About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250CB
The SC160X250CB is a heavy-duty double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). With a 250 mm stroke and a 40 mm diameter piston rod, it is built for industrial applications that demand high force and a pivoting mount.
This model features a CB rear double clevis mounting (fork/lug style, accessory F-SC160CB) that allows the cylinder body to pivot during operation, accommodating angular movement. The adjustable air cushion at each end (29 mm cushion length) decelerates the 160 mm bore piston smoothly, reducing end-of-stroke impact. Standard PT ports (PT3/4) and TPU seals for a -20 to +70 °C operating range complete the configuration.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250CB Is Used
Heavy Machinery Tilt Control
Controls the tilt angle of large agricultural or construction implements, using the rear clevis mount to pivot with the linkage while providing up to 18095 N of force.
Baler & Compactor Actuation
Drives the compression ram in recycling balers, where the 10053 N force at standard line pressure compacts cardboard, plastics, or textiles into dense bales.
Die Cushion & Clamping
Provides powerful, controlled clamping force for large forming dies or injection molds, with the adjustable cushion ensuring smooth, vibration-free operation at end-of-stroke.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250CB the Right Cylinder?
Select the SC160 when your application requires a force class around 10053 N at 0.5 MPa. If your load demands are lower, stepping down to the SC125 bore provides 6136 N push at the same pressure, potentially reducing air consumption and physical footprint. For higher forces, the SC200 bore offers 15708 N at 0.5 MPa.
This 250 mm stroke operates well within the 1500 mm maximum standard stroke for the 160 bore, so side-loading on the 40 mm rod is manageable for purely axial loads. For any stroke over 300 mm or when even minor side forces are present, always use an external guide or linear rail to protect the rod bearing from bending moments. To replace an existing cylinder, match five points: 160 mm bore, 250 mm stroke, PT3/4 port thread, CB rear double clevis mount, and the absence of a magnet.
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 SC160X250CB 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 force at 1.0 MPa is 2050 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder of the same bore and stroke (body length A is 239 mm). It is not dimensionally interchangeable with ISO 15552 cylinders. It is a direct replacement only for another AirTAC SC160 tie-rod cylinder with matching bore, stroke, PT ports, and CB rear double clevis mount.
