About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500
The SC160X500 is a heavy-duty double-acting tie-rod cylinder generating 10053 N of push force at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). Its 40 mm diameter piston rod and 500 mm stroke suit demanding linear actuation where substantial force and moderate travel are required.
This 160 mm bore cylinder uses PT3/4 ports and an M36x2 rod thread. The body length A is 239 mm, giving a total extended length of approximately 739 mm. An adjustable pneumatic cushion (29 mm length) decelerates the piston near stroke end to reduce impact, but it does not hold the load if air pressure is lost.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500 Is Used
Sawmill Log Handling
Positions and clamps large-diameter logs on carriages and infeeds, using the 10053 N push force at 0.5 MPa to hold timber firmly during cutting operations.
Heavy Press Feeding
Shuttles steel plate or heavy tooling into hydraulic forming presses. The adjustable cushion absorbs the kinetic energy of the moving platen for smoother cycle rates.
Dock Leveler Actuation
Raises and lowers heavy-duty loading dock levelers and yard ramps. The tie-rod construction handles the continuous shock and vibration of forklift traffic.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500 the Right Cylinder?
Select the SC160 bore when your application needs between roughly 9425 N and 18095 N of force. If your load is lighter, stepping down to the SC125 bore (6136 N push at 0.5 MPa) can reduce air consumption and physical size. For heavier loads, the SC200 bore provides 15708 N at 0.5 MPa.
At a 500 mm stroke, ensure side loads are minimal or use an external guide. The 40 mm rod is robust, but long unsupported strokes under lateral force can cause rod bearing wear and bending. To replace an existing cylinder, match five points exactly: 160 mm bore, 500 mm stroke, PT3/4 port thread, basic mounting (no bracket), and confirm whether a magnet (-S) is needed for sensors.
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 SC160X500 FAQ
At the standard 0.5 MPa operating pressure, push force is 10053 N and pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. The SC160X500 is a double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of stroke. For position holding without live pressure, add a pilot-operated check valve or an external rod brake.
