The AirTAC AirTAC SDA32X5SN Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 5mm 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 SDA32X5SN is a double-acting, single-rod compact cylinder engineered for extremely tight axial spaces. It delivers a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. The short riveted body design integrates the barrel, rear cover, and piston, significantly reducing mounting depth compared to round-body alternatives.
This unit includes a built-in piston magnet (-S) compatible with AirTAC reed or electronic switches via body grooves. The 12mm rod features an M6x1.0 female thread, and end-stops rely on a fixed NBR bumper rather than an adjustable air cushion. With a 5mm stroke, it is purpose-built for high-force micro-movements.

Ideal for popping machined aluminum parts out of a CNC fixture using a brief 5mm jab with 402.1 N of extend force.
Provides a precise micro-stroke to lower test probes onto populated circuit boards without overshooting the target.
Trips a heavy-duty mechanical latch mechanism on an automated assembly line where a short, high-force 5mm shift is required.
For this 32mm bore, the 402.1 N push at 0.5 MPa yields a safe working load around 241 N (roughly 60% capacity) and a vertical lift capability of about 20.5 kg with a 2:1 safety margin. If your application requires less force, the SDA25 provides 245.4 N; if you need more power, the SDA40 offers 628.3 N. Note that a plain SDA cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered—install an external rod lock or pilot-operated check valve if position holding is critical. When ordering, confirm the 32mm bore, 5mm stroke, PT1/8 port, female rod thread, and the required magnetic sensor option.
Quick checklist
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum push force is 82 kgf at the 1.0 MPa operating pressure limit.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake. Furthermore, it cannot hold a load if air is lost; an external rod lock or pilot-operated check valve is required for fail-safe position holding.
