The AirTAC AirTAC SDA32X40H Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 40mm 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 SDA32X40H is a double-acting single-rod compact cylinder engineered with a 32mm bore and 40mm stroke. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. This specific SKU includes an H designation, meaning it uses fluororubber (FKM) seals for enhanced high-temperature and oil-resistance requirements compared to the standard NBR configuration.
The short riveted body significantly reduces axial mounting depth, making it ideal for machinery where a standard round-body cylinder would be too long. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating at speeds of 30-500 mm/s, this unit lacks a piston magnet and therefore cannot support magnetic sensing; adding the -S option is required for reed or electronic switch integration.

Actuates tooling arms in machining centers where the FKM seals withstand elevated ambient heat and the shallow body depth fits tight carousel envelopes.
Drives sealing jaws on packaging lines exposed to oil mists and higher temperatures, utilizing the 402.1 N push force to close carton flaps securely.
Provides compact ejection force for small plastic parts, saving machine footprint while the fixed NBR bumper absorbs the end stop without external adjustments.
When sizing this unit, evaluate your force needs carefully. Stepping down, the SDA25 provides 245.4 N of push at 0.5 MPa; stepping up, the SDA40 yields 628.3 N at the same pressure. Based on the 402.1 N push rating, a safe working load is approximately 241 N (about 60% capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Ensure you specify the 32mm bore, 40mm stroke, PT1/8 port, female M6x1.0 rod thread, and the FKM seal when ordering.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered. The piston will drift, and the fixed bumper only decelerates the stroke near its end without acting as a mechanical lock. If your application requires strict load holding on air loss, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 32mm bore double-acting cylinder provides a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 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.
No, this specific SKU does not have a piston magnet. To use AirTAC reed or electronic switches in the body grooves, you must order the -S variant. Additionally, this version uses FKM seals for better oil and heat resistance, and it relies on a fixed NBR bumper for end deceleration rather than an adjustable cushion.
