The AirTAC AirTAC SDA32X40B Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 40mm 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 SDA32X40B 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 minimizes axial mounting depth, making it ideal for machinery where space is tight. Because this SKU includes the B option, the 12 mm piston rod terminates in a male M10x1.25 thread for straightforward load coupling.
This unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning there is no field-adjustable air cushion. Operating speeds span 30-500 mm/s. Note that this specific configuration lacks a piston magnet, so it cannot directly host AirTAC reed or electronic switches without changing to an S-suffix variant.

Secures aluminum workpieces in a CNC milling vise using the male M10x1.25 rod end, providing 402.1 N of clamping force without extending the machine footprint.
Pushes corrugated cartons off a sorting line at up to 500 mm/s, where the short riveted body fits neatly within the conveyor side frame.
Drives a pneumatic label tamp head onto cases with a 40 mm stroke, relying on the fixed NBR bumper to soften the impact at the end of travel.
When sizing this 32 mm bore actuator, consider stepping down to the SDA25, which provides 245.4 N of push at 0.5 MPa, or moving up to the SDA40, which yields 628.3 N at the same pressure. For the SDA32X40B, the 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. Ensure your ordering essentials cover the 40 mm stroke, PT1/8 port, and the male M10x1.25 rod end. If the application requires holding a load during air loss or valve centering, be aware the piston will drift; the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. An external rod lock or pilot-operated check valve is required for secure positioning.
Quick checklist
At 0.5 MPa, this 32 mm bore double-acting cylinder provides 402.1 N push and 345.6 N pull. At 0.7 MPa, push increases to 563 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
No, this specific SKU lacks a piston magnet. To use AirTAC reed or electronic switches in the body grooves, you must select the S-suffix variant. Additionally, the male M10x1.25 rod end on this B-option model requires avoiding side loads to prevent premature wear.
