The AirTAC AirTAC SDA32X45SBH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 45mm 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 SDA32X45SBH is a double-acting, single-rod compact cylinder engineered with a 32 mm bore and 45 mm stroke. It provides 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. This specific configuration includes a built-in piston magnet (-S) for position sensing, a male M10x1.25 piston rod thread (-B), and fluororubber (-H) seals for enhanced thermal and oil resistance.
The riveted body design minimizes axial mounting depth compared to traditional round-body cylinders, making it highly effective for tight machine footprints. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. The built-in magnet interfaces directly with AirTAC reed or electronic switches mounted in the body grooves.

Secures aluminum workpieces in CNC machining centers, utilizing the FKM seals to withstand exposure to cutting fluids and high operating temperatures.
Drives the forming die down 45 mm in pharmaceutical packaging lines, relying on the male M10x1.25 rod end for secure tool mounting.
Actuates routing flaps on logistics conveyor belts, where the compact riveted body saves critical axial space between parallel belt sections.
When sizing this actuator, evaluate stepping down to the SDA25, which yields 245.4 N of push force at 0.5 MPa, or moving up to the SDA40, which provides 628.3 N at the same pressure. For the 32 mm bore, a safe working load is approximately 241 N (about 60% of the 402.1 N capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 32 mm bore, 45 mm stroke, PT1/8 port, male M10x1.25 rod, FKM seals, and a sensor magnet. Remember that a standard cylinder drifts when air pressure is lost; maintaining a load without live pressure requires 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 force is 563 N and the pull force is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operating speed ranges from 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not an adjustable air cushion, so external shock absorbers are recommended for high-energy loads. The included -S magnet allows you to track position using AirTAC reed or electronic switches fitted into the body grooves.
