About the Airtac SC80 Standard Cylinder SC80X170STC
The SC80X170STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and 170 mm stroke, this model features a 25 mm diameter piston rod and a 28 mm adjustable air cushion at each end, providing reliable deceleration for mid-range automation tasks.
This configuration includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for contactless position sensing. The TC centre trunnion mount is supplied with the TCM1 bracket, enabling the cylinder to pivot and handle swinging loads effectively. It is a genuine AirTAC SC series tie-rod cylinder, factory-equipped with PT ports and standard TPU seals.

Where the Airtac SC80 Standard Cylinder SC80X170STC Is Used
Conveyor Diverters
The 2513 N push force at 0.5 MPa easily actuates heavy-duty diverter gates on packaging lines, while the centre trunnion mount allows the cylinder body to pivot as the gate swings through its arc.
Clamping & Welding Fixtures
Ideal for robust pneumatic clamping in jigs. The built-in magnet provides end-of-stroke confirmation via solid-state sensors, ensuring the part is securely clamped before a welding or machining cycle begins.
Agricultural Implement Control
Provides reliable actuation for chute deflectors or tensioners on farm machinery. The TPU seals and tie-rod construction handle dusty conditions, and the trunnion mount absorbs misalignment in the linkage.
Is the Airtac SC80 Standard Cylinder SC80X170STC the Right Cylinder?
Select the SC80 bore when your application requires a push force between the 628 N of a 40 mm bore and the 1559 N of a 63 mm bore at 0.5 MPa. The 170 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a standard, readily available configuration. For a direct replacement, match the 80 mm bore, 170 mm stroke, PT port thread, centre trunnion (TC) mount, and the integrated magnet (-S) sensor capability.
At this stroke length, the 25 mm rod is robust, but if the load applies a significant side force, consider an external guide rail or a guided cylinder to prevent rod bearing wear and ensure smooth operation.
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 SC80X170STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
No. The SC80 is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston rod can drift. To hold a load safely without live pressure, you must add an external rod lock or a pilot-operated check valve.
