About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X650TC
The AirTAC SC125X650TC is a double-acting pneumatic cylinder with a 125 mm bore and 650 mm stroke, supplied with a centre trunnion (TC) mount for pivoting applications. It delivers a substantial push force of 6136 N at 0.5 MPa and up to 11045 N at 0.9 MPa, making it suitable for heavy-duty linear actuation. The 32 mm diameter piston rod and 28 mm adjustable air cushion provide robust guidance and reliable end-of-stroke deceleration.
This model is part of the SC tie-rod series, which is an ISO 6430 class cylinder for this bore size, featuring a compact body length of 203 mm. The TC mount, which includes the TCM1 trunnion bracket (F-SC125TC), allows the cylinder to pivot freely, absorbing misalignment in swinging or articulating mechanisms. Standard PT ports and TPU seals are fitted, offering reliable operation in normal industrial environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X650TC Is Used
Heavy-Duty Clamping
Generates up to 11045 N of force for secure workpiece clamping in large CNC machining centres and welding fixtures.
Material Handling Gates
Actuates heavy diverter gates or chutes on aggregate and bulk material conveyors, with the trunnion mount allowing for a smooth, arcing motion.
Agricultural Equipment Actuation
Provides the high force and robust design needed for controlling heavy linkages, hoppers, or flow gates on farming and forestry machinery.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X650TC the Right Cylinder?
Select the SC125 bore when your application requires a force between 6136 N and 11045 N. If the load is lighter, consider stepping down to the SC100 bore, which provides 3927 N at 0.5 MPa. For heavier loads, the SC160 bore offers 10053 N at the same pressure. This 650 mm stroke is within the standard range for the 125 mm bore, but always check for potential rod buckling under high compressive loads. For a direct replacement, match the 125 mm bore, 650 mm stroke, PT port thread, centre trunnion (TC) mounting, and the absence of a magnet sensor option.
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 SC125X650TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No, this specific SC125X650TC model is fitted with standard TPU seals, which have an operating temperature range of -20 to +70 °C. For applications up to +150 °C, you would need to order the Viton seal option, designated by the suffix 'H' in the model code (e.g., SC125X650TCH).
