About the Airtac SC125-160 Standard Cylinder SC160X850
The AirTAC SC160X850 is a double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa, scaling up to a substantial 18095 N at the maximum operating pressure of 0.9 MPa. With an 850 mm stroke and a 40 mm diameter piston rod, this model is built for heavy industrial linear tasks requiring significant force over a long travel distance.
This cylinder features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, protecting the end caps from impact. The body length A is 239 mm, making the total extended length approximately 1089 mm. It uses a PT3/4 port and an M36x2 rod thread, and operates reliably within a -20 to +70 °C range with its standard TPU seals.

Where the Airtac SC125-160 Standard Cylinder SC160X850 Is Used
Sawmill Log Handling
Provides the high force and long stroke needed to clamp, index, or kick large logs and cants in a sawmill carriage, operating reliably in dusty conditions.
Heavy Agricultural Machinery
Actuates large chute deflectors, hopper doors, or folding implements on harvesters and spreaders, where a robust 10053 N push force at 0.5 MPa is required.
Scrap Metal Baler Ram
Drives the compression ram in a medium-sized scrap baler, using its 18095 N maximum force to compact metal turnings or cans into dense bales for recycling.
Is the Airtac SC125-160 Standard Cylinder SC160X850 the Right Cylinder?
Select the SC160X850 when your application demands a push force in the 10000 N class at standard plant pressure. If your force requirement is lower, stepping down to an SC125 bore reduces the push force to 6136 N at 0.5 MPa, potentially saving space and air consumption. For strokes of this length, ensure the load is guided and perfectly axial; a 40 mm rod extending 850 mm is vulnerable to bending under side loads, so an external guide rail or rod-alignment coupler is essential.
For a direct replacement, match five key specifications: the 160 mm bore, 850 mm stroke, PT3/4 port thread, the specific mounting accessory (if any), and the magnet option. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC160X850 FAQ
At 0.7 MPa operating pressure, the SC160X850 generates a theoretical push force of 14074 N and a pull force of 9425 N. The maximum force at 0.9 MPa is 18095 N push.
No. The SC160X850 is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift. To hold a load safely, you must add an external pilot-operated check valve or a mechanical rod lock.
