About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450S
The SC160X450S is a double-acting tie-rod cylinder delivering substantial force for heavy-duty linear applications. At 0.5 MPa air pressure it generates 10053 N pushing and 9425 N pulling, rising to 18095 N push at the maximum operating pressure of 0.9 MPa, driven through a rigid 40 mm diameter piston rod.
This model includes a factory-installed magnet (suffix -S) along the piston, enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for contactless position feedback. With a 450 mm stroke and a body length A of 239 mm, the total extended length reaches 689 mm, and the 29 mm adjustable air cushion at each end decelerates high-inertia loads smoothly.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450S Is Used
Palletizer & Heavy Lift
The 18095 N max push force at 0.9 MPa drives lift carriages and pallet elevators, handling multi-ton loads with controlled cushioning.
Press & Clamping Fixture
Delivers over 10 kN of steady clamping force for hydraulic-press alternatives in assembly, bonding, or forming operations.
Logistics Divert & Transfer
Moves heavy totes or pallets across roller conveyors; the built-in magnet provides end-of-stroke confirmation via barrel-mounted sensors.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450S the Right Cylinder?
Select the SC160 bore when your application requires a push force above 10000 N at standard shop air; if the load is lighter, stepping down to an SC125 (6136 N at 0.5 MPa) can reduce air consumption and footprint. For strokes of 450 mm, ensure the load is guided and free of side forces—an unsupported 40 mm rod at this extension is vulnerable to bending under off-axis loads; use an external guide or linear bearing.
To replace an existing cylinder, match five points exactly: 160 mm bore, 450 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting configuration. The SC series is a tie-rod design 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 SC160X450S FAQ
At 0.5 MPa the cylinder pushes with 10053 N and pulls with 9425 N. At the maximum operating pressure of 0.9 MPa the push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG, DMSG, or EMSG sensors clamp directly onto the tie-rod barrel without any additional brackets or bands.
