About the Airtac SC125-160 Standard Cylinder SC160X125CB
The SC160X125CB is a double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 125 mm stroke and a 40 mm piston rod, this model is built for heavy linear actuation tasks where a pivoting rear mount is required.
This configuration includes a CB rear double clevis mounting, allowing the cylinder body to pivot during operation. The tie-rod construction houses adjustable air cushioning with a 29 mm cushion length to decelerate the 160 mm bore piston smoothly, reducing end-of-stroke impact.

Where the Airtac SC125-160 Standard Cylinder SC160X125CB Is Used
Heavy Machinery Linkages
The rear double clevis mount lets the cylinder pivot, perfect for actuating heavy-duty lever arms and mechanical linkages in industrial machinery.
Agricultural Equipment
With 10053 N of force at standard pressure, this cylinder powers dump mechanisms and positioners on harvesters, spreaders, and tillage tools.
Press and Clamping Systems
Delivers up to 18095 N of clamping force at 0.9 MPa for heavy part holding in welding fixtures and assembly presses.
Is the Airtac SC125-160 Standard Cylinder SC160X125CB the Right Cylinder?
For applications needing more force, the SC200 bore offers 15708 N at 0.5 MPa. If a 125 mm bore with 6136 N is sufficient, stepping down can reduce air consumption. The CB rear double clevis (F-SC160CB) allows the cylinder to swing in an arc, making it ideal for linkages and dump mechanisms.
When replacing this cylinder, match five points: 160 mm bore, 125 mm stroke, PT3/4 port thread, the CB rear double clevis mount, and the non-magnetic piston (no -S suffix). This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC160 tie-rod units.
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 SC125-160 Standard Cylinder SC160X125CB FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 standards. It directly replaces another AirTAC SC160 tie-rod cylinder with matching stroke, port, and CB mount.
