The AirTAC AirTAC SDA80X45H Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 45mm 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 SDA80X45H is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatic actuation within a minimal axial footprint. Utilizing a short riveted body design, it significantly reduces mounting depth compared to conventional round-body units, making it ideal for tight machinery layouts. This specific SKU features an 80 mm bore, generating 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, and includes a fluororubber (FKM) seal for enhanced thermal and oil resistance.
The unit incorporates a hard-anodized bore and a fixed NBR bumper at each end to decelerate the stroke, though it is not an adjustable air cushion or a locking brake. It operates at speeds between 30-500 mm/s and utilizes a PT3/8 port alongside a 25 mm piston rod. Note that this configuration lacks a piston magnet, so it cannot support magnetic sensing without selecting the -S variant.

Provides robust 2513.3 N push force to eject dense plastic parts from injection molding tools, where the FKM seals withstand high ambient machine heat.
Actuates heavy material guides in a sheet metal stamping line, utilizing the 45 mm stroke to position steel blanks accurately before the press cycles.
Drives vertical lift gates on automated palletizing stations, handling loads up to 128.1 kg safely while fitting into the compact machinery envelope.
When sizing this model, consider stepping down to the SDA63, which yields 1558.6 N of push at 0.5 MPa, or stepping up to the SDA100 for 3927 N at 0.5 MPa. The 80 mm bore offers a safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Ensure your ordering essentials match the requirements: 80 mm bore, 45 mm stroke, PT3/8 port, female rod-end thread (M14x1.5), and FKM seals.
Because this is a double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. The fixed bumpers only decelerate the rod near the stroke endpoints and do not function as a lock. For suspended or vertical loads that require position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 80 mm bore cylinder provides 2513.3 N of push force and 2267.8 N of pull force. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and operational speeds of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, meaning it cannot support AirTAC reed or electronic switches. You would need to select the -S option code variant to enable magnetic sensing. Additionally, this model uses fixed NBR bumpers to decelerate the stroke end rather than an adjustable air cushion, so external shock absorbers may be needed for high-energy loads.
