The AirTAC AirTAC SDA80X85 Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 85mm 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 SDA80X85 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 securely joins the barrel, rear cover, piston, and rod, yielding an exceptionally short axial footprint that slides into tight machine cavities where conventional round bodies fail. The 80 mm bore features a hard-anodized inner wall and a two-way piston seal for prolonged service life.
This 85 mm stroke unit relies on a fixed NBR bumper at each end to decelerate the end stop rather than an adjustable air cushion. Operating at speeds between 30-500 mm/s, it uses a PT3/8 port and a 25 mm piston rod. This specific SKU lacks the internal magnet, meaning it cannot host AirTAC reed or electronic switches for position sensing.

Ejecting heavy formed sheet metal from stamping presses using the 2513.3 N extend force, capitalizing on the short body to fit within tight press tooling envelopes.
Driving the separation of thick injection mold halves where 128.1 kg of vertical lift is required, utilizing the 85 mm stroke to clear the part safely.
Raising loaded machining pallets within an automated cell, where the fixed NBR bumper absorbs the end-stop energy of the 25 mm rod under high dynamic loads.
When sizing this actuator, evaluate your neighbours: stepping down to the SDA63 yields 1558.6 N push at 0.5 MPa, while the larger SDA100 provides 3927 N at the same pressure. For the SDA80X85, the safe working load is approximately 1508 N (60% of the 0.5 MPa figure), translating to a vertical lift capacity of about 128.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 80 mm bore, 85 mm stroke, PT3/8 port, female M14x1.5 rod thread, and no sensor magnet.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered. The piston will drift, and the fixed rubber bumper only slows travel near the stroke limits without acting as a mechanical brake. If your application demands strict position holding, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
The SDA80X85 generates 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 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 a piston magnet. To use AirTAC reed or electronic switches, you must select the SDA80X85S variant which has the built-in magnet riding in the body grooves.
