The AirTAC SDA80X100 Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 100mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X100 is a double-acting single-rod compact cylinder engineered to deliver 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. Featuring a hard-anodized 80 mm bore, it provides substantial thrust within a minimal axial footprint. The short riveted body integrates the barrel, rear cover, piston, and rod, saving valuable mounting depth where a conventional round-body unit would be too long.
This model incorporates a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Operating at speeds between 30 and 500 mm/s, it utilizes a PT3/8 port and a 25 mm piston rod. This specific SKU is configured without a piston magnet and therefore cannot directly host magnetic switches.

Drives heavy ejector pins in plastic injection molding machines, utilizing the 2513.3 N push force to reliably strip large molded parts from deep cavities.
Acts as a robust knock-out or positioning cylinder in automated metal stamping presses, where the 100 mm stroke clears bulky formed blanks.
Applies downward clamping pressure in CNC woodworking routers, holding dense timber panels steady during aggressive routing operations.
When sizing this unit, consider stepping down to the SDA63, which yields 1558.6 N of push at 0.5 MPa, or moving up to the SDA100, which provides 3927 N at the same pressure. To finalize your order, confirm the 80 mm bore, 100 mm stroke, PT3/8 port, female rod-end thread (M14x1.5), and the absence of a magnet. If your application requires position holding upon air loss, note that this cylinder will drift; an external rod lock or pilot-operated check valve is required to secure the load.
Quick checklist
The SDA80X100 generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
This specific SKU lacks the -S piston magnet, so it cannot host reed or electronic switches. Additionally, end-of-stroke deceleration relies solely on a fixed NBR bumper, not a field-adjustable air cushion; for high-energy cycles, you should add an external shock absorber or slow the approach speed.
