The AirTAC AirTAC SDA80X55 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 SDA80X55 is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened axial footprint, conserving valuable machine mounting depth where conventional round bodies cannot fit. The hard-anodized bore ensures durability, while the PT3/8 air port feeds the chamber efficiently.
This 80 mm bore unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not a field-adjustable air cushion. Because this SKU lacks the -S piston magnet, it cannot host magnetic switches. The 25 mm rod utilizes a female M14x1.5 thread for load coupling, and buyers should note the piston drifts if air pressure is lost, as the bumper acts only as an end stop rather than a locking brake.

Provides robust 2513.3 N push force to eject dense plastic components from injection molding machinery within tight axial frame constraints.
Indexes heavy metal forming tools on press brakes, utilizing the 25 mm rod and female M14x1.5 thread for rigid, high-load mechanical coupling.
Drives vertical lifting arms in automated palletizing cells, where the short riveted body minimizes vertical space requirements and structural interference.
When sizing this model, stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to the SDA100 provides 3927 N. This SDA80X55 strikes a balance, offering a safe working load of roughly 1508 N (about 60 percent of its 0.5 MPa capacity) and a vertical lift capacity near 128.1 kg with a 2:1 safety margin. To hold a suspended load without live pressure, you must integrate an external rod lock or a pilot-operated check valve, as the fixed bumper will not prevent drifting. Confirm your ordering essentials: 80 mm bore, 55 mm stroke, PT3/8 port, female rod thread, and no sensor magnet.
Quick checklist
The SDA80X55 generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates at 30-500 mm/s with a maximum standard stroke of 130 mm.
No, this model uses a fixed NBR bumper to decelerate at stroke end, which is not an adjustable air cushion. Additionally, this specific SKU lacks the -S piston magnet, so it cannot support reed or electronic switches; you would need the -S variant for position sensing.
