About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X135S
The AirTAC SC125X135S is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 32 mm piston rod and an M27x2 rod thread, this 125 mm bore model is built for demanding linear tasks. The 135 mm stroke falls well within the standard offering for this bore size.
This model includes the -S suffix, indicating a built-in magnet embedded in the piston. This allows for direct, non-contact position sensing using AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors, which simply clamp onto the cylinder's tie-rod barrel. The standard TPU seals provide a reliable operating temperature range of -20 to +70 °C, and the body length A is 203 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X135S Is Used
Heavy Part Transfer
The 6136 N push force at 0.5 MPa easily shifts large castings or fabrications on conveyor lines, with the 135 mm stroke providing a decisive push-off distance.
Industrial Compaction
Ideal for waste or recycling compactors, the SC125X135S applies up to 11045 N of force at 0.9 MPa to compress materials into dense, manageable forms.
Clamping & Fixturing
Delivers consistent, high-force clamping for large weldments or machining fixtures. The built-in magnet enables sensor confirmation of clamp engagement before a cycle starts.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X135S the Right Cylinder?
Select the SC125 when your application requires a force class between the SC100 (3927 N push at 0.5 MPa) and the larger SC160 (10053 N push at 0.5 MPa). For strokes of 300 mm or more, evaluate side-load conditions on the 32 mm rod; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
When replacing an existing unit, ensure a 5-point match: 125 mm bore, 135 mm stroke, PT port thread, the basic mounting configuration, and the presence of a magnet for sensors (-S suffix). This SC series is a tie-rod cylinder 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 SC125X135S FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 6136 N of push force and 5734 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N.
The -S suffix in SC125X135S means it has a built-in magnetic piston. You can mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel slots without any additional brackets, enabling simple and reliable end-of-stroke or mid-stroke position detection.
