The AirTAC AirTAC SDA32X85SB 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 SDA32X85SB is a double-acting single-rod compact cylinder engineered for tight axial mounting spaces. It delivers 402.1 N of push force and 345.6 N of pull force at 0.5 MPa, operating within a 30-500 mm/s speed range. This specific configuration includes an 85 mm stroke, a built-in piston magnet, and a male M10x1.25 piston rod end.
The riveted body design drastically reduces overall length compared to standard round-body cylinders, making it ideal for space-constrained machinery. Instead of an adjustable air cushion, the unit relies on a fixed NBR bumper at each end to decelerate the piston near stroke limits. For high-energy cycles, adding an external shock absorber is recommended. The integrated magnet allows seamless positioning feedback when paired with AirTAC reed or electronic switches mounted in the body grooves.

Ejects finished aluminum parts from a machining center fixture using a reliable 402.1 N push force, with the male M10x1.25 rod threading directly into the ejection platen.
Folds corrugated cardboard flaps on a continuous packaging line, where the short riveted body saves valuable axial depth within the tight conveyor frame.
Actuates a sorting diverter on a bottling conveyor, using the built-in magnet and an electronic switch to confirm gate position at both ends of the 85 mm travel.
Selecting this 32 mm bore provides a safe working load of roughly 241 N (about 60% of the 402.1 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA25 yields 245.4 N at 0.5 MPa, while moving up to the SDA40 provides 628.3 N. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end rather than locking the load, so utilize an external rod lock or pilot-operated check valve if position holding is critical. When ordering, confirm the 32 mm bore, 85 mm stroke, PT1/8 port, male M10x1.25 rod thread, and the required magnetic sensor option.
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 on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston, which is not field-adjustable like a standard air cushion. If your machine cycle runs at high speeds or moves heavy masses, you should slow the approach speed or install an external shock absorber to prevent impact damage.
