The AirTAC AirTAC SDA32X25SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 25mm 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 SDA32X25SB 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 significantly reduces axial mounting depth, making it the ideal choice for machinery where a standard round-body unit simply cannot fit. The hard-anodized 32 mm bore operates efficiently between 30 and 500 mm/s.
This specific configuration includes a built-in piston magnet (-S) for position detection via AirTAC reed or electronic switches mounted in the body grooves, and a male M10x1.25 threaded piston rod (-B) for secure load coupling. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end of the stroke to decelerate the load.

Provides 402.1 N of extend force to securely clamp aluminum workpieces inside CNC machining centers, utilizing the male M10 rod for direct fixture attachment.
Uses the 25 mm stroke to rapidly fold corrugated cardboard flaps on automated packaging lines, where the short riveted body saves valuable axial conveyor space.
Pushes electronic connectors into printed circuit boards with precise 25 mm travel, relying on the built-in magnet to trigger AirTAC reed or electronic switches for cycle confirmation.
When sizing this 32 mm bore unit, consider stepping down to the SDA25 which provides 245.4 N of push force at 0.5 MPa for lighter duties, or stepping up to the SDA40 which yields 628.3 N at 0.5 MPa if your application demands greater thrust. For the SDA32X25SB, a safe working load is approximately 241 N (about 60% of the 402.1 N figure), allowing a vertical lift of roughly 20.5 kg with a 2:1 safety margin. Ensure you specify the PT1/8 port, the 25 mm stroke, the required magnetic sensor, and the male M10x1.25 rod end when ordering.
Keep in mind that a standard compact cylinder does not hold its position if air pressure is lost or the control valve is centered; the piston will drift. The fixed NBR bumper only decelerates the load near the stroke end and acts neither as a lock nor a brake. If your setup must maintain a vertical load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 32 mm bore 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 force is 82 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, has a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion; for high-speed operations you may need an external shock absorber. Additionally, the -B option means it has a male M10x1.25 piston rod instead of the default female M6x1.0 thread.
