The AirTAC AirTAC SDA32X55S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 55mm 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 SDA32X55S 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 merges the barrel, rear cover, and piston into an ultra-short profile, drastically reducing axial mounting depth where a conventional round-body unit would be too long. The 32 mm bore features a hard-anodized inner wall and a two-way seal for low-friction service.
Because this unit includes the S option, a built-in piston magnet enables position sensing via an AirTAC reed or electronic switch seated in the body grooves. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or utilize an external shock absorber for high-energy loads. The 12 mm rod and PT1/8 port ensure robust pneumatic and mechanical coupling.

Actuates short-stroke tool release mechanisms on machining centers where axial space is restricted but 402.1 N of extension force is required to overcome spindle spring tension.
Drives the side flap folders on automated corrugated box erectors, using the 55 mm stroke and built-in S magnet to confirm fold completion via a reed or electronic switch.
Powers a pneumatic routing gate on a sorting line, relying on the compact riveted body to fit between tight conveyor frames while pushing lightweight totes.
Selecting this 32 mm bore provides a theoretical maximum output of 82 kgf at 1.0 MPa, translating to a safe working load of roughly 241 N or a vertical lift capacity of about 20.5 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa; conversely, upgrading to the SDA40 provides 628.3 N at the same pressure. To finalize your order, confirm the 55 mm stroke, PT1/8 porting, female M6x1.0 rod thread, and the required S magnet code. Note that a standard cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is necessary to hold a load securely.
Quick checklist
At 0.5 MPa, this 32 mm bore double-acting cylinder generates 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, the push increases to 563 N and the pull to 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
No, the SDA32X55S uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-mass applications, you should slow the approach speed or install an external shock absorber to prevent damage.
