About the Airtac SC80 Standard Cylinder SC80X620TC
The AirTAC SC80X620TC is a double-acting pneumatic cylinder with an 80 mm bore and a 620 mm stroke, supplied with a centre trunnion (TC) mounting for pivoting applications. At 0.5 MPa it produces 2513 N of push force and 2268 N of pull force, while at the maximum operating pressure of 0.9 MPa the push force reaches 4523 N, driven by a 25 mm diameter piston rod.
This model includes a PT3/8 port and an M20x1.5 rod thread. The 28 mm adjustable air cushion at each end smoothly decelerates the piston, and the tie-rod construction keeps the overall body length compact at 182 mm plus the 620 mm stroke. The TC mount ships complete with the TCM1 trunnion bracket (part code F-SC80TC), allowing the cylinder to swing as the load moves through an arc.

Where the Airtac SC80 Standard Cylinder SC80X620TC Is Used
Conveyor Diverter Gates
The 620 mm stroke and centre trunnion mount let this cylinder pivot to swing diverter arms on packaging lines, handling 2513 N of push force at standard line pressure.
Material Lift & Tilt Tables
With 4523 N of force at 0.9 MPa, the SC80X620TC powers scissor-lift or tilt mechanisms, where the trunnion mount accommodates the changing angle during elevation.
Clamp & Fixture Actuation
Delivers 2268 N of pull force for heavy-duty clamping in welding or assembly fixtures, with the adjustable cushion protecting the tooling from impact at end of stroke.
Is the Airtac SC80 Standard Cylinder SC80X620TC the Right Cylinder?
For a lower force requirement, stepping down to a 63 mm bore reduces the push force to 1559 N at 0.5 MPa, while a 100 mm bore steps it up to 3927 N. When replacing an existing cylinder, match five key points: 80 mm bore, 620 mm stroke, PT3/8 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the absence of a built-in magnet.
With a 620 mm stroke, the extended rod has significant unsupported length. Any side load can bend the 25 mm rod or damage the bearing, so use an external linear guide or ensure the load is constrained to move purely axially. For applications with inherent side forces, consider a guided cylinder instead.
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 SC80X620TC FAQ
At 0.7 MPa (7 bar) the push force is 3518 N. The maximum push force at the 0.9 MPa operating limit is 4523 N, and the theoretical force at 1.0 MPa is 513 kgf.
This model has PT3/8 tapered pipe threads. If your existing fittings are G3/8 (BSP parallel), you would need to order the G-thread variant or use appropriate adapters. Always confirm the port thread type, mounting style, and stroke length match before ordering.
