The AirTAC AirTAC SDA32X85B Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 85mm 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 SDA32X85B 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 short riveted body integrates the barrel, rear cover, piston, and rod into a highly space-efficient package, drastically reducing axial mounting depth compared to traditional round-body units. This specific SKU is configured with a male M10x1.25 piston rod thread for direct load coupling.
This 32 mm bore model operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this unit lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches. With an 85 mm stroke, it approaches the 130 mm maximum standard stroke for this bore size, making it well-suited for longer travel compact actuation without requiring a custom made-to-order unit.

Drives tooling arms in CNC machining centers where the 402.1 N push force and 85 mm stroke securely index cutting tools within a tight footprint.
Actuates routing gates on packaging conveyors, using the male M10x1.25 rod end to push parcels efficiently along sorting lines.
Ejects molded parts from small injection molds, leveraging the compact riveted body to fit within narrow machine frames.
When sizing this actuator, 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 the SDA32X85B, the safe working load is approximately 241 N (about 60% of the 402.1 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder like this does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For applications requiring a locked load, an external rod lock or pilot-operated check valve is necessary. Confirm your ordering essentials: 32 mm bore, 85 mm stroke, PT1/8 port, male M10x1.25 rod thread, and no sensor magnet.
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. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No. This model uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion; for high-speed applications, consider an external shock absorber. Additionally, this specific SKU lacks the -S magnet option, so it cannot host AirTAC reed or electronic switches.
