About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X530S
The SC125X530S is a double-acting single-rod pneumatic cylinder from the AirTAC SC tie-rod series, combining a 125 mm bore with a 530 mm stroke. It produces a push force of 6136 N at 0.5 MPa and reaches 11045 N at the maximum operating pressure of 0.9 MPa, driven by a 32 mm diameter piston rod with M27x2 male threads.
This model includes the -S suffix, indicating a built-in magnet embedded in the piston. This allows easy, non-invasive mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for precise end-of-stroke or mid-stroke position feedback. The adjustable air cushion at each end decelerates the piston over 28 mm to reduce impact noise.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X530S Is Used
Heavy-Duty Clamping
Delivers up to 11045 N of force at 0.9 MPa for securely holding large workpieces during machining or welding operations, with sensor confirmation of the clamped position.
Pallet Lift & Transfer
The 530 mm stroke and 6136 N push force at standard pressure are ideal for lifting and transferring heavy pallets or totes between conveyor levels in logistics hubs.
Material Forming Press
Provides the high, consistent force needed for pressing, bending, or forming sheet metal and composites, with magnetic sensors ensuring full stroke completion on every cycle.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X530S the Right Cylinder?
For applications needing slightly less force in the same form factor, the SC100 bore generates 3927 N push at 0.5 MPa. If a higher force is required, stepping up to the SC160 bore provides 10053 N at the same pressure. Always match replacement cylinders on five key points: bore (125 mm), stroke (530 mm), PT port thread, the built-in magnet (-S), and the basic mounting style.
With a 530 mm stroke, the extended rod length increases the risk of bending under side loads. For this stroke class, consider an external linear guide or a guided cylinder if the load is not perfectly axial, to protect the rod bearing and piston seals from premature wear.
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 SC125X530S 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 increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes, the -S suffix designates a built-in magnet. You can directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel's tie-rod slots to detect piston position without any additional brackets.
