About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X520CB
The SC160X520CB is a double-acting tie-rod cylinder delivering a substantial 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 40 mm diameter piston rod and a 520 mm stroke, this model is built for heavy linear actuation tasks where a pivoting rear mount is essential.
This specific configuration includes a CB rear double clevis mount (fork/lug style, accessory F-SC160CB), allowing the cylinder body to pivot during operation. The 29 mm adjustable air cushion at each end decelerates the 40 mm rod and load smoothly, reducing end-of-stroke impact. Ports are PT3/4 with an M36x2 rod thread, and the total extended body length is approximately 759 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X520CB Is Used
Heavy Equipment Articulation
The rear double clevis mount allows this cylinder to pivot, making it ideal for controlling the articulation of booms, buckets, or plows on agricultural and construction machinery.
Large-Scale Material Handling
With over 10,000 N of force at standard shop air, this cylinder powers large bin gates, heavy-part pushers, and transfer stations in mining, recycling, and foundry conveyor systems.
Industrial Press & Clamp Actuation
The high force output at 0.9 MPa (18095 N) suits heavy-duty clamping and pressing fixtures in metal fabrication, where the pivoting clevis mount accommodates the mechanism's arc of motion.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X520CB the Right Cylinder?
Select the SC160 when your application requires push forces in the 10053 N (at 0.5 MPa) to 18095 N (at 0.9 MPa) range. If your force requirement is lower, stepping down to an SC125 bore provides 6136 N of push at 0.5 MPa in a lighter package. For even higher forces, the SC200 bore offers 15708 N at the same pressure. For this 520 mm stroke, ensure the rod is not subjected to significant side loading; if lateral forces are present, use an external guide system or a guided cylinder to prevent rod bending and premature bearing wear.
To guarantee a drop-in replacement, match five key points: 160 mm bore, 520 mm stroke, PT3/4 port thread, the CB rear double clevis mounting accessory, and the absence of a magnet on this non-S model. This cylinder is a direct replacement for another AirTAC SC160 of identical configuration.
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 SC160X520CB 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 AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 standards. For a direct replacement, you must match an existing AirTAC SC160 with the same bore, stroke, PT3/4 ports, and CB rear double clevis mount.
