About the Airtac SC80 Standard Cylinder SC80X290STC
The SC80X290STC is an 80 mm bore double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa (up to 4523 N at 0.9 MPa). Its 290 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a ready-to-ship standard configuration. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for piston position feedback.
This model features a centre trunnion mount (TC) with the TCM1 bracket, allowing the cylinder to pivot during operation—ideal for swinging or articulating loads. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration. Ports are PT3/8, and the body length A is 182 mm, giving an extended length of approximately 472 mm.

Where the Airtac SC80 Standard Cylinder SC80X290STC Is Used
Part Diverter Gates
The centre trunnion mount and 290 mm stroke allow this cylinder to pivot a diverter gate on a conveyor line, reliably sorting packages with 2513 N of push force.
Welding Fixture Clamps
With a built-in magnet for sensor confirmation, this cylinder pivots a clamping arm into place on a welding fixture, ensuring the part is secured before the cycle starts.
Grain Chute Positioning
The trunnion-mounted SC80X290STC articulates a discharge chute on a grain handling system, using its 4523 N maximum force to shift the chute under heavy material flow.
Is the Airtac SC80 Standard Cylinder SC80X290STC the Right Cylinder?
Choose the SC80 when your application needs between 2513 N and 4523 N of pneumatic force. If you need less force, step down to the SC63 bore which provides 1559 N at 0.5 MPa. For higher force requirements, the SC100 bore offers 3927 N at the same pressure. Always match the bore, 290 mm stroke, PT3/8 port thread, TC centre trunnion mount, and the -S magnet option when replacing an existing unit.
For this 290 mm stroke, ensure the load is guided and side forces are minimized. Long unsupported strokes on a single rod can create a bending moment at the rod bearing; use an external guide rail or a guided cylinder if significant side loads are present.
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 SC80X290STC FAQ
At the standard 0.5 MPa operating pressure, 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.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel to detect piston position without any additional brackets.
