About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350SCB
The AirTAC SC160X350SCB is a double-acting single-rod pneumatic cylinder delivering a substantial 10053 N push force at 0.5 MPa (18095 N at 0.9 MPa). With a 160 mm bore, 350 mm stroke, and a 40 mm diameter piston rod, this tie-rod cylinder provides the muscle needed for heavy pressing, clamping, and lifting operations.
The -S suffix equips this model with a built-in magnet, allowing direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel for precise position feedback. The -CB suffix specifies a rear double clevis (fork) mount (accessory F-SC160CB), ideal for pivoting applications where the cylinder body must articulate. TPU seals and PT ports complete the standard configuration, operating reliably from -20 to +70 C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350SCB Is Used
Heavy Press & Forming
The 18095 N max thrust at 0.9 MPa makes this cylinder suitable for hydraulic-press alternatives in light forming, riveting, and die-cushion applications where controlled pneumatic force is preferred.
Pallet Lifting & Tipping
With a 350 mm stroke and rear clevis pivot, the SC160X350SCB excels in lifting and tipping heavy pallets or bins on production lines, providing smooth, controlled motion under substantial loads.
Large Valve Actuation
The high force output and magnetic piston sensing make it ideal for automating large industrial gate or butterfly valves, confirming open/closed status via barrel-mounted sensors in water treatment or processing plants.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350SCB the Right Cylinder?
Select the SC160 when your application demands forces in the 10 kN class at standard plant pressure. For a step down in force, the SC125 bore offers 6136 N push at 0.5 MPa; for even higher capacity, the SC200 bore provides 15708 N at the same pressure. At a 350 mm stroke, ensure side loads are minimal or use an external guide system—the 40 mm rod can experience bending stress if unguided off-axis forces are present.
For replacement, match five key points: 160 mm bore, 350 mm stroke, PT port thread, the CB rear double clevis mounting, and the -S magnet for sensor compatibility. This is a genuine AirTAC tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to 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 SC160X350SCB 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, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. The SC160 is a standard double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add a pilot-operated check valve, external rod lock, or mechanical brake.
