The AirTAC AirTAC SDA80X55B Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 55mm 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 SDA80X55B is a double-acting single-rod compact cylinder engineered for substantial actuation tasks, delivering 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly abbreviated package, drastically reducing axial mounting depth where a conventional round-body unit would protrude too far into the machinery. The 80 mm bore features a hard-anodized inner wall and a PT3/8 port, while the -B option specifies a male M22x1.5 piston rod end for robust mechanical coupling to your load.
Deceleration at stroke limits relies on a fixed NBR bumper at each end rather than a field-tunable air cushion. This design choice means that for high-energy cycles approaching the 30-500 mm/s speed range, you should either slow the approach or install an external shock absorber to prevent impact damage. Furthermore, this specific SKU lacks a piston magnet, so it cannot directly host AirTAC reed or electronic switches without changing to an -S variant.

Drives the ejection plate inside a plastic injection molding machine, utilizing the 2513.3 N push force to reliably strip finished parts from the die cavity within a confined press footprint.
Positions heavy steel blanks at the entry of a mechanical stamping press, where the 25 mm male-thread rod securely attaches to the staging fixture and the compact body minimizes frame interference.
Actuates diverter gates on high-throughput pallet conveyors, providing the necessary 128.1 kg vertical lift margin to redirect heavy loads without extending deep into the conveyor structure.
Selecting this 80 mm bore model provides a theoretical maximum push of 513 kgf at 1.0 MPa, with a computed safe working load around 1508 N (approximately 60% of the 0.5 MPa rating) and a vertical lift capacity near 128.1 kg using a 2:1 safety margin. If your application requires less force, the SDA63 offers 1558.6 N of push at 0.5 MPa; conversely, if you need substantially more power, the SDA100 steps up to 3927 N at the same pressure. When ordering, confirm the 80 mm bore, 55 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the absence of a magnet.
Because this is a standard double-acting cylinder, it will not hold a load in place if air pressure drops or the directional valve is centered. The piston will drift, and the fixed bumper only decelerates the stroke near the end caps without acting as a mechanical lock. If your machinery demands fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push and 3175 N pull at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, has a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C at speeds of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Additionally, this specific SKU lacks the -S option, meaning it has no piston magnet and cannot support reed or electronic switches. The -B designation indicates it has a male M22x1.5 rod end instead of the standard female thread.
