The AirTAC AirTAC SDA32X85S 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 SDA32X85S 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, piston, and rod into a highly shortened axial footprint, conserving valuable machine space where conventional round-body units fail to fit. The internal bore is hard-anodized and paired with a two-way piston seal for prolonged operational life.
This 85 mm stroke configuration includes an integrated piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers to prevent impact damage.

Actuates a routing flap on a logistics sorting line, utilizing the 85 mm stroke to redirect parcels efficiently into secondary chutes.
Positions a vertical drill head over printed circuit boards, leveraging the 402.1 N extend force to maintain stable downward pressure.
Drives a mechanical arm to tuck minor flaps on automated case erectors before tape or adhesive application.
Selecting this 32 mm bore provides a theoretical safe working load of roughly 241 N (about 60% of the 402.1 N push figure at 0.5 MPa), translating to a vertical lift capacity near 20.5 kg with a 2:1 safety margin. If your application demands less force, stepping down to the SDA25 yields 245.4 N at 0.5 MPa, while upgrading to the SDA40 increases output to 628.3 N at 0.5 MPa. Be aware that a standard SDA body drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load; utilize an external rod lock or pilot-operated check valve if position holding is critical. Ordering essentials confirm a 32 mm bore, 85 mm stroke, PT1/8 port, built-in magnet, and a female M6x1.0 rod-end thread.
Quick checklist
This double-acting 32 mm bore 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, handles a proof pressure of 1.5 MPa, and functions across a temperature span of -20 to +70 C.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-speed operations, consider adding external shock absorbers. The included -S piston magnet allows you to track position using AirTAC reed or electronic switches mounted in the body grooves.
