About the Airtac SC80 Standard Cylinder SC80X900TC
The AirTAC SC80X900TC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). With an 80 mm bore and a 900 mm stroke, it features a 25 mm diameter piston rod and an adjustable air cushion length of 28 mm to decelerate end-of-stroke impact. The total extended body length is approximately 1082 mm (body length A of 182 mm plus the 900 mm stroke).
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (order code F-SC80TC). The trunnion allows the cylinder to pivot, making it ideal for swinging or articulating loads. It uses the standard PT (Rc) port thread of 3/8 inch and operates on filtered air from 0.15 to 1.0 MPa within a temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X900TC Is Used
Material Handling Diverters
The 900 mm stroke and pivoting trunnion mount allow this cylinder to actuate long-throw diverter gates on conveyor systems, sorting packages or materials with a controlled swinging motion.
Welding Fixture Clamping
Delivers 4523 N of clamping force at 0.9 MPa for heavy steel fabrication jigs. The centre trunnion lets the cylinder swing into position, clearing the workpiece during loading and unloading.
Hopper Door Actuation
Controls the opening and closing of large hopper discharge doors on agricultural silos or bulk material bins, using the long 900 mm stroke for full gate travel and the trunnion to accommodate the door's arc path.
Is the Airtac SC80 Standard Cylinder SC80X900TC the Right Cylinder?
For applications requiring less force, consider stepping down to the 63 mm bore (1559 N at 0.5 MPa). If more force is needed, the 100 mm bore provides 3927 N at the same pressure. At a 900 mm stroke, the 25 mm rod is susceptible to bending under side loads; an external guide rail or a guided cylinder is strongly recommended to prevent rod bearing damage. For a direct replacement, match the 80 mm bore, 900 mm stroke, PT port thread, centre trunnion (TC) mounting, and ensure the replacement cylinder has the same tie-rod body design.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SC80X900TC FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It must replace another AirTAC SC tie-rod cylinder with an 80 mm bore and matching TC centre trunnion mount.
