About the Airtac SC80 Standard Cylinder SC80X650TC
The SC80X650TC is an 80 mm bore, 650 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod family. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod with an M20x1.5 rod thread.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket, allowing the cylinder to pivot during actuation. The body length A is 182 mm, giving a total extended length of approximately 832 mm. It uses PT1/4 ports and features an adjustable air cushion (28 mm length) to decelerate the piston smoothly at stroke ends.

Where the Airtac SC80 Standard Cylinder SC80X650TC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it ideal for actuating diverter gates on conveyor lines where the cylinder must swing through an arc.
Clamping Fixtures
Delivers up to 4523 N of clamping force at 0.9 MPa for holding workpieces during machining or welding, with the TC mount simplifying integration into pivoting clamp arms.
Agricultural Equipment Actuation
Commonly used to control chutes, hopper doors, or sorting mechanisms on farming machinery, where the trunnion mount absorbs misalignment and the TPU seals handle dusty environments.
Is the Airtac SC80 Standard Cylinder SC80X650TC the Right Cylinder?
Select the SC80 when your application requires between 2513 N and 4523 N of force. If your load is lighter, stepping down to a 63 mm bore reduces the push force to 1559 N at 0.5 MPa; for heavier demands, the 100 mm bore provides 3927 N at the same pressure. Always match the replacement cylinder across five points: bore, stroke, port thread (PT), mounting accessory (TC centre trunnion with TCM1 bracket, part F-SC80TC), and magnet option (none on this model).
At a 650 mm stroke, the 25 mm rod is extended significantly. Avoid unguided side loads that can bend the rod or damage the bearing. For applications with offset loads, use an external guide rail or switch to a guided cylinder to protect the rod and ensure reliable cycling.
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 SC80X650TC FAQ
At 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.
Yes, provided the original cylinder matches all five key specifications: 80 mm bore, 650 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and no built-in magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
