About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X850TC
The AirTAC SC160X850TC is a double-acting tie-rod cylinder delivering substantial force for heavy-duty linear applications. With a 160 mm bore operating at 0.5 MPa, it generates 10053 N of push force and 9425 N of pull force, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa. The 40 mm diameter piston rod and 29 mm adjustable air cushion are engineered to manage high inertial loads smoothly.
This model features an 850 mm stroke with a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC160TC), allowing the cylinder to pivot during operation. The total extended body length is approximately 1089 mm. Standard PT ports (PT3/4) and TPU seals with a -20 to +70 °C temperature range make it a robust choice for demanding factory automation tasks.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X850TC Is Used
Heavy Machinery Tilt Control
The centre trunnion mount and 18095 N max force at 0.9 MPa make this cylinder perfect for controlling the tilt angle of large hoppers, chutes, or grader blades in agricultural and construction machinery.
Palletiser Pusher
Delivers the high force needed to push heavy pallets or bulk loads onto conveyor systems. The adjustable cushion decelerates the 40 mm rod smoothly at the end of the 850 mm stroke, protecting the load and machine structure.
Heavy-Duty Clamping Fixture
Provides a powerful 10053 N clamping force at standard shop air pressure for securing large weldments or castings. The pivoting TC mount allows the cylinder to self-align as the clamp engages.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X850TC the Right Cylinder?
Select the SC160 when your application requires a push force between roughly 6.1 kN (the SC125 at 0.5 MPa) and 15.7 kN (the SC200 at 0.5 MPa). The 40 mm rod is robust, but at an 850 mm stroke, significant side loads can cause rod deflection and premature bearing wear; always use an external guide rail or rod alignment coupler to absorb transverse forces. The TC centre trunnion mount is ideal for applications where the cylinder body must swing through an arc.
For a direct replacement, match these five specifications exactly: 160 mm bore, 850 mm stroke, PT3/4 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and no magnet. This SC model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.

- ✓ 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 SC160X850TC FAQ
At 0.7 MPa operating pressure, the theoretical push force is 14074 N and the pull force on the retract stroke is 9425 N (the pull force value is for 0.5 MPa; confirm the 0.7 MPa pull force from the full datasheet). The maximum force at 0.9 MPa is 18095 N.
No. The SC160X850TC is a standard double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. To hold a load safely, you must add a pilot-operated check valve or an external mechanical rod lock.
