About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X65S
The AirTAC SC160X65S is a double-acting tie-rod cylinder delivering 10053 N push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 65 mm stroke, this model is built for heavy linear actuation tasks where a compact retracted length is needed.
This variant includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for precise, non-contact end-of-stroke or mid-stroke position feedback. The adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly, reducing impact noise and wear in high-cycle applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X65S Is Used
Heavy Press & Clamp Fixtures
Generates over 10 kN of push force at standard shop air, ideal for pneumatic toggle clamps, assembly presses, and holding fixtures that require high clamping pressure on large workpieces.
Material Handling & Stops
The 65 mm stroke with magnetic piston sensing provides reliable part stops, diverter gates, and pallet lifts on conveyor lines, with sensor confirmation of the retracted or extended position.
Industrial Automation Machinery
Suited for actuating heavy doors, chutes, and hopper gates in harsh industrial environments, where the adjustable cushion protects the end caps from high inertial loads.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X65S the Right Cylinder?
Choose the SC160 bore when your application requires a push force between roughly 628 N (SC40) and 18095 N (SC160 at 0.9 MPa). If 10053 N at 0.5 MPa exceeds your need, stepping down to an SC125 (6136 N at 0.5 MPa) can reduce air consumption and footprint. For strokes over 300 mm, evaluate side-load conditions carefully; a 40 mm rod is robust, but sustained lateral forces still demand an external guide or a guided cylinder to protect the rod bearing and seals.
To ensure a correct replacement, match five points: 160 mm bore, 65 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This SC cylinder 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 SC160X65S 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.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's tie-rod slots for position sensing without additional brackets.
