The AirTAC AirTAC SDA32X20S 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 SDA32X20S 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 into an exceptionally short unit, drastically reducing axial mounting depth compared to conventional round-body designs. This space efficiency makes it ideal for machinery where footprint minimization is critical.
This specific configuration includes the S option, meaning a built-in piston magnet enables position detection via an AirTAC reed or electronic switch seated in the body grooves. The 32 mm bore features a 12 mm rod, a PT1/8 air port, and a female M6x1.0 rod-end thread. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, effectively decelerating the piston near stroke limits without requiring manual tuning.

Actuates routing machine gates to separate depanelized circuit boards, utilizing the 20 mm stroke and 402.1 N force to push diverts accurately within a confined electronics assembly cell.
Drives the side flap folding mechanism on a compact vertical cartoner, where the short riveted body minimizes axial intrusion into tight packaging line conveyors.
Applies 241 N of safe working pressure to seat small bearings into pump housings, relying on the built-in S magnet to trigger a solid-state switch for press completion verification.
Selecting this 32 mm bore model provides a safe working load of roughly 241 N (about 60% of its 402.1 N push capacity at 0.5 MPa), translating to a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA25 yields 245.4 N at 0.5 MPa; conversely, the SDA40 upgrades output to 628.3 N at 0.5 MPa. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load, so an external rod lock or pilot-operated check valve is necessary for strict position holding.
When preparing your RFQ, confirm the core specifications: a 32 mm bore, 20 mm stroke, PT1/8 porting, the integrated S magnet for switch sensing, and a female M6x1.0 rod-end thread to ensure proper load coupling.
Quick checklist
This double-acting cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, handles a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. For high kinetic energy loads, you should add an external shock absorber or slow the approach speed. Additionally, the bumper is not a locking device; the piston will drift if air is lost, so an external rod lock or pilot-operated check valve is required to hold a load safely.
