The AirTAC AirTAC SDA32X100SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 100mm 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 SDA32X100SB is a double-acting, single-rod compact cylinder engineered to deliver a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly space-efficient unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The hard-anodized bore ensures smooth, low-friction travel across the 100 mm stroke.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, and a male M10x1.25 threaded rod end (-B) for secure mechanical coupling. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles.

Pushes corrugated cartons onto secondary packaging lines using the 402.1 N extend force, while the male M10x1.25 rod threads securely into diverter arms.
Holds aluminum castings inside machining centers; the built-in magnet triggers an electronic switch to confirm clamp engagement before the spindle starts.
Raises lightweight product trays vertically through the 100 mm stroke, requiring an external check valve since the NBR bumper cannot lock the lifted mass.
When sizing this 32 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA25 reduces the 0.5 MPa push capacity to 245.4 N, while moving up to the SDA40 increases it to 628.3 N. Based on the 402.1 N output at 0.5 MPa, the computed safe working load is approximately 241 N (60% capacity), translating to a vertical lift capability of about 20.5 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; applying an external rod lock or pilot-operated check valve is necessary for fail-safe positioning. To order, confirm the 32 mm bore, 100 mm stroke, PT1/8 port, male M10x1.25 rod thread, and the required magnetic switch.
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, the push force is 563 N and the pull force is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits. It is not an adjustable air cushion, so for high-speed or high-energy loads, you should add an external shock absorber or slow down the approach speed.
