The AirTAC AirTAC SDA80X50B Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 50mm 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 SDA80X50B 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 to minimize axial mounting depth, offering a highly space-efficient footprint compared to traditional round-body units in heavy-duty machinery.
This specific SKU features a male M22x1.5 threaded piston rod end for robust mechanical coupling to your load. The bore is hard-anodized for longevity, and the system operates at 30-500 mm/s. It relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Note that this configuration omits the piston magnet, so it cannot host magnetic switches.

Provides the 2513.3 N push force required to knock finished plastic parts out of heavy injection moulding tools, utilizing the male M22x1.5 rod for secure ejector plate coupling.
Handles robust workpiece positioning and clamping at coil feeding stations, where the short riveted body saves valuable axial space in tight press enclosures.
Drives vertical elevation mechanisms in automated palletizers, safely lifting loads around 128.1 kg with a 2:1 safety margin when operated at 0.5 MPa.
When sizing this actuator, evaluate your neighbours: stepping down to the SDA63 yields 1558.6 N push at 0.5 MPa, while stepping up to the SDA100 provides 3927 N at the same pressure. Based on the 2513.3 N output, the safe working load is approximately 1508 N (about 60% capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred; the fixed bumper only decelerates near the stroke end and does not function as a lock or brake. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 80 mm bore, 50 mm stroke, PT3/8 port, male M22x1.5 rod thread, and no magnet.
Quick checklist
This 80 mm bore 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 force is 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles temperatures from -20 to +70 C, and runs at speeds of 30-500 mm/s.
This specific SKU lacks the internal piston magnet, so it cannot accept reed or electronic switches; you would need the -S variant for sensing. Additionally, end-of-stroke deceleration is handled by a fixed NBR bumper, not an adjustable air cushion. For high-energy cycles, slow the approach or add an external shock absorber.
