The AirTAC AirTAC SDA32X30S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 30mm 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 SDA32X30S is a double-acting single-rod compact cylinder engineered for tight axial spaces, delivering a push force of 402.1 N at 0.5 MPa. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, making it ideal for dense machinery layouts.
This 32mm bore variant features a 12mm piston rod and PT1/8 ports. Equipped with an -S option, it includes a built-in piston magnet for position detection using AirTAC reed or electronic switches mounted in the body grooves. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, ensuring consistent deceleration.

Drives the Z-axis plunge on a printed circuit board routing machine, utilizing the 30mm stroke and 402.1 N force to cleanly cut separation tabs.
Presses small radial bearings into electric motor end bells, where the 12mm rod and compact depth fit neatly between the chuck and frame.
Actuates a mechanical arm to fold minor flaps on a packaging line, using the integrated magnet to confirm fold completion via a reed or electronic switch.
When sizing this unit, 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 this 32mm bore, a 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. To finalize your order, confirm the 30mm stroke, PT1/8 porting, female M6x1.0 rod thread, and the required -S magnet.
Note that a standard SDA cylinder will drift and cannot hold a load if air pressure drops or the valve is centered. The fixed NBR bumper only decelerates the stroke near the end caps; it does not function as a locking brake. If your application requires static holding without live pressure, integrate an external rod lock or 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 is 563 N and pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion, so for high-speed or high-energy cycles, you should slow the approach or add an external shock absorber.
