About the Airtac SC80 Standard Cylinder SC80X135STC
The AirTAC SC80X135STC is an 80 mm bore, 135 mm stroke double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide robust, smooth deceleration for medium-to-heavy linear motion tasks.
This specific model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion (TC) mount with the TCM1 bracket (F-SC80TC) for pivoting applications. The standard PT ports and TPU seals suit filtered-air systems operating from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X135STC Is Used
Conveyor Diverter Gates
The 2513 N push force and centre trunnion mount allow the cylinder to pivot smoothly, directing packages or materials onto different conveyor lanes with reliable, cushioned end-of-stroke action.
Welding Fixture Clamping
Provides strong, consistent clamping force for metal fabrication jigs. The built-in magnet enables sensor feedback to confirm clamp position before the welding cycle begins.
Grain Chute Positioning
Controls the angle of discharge chutes in agricultural handling equipment. The trunnion mount handles the pivoting motion, while the TPU seals and air cushion withstand dusty, repetitive cycling.
Is the Airtac SC80 Standard Cylinder SC80X135STC the Right Cylinder?
Choose the SC80 when your application needs roughly 2500 N of force; the smaller SC63 bore offers 1559 N at 0.5 MPa if space is tighter, while the SC100 steps up to 3927 N for heavier loads. For this 135 mm stroke, side-load bending is not a primary concern, but always align the load axially with the rod to maximise seal and bearing life.
To replace an existing cylinder, match five points: 80 mm bore, 135 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This ensures a direct dimensional and functional swap with another AirTAC SC series unit.
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 SC80X135STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 2513 N extending (push) and 2268 N retracting (pull). 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. The '-S' in the model code indicates a built-in magnet on the piston. This allows you to directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel to detect piston position without any additional brackets.
