About the Airtac SC80 Standard Cylinder SC80X63TC
The SC80X63TC is an 80 mm bore, 63 mm stroke double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm air cushion provide smooth deceleration for short-stroke positioning tasks.
This model is factory-configured with a TC centre trunnion mount, supplied together with the TCM1 bracket (part code F-SC80TC), allowing the cylinder to pivot during operation. The compact tie-rod body measures 182 mm in length A, giving a total extended length of approximately 245 mm.

Where the Airtac SC80 Standard Cylinder SC80X63TC Is Used
Part Diverter Gates
Short 63 mm stroke with centre trunnion pivoting actuates diverter flaps on packaging conveyors, directing cartons between lanes at moderate speed.
Clamp & Fixture Actuation
2513 N at 0.5 MPa provides ample clamping force for CNC fixture swing clamps. The trunnion mount allows the cylinder to self-align as the clamp arm rotates.
Valve Positioning
Operates quarter-turn ball or butterfly valves where the 63 mm stroke matches the actuator linkage throw. Centre trunnion absorbs the arc motion without side-loading the rod.
Is the Airtac SC80 Standard Cylinder SC80X63TC the Right Cylinder?
Choose the SC80 bore when 63 mm cylinders (1559 N at 0.5 MPa) are undersized; step up to SC100 (3927 N at 0.5 MPa) if higher force is needed. For replacement, match bore, 63 mm stroke, PT1/8 port thread, TC centre trunnion mounting, and confirm magnet requirement—this model has no built-in magnet.
At 63 mm stroke, rod bending is minimal, but any side load should still be managed with an external guide. The TC trunnion mount suits pivoting applications where the cylinder body must swing through an arc.
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 SC80X63TC FAQ
At 0.5 MPa supply pressure, the 80 mm bore generates 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes, provided the original is an AirTAC SC80 tie-rod cylinder with 63 mm stroke, PT3/8 ports, and centre trunnion mounting. The TC mount code includes the TCM1 bracket (F-SC80TC). Confirm port thread type (PT vs G) and magnet sensor requirement before ordering.
