About the Airtac SC80 Standard Cylinder SC80X65STC
The AirTAC SC80X65STC is a robust double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a powerful mid-bore actuator for industrial automation. This model features a 25 mm diameter piston rod, PT3/8 port connections, and a 28 mm adjustable air cushion for smooth end-of-stroke deceleration.
Configured with a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC suffix, supplied with TCM1 bracket), this cylinder is ready for pivoting applications. The 65 mm stroke is well within the standard range, and the TPU seals provide reliable operation from -20 to +70 °C. Sourced as a genuine AirTAC component, it offers dependable performance for demanding tasks.

Where the Airtac SC80 Standard Cylinder SC80X65STC Is Used
Clamping & Fixturing
Provides 2513 N of clamping force at standard line pressure, ideal for holding workpieces securely in CNC machining centres and welding fixtures.
Part Diverter Gates
The centre trunnion mount allows the cylinder to pivot, making it perfect for actuating diverter gates on conveyor systems to sort or merge product lines.
Agricultural Implement Control
Controls chute doors or flow gates on harvesting and processing equipment, with the magnet enabling position feedback to a central controller.
Is the Airtac SC80 Standard Cylinder SC80X65STC the Right Cylinder?
For applications requiring this force class, the SC80 bore provides a significant step up from the SC63, which offers 1559 N at 0.5 MPa. If your load demands more, consider the SC100 bore delivering 3927 N. The centre trunnion mount allows the cylinder body to pivot, ideal for loads that move through an arc. To ensure a correct replacement, match five key points: 80 mm bore, 65 mm stroke, PT3/8 port thread, TC centre trunnion mount, and the built-in magnet for sensor compatibility.
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 SC80X65STC FAQ
At 0.5 MPa (standard shop air), 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.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace with another AirTAC SC series cylinder matching the 80 mm bore, 65 mm stroke, PT ports, TC mount, and magnet option.
