About the Airtac SC80 Standard Cylinder SC80X850H
The SC80X850H is an 80 mm bore double-acting pneumatic cylinder with an extended 850 mm stroke, built on the rugged AirTAC SC tie-rod platform. Its 25 mm diameter piston rod and 28 mm adjustable air cushion at each end manage deceleration smoothly, while the body length A of 182 mm keeps the base envelope compact. With Viton (FKM) seals, this model is rated for continuous operation from 0 to +150 °C, making it suitable for hot environments where standard TPU seals would degrade.
At the standard0.5 MPa supply, the cylinder pushes with2513 N and pulls with2268 N; raising pressure to0.9 MPa boosts the extending thrust to4523 N. The850 mm stroke is well within the1500 mm maximum standard stroke for bore80, so this is a standard-catalogue configuration. Ports are PT3/8, and the rod thread is M20x1.5. This genuine AirTAC unit is filtered-air ready and proof-tested to1.5 MPa.

Where the Airtac SC80 Standard Cylinder SC80X850H Is Used
Hot-Press Actuation
Viton seals allow the SC80X850H to operate reliably inside heated platen presses, thermoforming stations, or autoclave loading systems where ambient temperatures reach 150 °C, providing consistent 2.5 kN+ force for clamping and ejection.
Long-Reach Material Handling
The850 mm stroke is ideal for pushers, lift-assist arms, or long-travel diverters on packaging and logistics lines, moving totes or cartons across wide conveyor gaps with controlled cushion deceleration.
Foundry & Kiln Gate Drives
With high-temperature FKM seals and a robust tie-rod construction, this cylinder suits damper and gate controls on kilns, ovens, and foundry equipment, resisting heat soak while delivering up to4523 N of breakout force at0.9 MPa.
Is the Airtac SC80 Standard Cylinder SC80X850H the Right Cylinder?
Choose the SC80 bore when your application needs between roughly2500 N and4500 N of push force on normal shop air. If your load is lighter and you can accept a smaller envelope, stepping down to the63 mm bore (1559 N at0.5 MPa) saves space and air consumption; for heavier loads, the100 mm bore delivers3927 N at the same pressure. Because the stroke is850 mm, confirm that side loads are minimal or use an external guide rail—an unsupported25 mm rod at this extension can bend under off-centre forces, leading to premature bearing and seal wear.
For a drop-in replacement, match five points exactly:80 mm bore,850 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and no built-in magnet. The SC is a tie-rod cylinder and is shorter than an ISO15552 profile, so it will not interchange with ISO15552-dimensioned actuators. Only another AirTAC SC80 (or an identically specified tie-rod cylinder) will fit the same mounting footprint and port locations.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC80 Standard Cylinder SC80X850H FAQ
At0.5 MPa (≈73 psi) the extending force is2513 N. At0.7 MPa it rises to3518 N, and at the maximum operating pressure of0.9 MPa the cylinder delivers4523 N. The theoretical force at1.0 MPa is513 kgf, but AirTAC rates the working range only up to1.0 MPa. For pulling (retracting) force, subtract the rod area: pull force at0.5 MPa is2268 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO15552 profile cylinder of the same bore and stroke, so the mounting dimensions and port positions are different. To replace this model, match the80 mm bore,850 mm stroke, PT3/8 ports, basic mounting, and Viton seal suffix exactly with another AirTAC SC80X850H or an identically specified tie-rod cylinder.
