About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X280S
The SC160X280S is a double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. Its 40 mm diameter piston rod and 29 mm adjustable air cushion are engineered for heavy-duty linear applications requiring controlled end-of-stroke deceleration.
This model features a built-in magnet, enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for reliable position feedback. With a 280 mm stroke and a compact body length A of 239 mm, it fits machinery where a shorter overall footprint than an ISO 15552 cylinder is needed.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X280S Is Used
Heavy Press & Clamping
The 18095 N thrust at 0.9 MPa makes this cylinder ideal for hydraulic-press alternatives, die-casting clamping, and heavy assembly fixtures where consistent force and magnetic piston sensing are required.
Material Handling & Lifting
Provides the muscle for lifting and transferring heavy pallets or steel sheets in automated warehouses. The built-in magnet allows for mid-stroke position verification to coordinate with conveyors.
Sawmill & Wood Processing
Suited for log positioning and heavy-duty cutting gates. The adjustable cushion absorbs the high kinetic energy of large moving masses, while the magnetic sensors confirm gate open/close status in dusty environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X280S the Right Cylinder?
For applications needing more force, the SC200 bore provides 15708 N at 0.5 MPa. If a smaller footprint is required, the SC125 bore delivers 6136 N at the same pressure. This 280 mm stroke is within the standard range, but always verify that side loads are managed—an unsupported 40 mm rod extending 280 mm can experience bending under high radial forces. Use an external guide or rod support for off-axis loads.
When replacing an existing cylinder, match five critical points: 160 mm bore, 280 mm stroke, PT3/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. The SC series 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 AIRTAC SC125-160 Standard Cylinder SC160X280S 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 SC160X280S is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke end; it does not lock or hold the load. For load holding, you must add a pilot-operated check valve or an external mechanical brake.
