About the Airtac SC80 Standard Cylinder SC80X85TC
The AirTAC SC80X85TC is an 80 mm bore double-acting pneumatic cylinder with an 85 mm stroke, supplied with a centre trunnion (TC) mount and TCM1 bracket for pivoting applications. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide reliable deceleration, while the tie-rod construction keeps the overall body length compact at just 182 mm (A dimension).
At 0.5 MPa this cylinder generates 2513 N of push force and 2268 N of pull force, rising to 4523 N push at the maximum operating pressure of 0.9 MPa. The PT1/8 port thread and M20x1.5 rod thread are standard for this bore, and the TPU seals suit ambient temperatures from -20 to +70 °C. This genuine AirTAC SC unit is built for consistent cycling in industrial automation.

Where the Airtac SC80 Standard Cylinder SC80X85TC Is Used
Conveyor Diverter Gate
The SC80X85TC pivots on its centre trunnion to actuate a diverter arm, sorting packages by weight or barcode. The 2513 N push force at 0.5 MPa easily shifts medium cartons on a powered roller line.
Clamp & Weld Fixture
In a robotic welding cell, this cylinder swings a clamping arm into place. The 28 mm air cushion absorbs impact at the end of the 85 mm stroke, protecting the fixture from vibration and extending tooling life.
Grain Chute Positioning
Mounted on a centre trunnion, the cylinder tilts a grain chute between two silo inlets. The 25 mm rod and tie-rod body handle dusty conditions, and the 4523 N max force moves even when chute is partially loaded.
Is the Airtac SC80 Standard Cylinder SC80X85TC the Right Cylinder?
Choose the SC80 bore when your application needs between roughly 2500 N and 4500 N of pneumatic force. If your load is lighter, stepping down to the SC63 bore saves air and space (1559 N push at 0.5 MPa); for heavier demands the SC100 bore delivers 3927 N at the same pressure. The 85 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
For replacement, match five points: 80 mm bore, 85 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC80TC/TCM1 bracket set, and no magnet. The TC mount lets the cylinder pivot during operation—ensure the trunnion pins are aligned and the load is guided to prevent side forces from reaching the rod bearings.
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 SC80X85TC FAQ
At 0.7 MPa operating pressure the SC80 bore produces 3518 N of push force (extending) and 3171 N of pull force (retracting). The pull force is lower because air pressure acts on the piston area minus the 25 mm rod cross-section.
Yes, provided the original is also an 80 mm bore, 85 mm stroke, PT-ported tie-rod cylinder with a centre trunnion mount. The SC80X85TC includes the TCM1 trunnion bracket (part of the F-SC80TC set). Verify that the trunnion pin centre distance and the M20x1.5 rod thread match your existing linkage.
