The AirTAC AirTAC SDA32X90SBH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 90mm 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 SDA32X90SBH is a double-acting single-rod compact cylinder engineered for tight axial spaces. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. This specific configuration includes a male M10x1.25 piston rod thread for secure mechanical load coupling, alongside an integrated piston magnet for position sensing. The fluororubber (FKM) seal variant provides enhanced thermal and oil resistance for demanding environments.
Its riveted body assembly minimizes overall mounting depth compared to conventional round-body units. End-of-travel deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion. Operating speed ranges from 30-500 mm/s, and the body features standard grooves designed to accept AirTAC reed or electronic switches.

Secures aluminum workpieces in CNC machining centers. The FKM seals resist cutting fluid contamination while the 402.1 N push force locks the part firmly against locating pins.
Applies consistent downward pressure on cardboard carton flaps during high-temperature adhesive sealing. The 90mm stroke provides ample travel for varying box heights.
Drives a sorting diverter arm on a packaging conveyor. The integrated magnet allows reed or electronic switches to confirm gate position before downstream products arrive.
When sizing this unit, evaluate stepping down to the SDA25 which provides 245.4 N of push at 0.5 MPa, or moving up to the SDA40 which yields 628.3 N at the same pressure. For the 32mm bore at 0.5 MPa, the safe working load is approximately 241 N (about 60% of the 402.1 N output), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact configuration: 32mm bore, 90mm stroke, PT1/8 port, built-in magnet (S), male rod thread (B), and FKM seals (H). Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required.
Quick checklist
This 32mm bore double-acting cylinder outputs 402.1 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston near stroke completion; it is not an adjustable air cushion. Because it is a standard double-acting cylinder, it will drift and lose position if air supply is cut or the valve is centered. An external rod lock or pilot-operated check valve is necessary for fail-safe load holding.
