About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X170S
The AirTAC SC160X170S is a double-acting tie-rod cylinder delivering 10053 N push force at 0.5 MPa (18095 N at 0.9 MPa). Its 170 mm stroke suits medium-travel clamping and pressing tasks where sensor feedback is required. The built-in magnet allows CMSG/DMSG/EMSG reed or solid-state sensors to mount directly on the barrel for rod-position detection.
This model uses a 40 mm diameter piston rod with M36×2 male threads and PT3/4 ports. The adjustable air cushion (29 mm length) decelerates the piston near stroke end, reducing impact. Operating pressure spans 0.15–1.0 MPa with TPU seals rated for -20 to +70 °C. The body length A is 239 mm, giving an extended length of approximately 409 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X170S Is Used
Heavy Part Clamping
The 10053 N force at 0.5 MPa securely clamps large weldments or castings in machining fixtures, with the magnet confirming jaw position.
Pallet Stop & Lift
Stops and lifts heavy pallets on conveyor lines. The -S magnet provides end-of-stroke signals to the PLC for sequencing.
Press & Forming Assist
Delivers 18095 N at 0.9 MPa for pressing bushings or forming sheet metal, with adjustable cushion to manage high-speed cycling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X170S the Right Cylinder?
Select the SC160X170S when you need the 10053 N push force of a 160 mm bore and sensor feedback. For lighter loads, the SC125 bore offers 6136 N at 0.5 MPa; for heavier, the SC200 bore provides 15708 N. At 170 mm stroke, rod bending is not a primary concern, but always avoid direct side loads on the rod.
For replacement, match five points: bore (160 mm), stroke (170 mm), port thread (PT), the built-in magnet (-S suffix), and the basic mounting style. This is a 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 SC160X170S FAQ
At 0.5 MPa the push force is 10053 N; at 0.7 MPa it is 14074 N; and at the maximum operating pressure of 0.9 MPa it 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 (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel tie-rods to detect piston position.
