The AirTAC AirTAC SDA32X25SBH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 25mm 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 SDA32X25SBH 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 defining characteristic is a short, riveted body that integrates the barrel, rear cover, piston, and rod. This space-saving architecture drastically reduces axial mounting depth compared to conventional round-body units, making it highly advantageous for tight machine footprints.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also features a male-thread M10x1.25 piston rod (-B) for secure load coupling, and high-temperature fluororubber (-H) seals. End-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.

Actuates routing machine gates in electronics fabrication, where the compact 32 mm body saves axial depth and the FKM seals withstand localized thermal processing.
Provides 402.1 N of extend force to clamp heated blister packaging molds, utilizing the male M10x1.25 rod for rigid mechanical coupling.
Drives short-stroke tensioning arms on automated looms, relying on the integrated magnet to trigger electronic switches for precise thread positioning.
When sizing this 32 mm bore unit, stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. Based on the 402.1 N output, the safe working load is approximately 241 N (60% capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Ensure your ordering essentials include the PT1/8 port, 25 mm stroke, male M10x1.25 rod, and FKM seals. Note that this cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift and the fixed bumper only decelerates near the stroke end. For suspended loads, an external rod lock or pilot-operated check valve is mandatory.
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 on filtered air between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high kinetic energy applications, you should slow the approach speed or add an external shock absorber. Additionally, it does not function as a brake; if air is lost, the piston drifts and requires an external rod lock to hold position.
