside machining centers. The 20 mm stroke provides rapid clamping, while FKM seals resist coolant mist and elevated ambient temperatures.
Pushes formed plastic bottles out of a continuous extrusion line. The short riveted body minimizes footprint on the conveyor frame, and the male M10x1.25 rod threads directly into the ejection fork.
Diverts populated circuit boards into testing lanes. The built-in magnet pairs with an electronic switch to confirm gate position at speeds up to 500 mm/s.
When sizing this 32 mm bore, stepping down to the SDA25 yields 245.4 N of push force at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For this 20 mm stroke model, the 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 standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To hold a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 32 mm bore, 20 mm stroke, PT1/8 port, male M10x1.25 rod (-B), magnet (-S), and FKM seals (-H).
Quick checklist
This 32 mm bore double-acting cylinder generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. At 0.7 MPa, push increases to 563 N. The theoretical maximum push force 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 only decelerates the piston near the stroke end and does not act as a brake. For vertical load holding, you must add an external rod lock or a pilot-operated check valve.
