The AirTAC AirTAC SDA32X45B Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 45mm 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 SDA32X45B is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It delivers a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa, operating within a speed range of 30-500 mm/s. This specific SKU includes a male M10x1.25 piston rod thread for secure mechanical coupling to your load.
Because this model lacks the -S magnet option, it cannot accept AirTAC reed or electronic switches for position sensing. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, which saves space but is not a field-adjustable air cushion. For high-energy cycles, consider slowing the approach speed or adding external shock absorption.

Secures aluminum workpieces in a CNC machining center using the 402.1 N extend force, with the male M10x1.25 rod threading directly into a custom jaw.
Drives a mechanical arm to tuck corrugated box flaps at 45 mm stroke, fitting into the narrow frame of a high-speed packaging line.
Pushes lightweight parcels onto an adjacent conveyor belt, utilizing the short riveted body to minimize protrusion into the walkway.
When sizing this 32 mm bore 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. The computed safe working load for this SDA32X45B is approximately 241 N (about 60% of the 402.1 N capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Ensure your ordering essentials match this configuration: 32 mm bore, 45 mm stroke, PT1/8 port, no magnet, and the male M10x1.25 rod end.
Note that a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The fixed rubber bumper only decelerates the stroke near the end caps and does not function as a locking brake. If your application requires absolute load holding on air loss, you must integrate an external rod lock or a pilot-operated check valve.
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 cannot be adjusted like an air cushion. Additionally, because this SKU lacks the -S option, it has no piston magnet and cannot support reed or electronic switches; you would need the SDA32X45BS variant for position sensing.
