About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500CA
The AirTAC SC125X500CA is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa. With a 500 mm stroke and a 32 mm diameter piston rod, this model is built for heavy linear actuation tasks in industrial automation.
This configuration includes a rear single clevis mount (CA) for pivoting applications, allowing the cylinder to swing as it strokes. The body length A is 203 mm, and the adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke. Ports are PT1/2 with an M27x2 rod thread.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500CA Is Used
Heavy-Duty Clamping
The 11045 N force at 0.9 MPa makes this cylinder ideal for powerful workpiece clamping in CNC machining centres and welding fixtures.
Agricultural Implement Actuation
With a pivoting rear clevis and high force output, it reliably operates heavy levers and linkages on tillage or harvesting equipment.
Pallet Lift and Transfer
The 500 mm stroke combined with 6136 N at 0.5 MPa efficiently lifts and transfers heavy pallets in material handling systems.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500CA the Right Cylinder?
Choose the SC125 bore when your application needs between 6136 N and 11045 N of force. For a lighter load, stepping down to the SC100 bore provides 3927 N at 0.5 MPa. For a heavier push, the SC160 offers 10053 N at the same pressure. The 500 mm stroke is within the standard range for this bore (max 1500 mm).
For a stroke of this length, ensure the load is guided and side forces are minimal. The 32 mm rod can bend under significant side load; use an external guide rail or a guided cylinder if off-axis forces are present. When replacing, match bore (125), stroke (500), port thread (PT), mounting (rear clevis CA), and magnet option (none).
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 SC125X500CA 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 'CA' suffix designates a rear single clevis mount (part code F-SC125CA). This allows the cylinder body to pivot on a single lug at the rear cap, accommodating angular movement during the stroke.
