About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160S
The AirTAC SC125X160S is a double-acting single-rod pneumatic cylinder delivering 6136 N push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 32 mm rod diameter and a 160 mm stroke, it is built for heavy linear actuation tasks where sensor feedback is required.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position sensing. The adjustable air cushion (28 mm length) decelerates the piston smoothly, and the PT1/2 port supplies ample flow for the 125 mm bore.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160S Is Used
Heavy Part Sorting Gates
The 6136 N push force at 0.5 MPa easily diverts large packages or heavy components on high-speed conveyor lines. The built-in magnet enables sensor-confirmed gate position for reliable sortation logic.
Press-Fit Assembly Stations
Delivers up to 11045 N at 0.9 MPa for pressing bearings, bushings, or pins into place. Integrated magnetic sensors verify full extension and retraction to prevent incomplete assembly cycles.
Pallet Lifting & Indexing
With a robust 32 mm rod and 160 mm stroke, this cylinder indexes heavy pallets in automated storage systems. The adjustable cushion protects the structure from impact damage during rapid cycling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160S the Right Cylinder?
Select the SC125 when your application needs a force step up from the SC100 (3927 N at 0.5 MPa). For higher thrust still, the SC160 offers 10053 N at the same pressure. The 160 mm stroke is well within the 1500 mm maximum standard stroke for this bore, keeping lead times short.
To ensure a drop-in replacement, match five points: 125 mm bore, 160 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration. This is an ISO 6430 class big-bore cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC tie-rod cylinders of the same specification.
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 SC125X160S FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes. The -S suffix indicates a built-in magnet within the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors onto the cylinder's tie-rod barrel to detect piston position without additional brackets.
