The AirTAC AirTAC SDA32X20H Compact Cylinder | 32mm Bore FKM 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 SDA32X20H is a double-acting single-rod compact cylinder engineered with a 32mm bore and 20mm stroke. Its riveted assembly keeps axial length minimal, saving valuable mounting depth where a conventional round-body unit would not fit. This specific SKU utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance, operating reliably across a 30-500 mm/s speed range.
Generating 402.1 N of push force and 345.6 N of pull force at 0.5 MPa, it features a 12mm piston rod and PT1/8 port. End-of-travel 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. Note that this configuration lacks a piston magnet, so it cannot directly host magnetic switches.

Pushes finished aluminum billets from a machining fixture using 402.1 N of extend force, where the FKM seals withstand elevated ambient temperatures near the spindle.
Applies brief clamping pressure on cardboard cartons passing through a high-temperature adhesive station, utilizing the 20mm stroke to minimize overall machine footprint.
Parts small plastic components from a mold cavity with a 345.6 N retract pull at 0.5 MPa, relying on the compact riveted body to fit within tight press tooling.
When sizing this actuator, evaluate your neighbors: stepping down to the SDA25 yields 245.4 N push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For the SDA32X20H, 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. To finalize your order, confirm the 32mm bore, 20mm stroke, PT1/8 port, female M6x1.0 rod thread, and the FKM seal option. Because this is a standard double-acting cylinder, it will drift and cannot hold a load if air pressure is lost or the valve is centered—implement an external rod lock or pilot-operated check valve if position holding is required.
Quick checklist
This 32mm bore double-acting cylinder provides 402.1 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum push of 82 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, proof pressure is 1.5 MPa, and the speed range is 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You would need the -S option variant for sensing capabilities. Additionally, end stops are managed by a fixed NBR bumper that decelerates the piston, which is not an adjustable air cushion.
