About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100TC
The AirTAC SC125X100TC is a double-acting pneumatic cylinder with a 125 mm bore and 100 mm stroke, supplied with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it generates 6136 N pushing and 5734 N pulling, rising to a robust 11045 N at the maximum operating pressure of 0.9 MPa.
This model features a 32 mm piston rod with an M27x2 knuckle thread and PT1/2 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke. The TC mount includes the TCM1 bracket (part code F-SC125TC), allowing the cylinder to pivot as the load moves through an arc.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100TC Is Used
Conveyor Diverter Gates
The 6136 N push force at 0.5 MPa easily actuates heavy diverter gates on wide conveyor lines, with the trunnion mount absorbing the pivoting motion.
Welding Fixture Clamping
Delivers 11045 N of clamping force at 0.9 MPa to secure large weldments. The centre trunnion allows the cylinder body to swing clear for part loading.
Agricultural Equipment Actuation
Ideal for raising and lowering heavy implements on harvesters or tillers. The robust 32 mm rod and trunnion pivot handle dirty, high-vibration environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100TC the Right Cylinder?
Choose the SC125 bore when your application needs between 6136 N and 11045 N of push force. For a lighter load, stepping down to the SC100 bore reduces push force to 3927 N at 0.5 MPa. This 100 mm stroke is well within the 1500 mm maximum standard stroke for the 125 bore.
To ensure a direct replacement, match five points: 125 mm bore, 100 mm stroke, PT port thread, centre trunnion (TC) mounting, and the absence of a magnet. The SC series is a tie-rod cylinder, shorter than ISO 15552 profiles, so interchangeability is limited to other AirTAC SC tie-rod cylinders with the same specifications.
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 AIRTAC SC125-160 Standard Cylinder SC125X100TC FAQ
At 0.7 MPa, the theoretical push force is 8590 N. The maximum operating force at 0.9 MPa is 11045 N. For precise dynamic sizing, factor in your application's friction and load angle.
No, the SC is a tie-rod cylinder and is physically shorter than a standard ISO 15552 profile cylinder. It will not be a drop-in dimensional replacement. It directly replaces another AirTAC SC125 cylinder with matching stroke, PT ports, and TC mount.
