The AirTAC AirTAC SDA80X35B Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 35mm 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 SDA80X35B is a double-acting, single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted unibody design merges the barrel and covers into a highly shortened axial package, conserving valuable machine footprint where a conventional round-body unit would be too deep. The hard-anodized bore minimizes friction to support the standard 30-500 mm/s speed range.
This specific configuration includes the -B option, providing a male M22x1.5 threaded piston rod end for secure mechanical coupling to your load. End-of-stroke deceleration relies on fixed NBR bumpers rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. Because this SKU lacks the -S magnet, it cannot host position sensing switches.

Drives heavy plastic parts out of molding tools where the 2513.3 N extend force breaks the vacuum seal, utilizing the short body to fit within tight press platens.
Acts as a secondary resistance cylinder in light stamping presses, using its 35mm stroke and NBR bumpers to absorb the shock of metal forming operations.
Lifts heavy product layers onto shipping pallets, where the male M22x1.5 rod end securely bolts to the lifting fork without shearing under dynamic loads.
When sizing this unit, verify if the 2513.3 N output at 0.5 MPa fits your requirement. Stepping down to the SDA63 yields 1558.6 N, while moving up to the SDA100 provides 3927 N. Based on the 0.5 MPa figure, a safe working load is approximately 1508 N (60% capacity), translating to a vertical lift capability of about 128.1 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the piston. To hold a suspended load securely, integrate an external rod lock or pilot-operated check valve. Confirm your ordering essentials: 80mm bore, 35mm stroke, PT3/8 port, male M22x1.5 rod thread, and no sensor magnet.
Quick checklist
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2267.8 N. At 0.7 MPa, the push force is 3518.6 N. The theoretical maximum push force is 513 kgf at the 1.0 MPa pressure limit.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the -S variant for position sensing, and detection relies entirely on adding that magnet option.
